Question 1Verbal logic and argument evaluation

An analyst at the Presidential Security Service reviews four statements regarding perimeter surveillance sensor deployment: 1. If perimeter thermal cameras are activated, micro-radar detection is deployed. 2. Micro-radar detection is deployed only if acoustic gunshot sensors are calibrated. 3. Acoustic gunshot sensors are calibrated. 4. Perimeter thermal cameras are activated. Which of the following must be true?

  1. Perimeter thermal cameras are activated, but micro-radar detection is not deployed.
  2. Both micro-radar detection is deployed and acoustic gunshot sensors are calibrated. Correct answer.
  3. If acoustic gunshot sensors are calibrated, perimeter thermal cameras must be deactivated.
  4. Acoustic gunshot sensors are calibrated, but micro-radar detection is definitely absent.

Explanation

From statement (4), thermal cameras are activated. By modus ponens on statement (1), micro-radar detection is deployed. Statement (2) states that micro-radar detection requires acoustic gunshot calibration (Radar -> Acoustic), which is consistent with statement (3) affirming calibration. Therefore, micro-radar detection is deployed and acoustic sensors are calibrated.

Question 2Verbal logic and argument evaluation

Consider the following security assessment: 'All close protection agents who undergo advanced evasive driving training are qualified for motorcade lead escort duty. No agent qualified for motorcade lead escort duty is permitted to carry uninspected secondary sidearms.' Which conclusion necessarily follows?

  1. All agents permitted to carry uninspected secondary sidearms have undergone evasive driving training.
  2. No agent who undergoes advanced evasive driving training is permitted to carry uninspected secondary sidearms. Correct answer.
  3. Every agent qualified for motorcade lead escort duty has undergone advanced evasive driving training.
  4. Some agents who carry uninspected secondary sidearms are qualified for motorcade lead escort duty.

Explanation

This follows the classic universal syllogism (Barbara/Celarent variant): All A are B, and No B are C. Therefore, No A are C. Since all advanced driving agents (A) are qualified for motorcade lead escort (B), and no agent qualified for motorcade lead escort (B) is permitted to carry uninspected secondary sidearms (C), no agent who undergoes advanced evasive driving training is permitted to carry uninspected sidearms.

Question 3Verbal logic and argument evaluation

A protocol officer makes the following statement regarding a diplomatic summit security detail: 'Either the inner security perimeter is manned by Presidential Security Service agents or the venue entrance is monitored by metropolitan tactical police officers, but not both.' If it is proven that the venue entrance is monitored by metropolitan tactical police officers, which statement must be true?

  1. Both units are deployed simultaneously to the inner security perimeter.
  2. The inner security perimeter is not manned by Presidential Security Service agents. Correct answer.
  3. Neither unit is deployed to the diplomatic summit.
  4. The inner security perimeter is manned by Presidential Security Service agents.

Explanation

The premise is an exclusive disjunction (XOR): P XOR Q. Under exclusive disjunction, exactly one of the two disjuncts is true. If Q (venue entrance monitored by metropolitan tactical police) is true, then P (inner security perimeter manned by PSS agents) must be false.

Question 4Verbal logic and argument evaluation

Read the following policy statement on emergency communications: 'Whenever the Presidential command vehicle switches to satellite fallback frequencies, all tactical escort units must immediately acknowledge receipt over encrypted VHF. If any tactical escort unit fails to acknowledge receipt, the route coordinator must issue a stop-movement directive.' Suppose the route coordinator did NOT issue a stop-movement directive. What can be deduced with certainty?

  1. Every tactical escort unit acknowledged receipt over encrypted VHF. Correct answer.
  2. The route coordinator was disconnected from the VHF tactical net.
  3. The Presidential command vehicle switched to satellite fallback frequencies.
  4. The Presidential command vehicle did not switch to satellite fallback frequencies.

Explanation

The second rule is conditional: 'If any unit fails to acknowledge (~All_Ack), then coordinator issues stop-movement (Stop)'. Applying modus tollens: We are given ~Stop (coordinator did not issue a stop-movement directive). Therefore, ~(~All_Ack), which means all tactical escort units acknowledged receipt over encrypted VHF.

Question 5Verbal logic and argument evaluation

A situational report states: 'If the security advance team (선발경호팀) identifies line-of-sight vulnerabilities on high-rise structures surrounding the motorcade route, counter-sniper observer teams are posted on opposite rooftops. Counter-sniper observer teams were not posted on opposite rooftops.' Which conclusion is validly drawn?

  1. Line-of-sight vulnerabilities were identified, but counter-sniper observer teams were unavailable.
  2. The motorcade route was rerouted through underground tunnels.
  3. The security advance team did not identify line-of-sight vulnerabilities on high-rise structures. Correct answer.
  4. Counter-sniper observer teams were deployed at ground level instead.

Explanation

Let V be 'advance team identifies line-of-sight vulnerabilities' and C be 'counter-sniper observer teams are posted on opposite rooftops'. The premise is V -> C. We are given ~C (counter-sniper observer teams were not posted). By modus tollens (~C -> ~V), we validly conclude ~V (the security advance team did not identify line-of-sight vulnerabilities on high-rise structures).

Question 6Verbal logic and argument evaluation

Which of the following propositions expresses the logical contrapositive of the rule: 'If an unauthorized aerial vehicle enters the designated presidential security airspace (경호공역), the electronic countermeasure (ECM) jammer is activated'?

  1. If an unauthorized aerial vehicle does not enter the designated presidential security airspace, the electronic countermeasure jammer is not activated.
  2. An unauthorized aerial vehicle enters the airspace only if the electronic countermeasure jammer is not activated.
  3. If the electronic countermeasure jammer is not activated, an unauthorized aerial vehicle has not entered the designated presidential security airspace. Correct answer.
  4. If the electronic countermeasure jammer is activated, an unauthorized aerial vehicle has entered the designated presidential security airspace.

Explanation

The contrapositive of a conditional proposition 'If P, then Q' (P -> Q) is logically equivalent to 'If not Q, then not P' (~Q -> ~P). Here, P is 'unauthorized drone enters security airspace' and Q is 'ECM jammer is activated'. Thus, the contrapositive is: 'If the ECM jammer is not activated, an unauthorized aerial vehicle has not entered the airspace'.

Question 7Verbal logic and argument evaluation

Examine the following statements regarding the qualification of security detail drivers: 1. If an agent does not hold a Class 1 Large Vehicle license, they cannot operate the primary armored limousine. 2. An agent who has not logged at least 200 hours of skid-pad evasive maneuvers is not permitted to operate in the inner motorcade ring. 3. Agent Park operates the primary armored limousine in the inner motorcade ring. Which conclusion must be true regarding Agent Park?

  1. Agent Park is qualified to pilot helicopter VIP transports.
  2. Agent Park holds a Class 1 Large Vehicle license, but has not logged 200 hours of skid-pad maneuvers.
  3. Agent Park was granted a special exemption from vehicle licensing requirements.
  4. Agent Park holds a Class 1 Large Vehicle license and has logged at least 200 hours of skid-pad evasive maneuvers. Correct answer.

Explanation

Statement (1) states: ~Class1 -> ~Operate_Limo. Contrapositive: Operate_Limo -> Class1. Since Agent Park operates the primary limousine, Park must hold a Class 1 Large Vehicle license. Statement (2) states: ~200Hours -> ~Inner_Ring. Contrapositive: Inner_Ring -> 200Hours. Since Park operates in the inner ring, Park must have logged at least 200 hours. Combining these yields that Park satisfies both requirements.

Question 8Verbal logic and argument evaluation

Consider the following argument regarding electronic surveillance around the presidential residence: 'Some advanced wireless interception antennas deployed around the perimeter are passive scanners. All passive scanners generate zero electromagnetic emission signatures. Therefore, some systems that generate zero electromagnetic emission signatures are capable of intercepting foreign diplomatic communications.' Which of the following premises, if added, makes the argument logically valid?

  1. Only active radars are capable of intercepting foreign diplomatic communications.
  2. Some passive scanners are incapable of intercepting commercial communications.
  3. All advanced wireless interception antennas deployed around the perimeter are capable of intercepting foreign diplomatic communications. Correct answer.
  4. No system generating zero electromagnetic emission signatures can detect encrypted microwave transmissions.

Explanation

Let A = advanced interception antennas, P = passive scanners, Z = zero emission systems, and D = capable of intercepting foreign diplomatic communications. Given premises: 1. Some A are P. 2. All P are Z. From (1) and (2), Some A are Z. To conclude 'Some Z are D', if we add 'All A are D' (All advanced antennas are capable of intercepting foreign diplomatic communications), then since Some A are Z, those members of A that are Z are also D. Thus, 'Some Z are D' is logically established.

Question 9Verbal logic and argument evaluation

Read the following summary regarding close protection equipment: 'All close protection ballistic vests deployed for presidential bodyguard duty meet Level III-A NIJ standards. Some vests meeting Level III-A NIJ standards incorporate flexible titanium trauma plates. No vest incorporating flexible titanium trauma plates exceeds 4.5 kilograms in total operational weight.' Based on these statements, which of the following statements must be true?

  1. All close protection ballistic vests incorporate flexible titanium trauma plates.
  2. No Level III-A ballistic vest incorporates titanium trauma plates.
  3. Every ballistic vest that does not exceed 4.5 kilograms is deployed for presidential bodyguard duty.
  4. Some Level III-A ballistic vests do not exceed 4.5 kilograms in total operational weight. Correct answer.

Explanation

Premises: 'Some Level III-A vests (L) have titanium plates (T)' (Some L are T), and 'No vest with titanium plates (T) exceeds 4.5 kg (W)' (No T are W). Since some L are T and all T are non-W, those vests in L that are in T are non-W. Therefore, 'Some Level III-A vests do not exceed 4.5 kg' is logically guaranteed.

Question 10Verbal logic and argument evaluation

A threat assessment report states: 'If foreign state intelligence agents are conducting surveillance in the capital, they either use diplomatic cover or establish front trading companies. If they establish front trading companies, their corporate accounts exhibit high-volume wire transfers from offshore tax havens. An audit of foreign corporate registries revealed no high-volume wire transfers from offshore tax havens among suspected entities.' Which conclusion is logically guaranteed?

  1. All foreign diplomats in the capital are active intelligence officers.
  2. Offshore tax havens have ceased cooperating with foreign intelligence services.
  3. Foreign state intelligence agents are not conducting surveillance in the capital.
  4. If foreign state intelligence agents are conducting surveillance in the capital, they use diplomatic cover. Correct answer.

Explanation

Let S = surveillance in capital, D = diplomatic cover, F = front trading companies, and W = wire transfers from tax havens. Premises: 1. S -> (D or F) 2. F -> W 3. ~W From (2) and (3), by modus tollens, we have ~F. Substitute ~F into (1): S -> (D or false), which simplifies to S -> D. In other words, if foreign agents are conducting surveillance, they must be using diplomatic cover.

Question 11Verbal logic and argument evaluation

An emergency response protocol at the Blue House (청와대/대통령실) states: 'Whenever an unauthorized drone breaches the inner security zone (1선 구역), both the RF jamming beam is directed and the physical capture net launcher is armed. If the physical capture net launcher is armed, the rooftop observation team must confirm a clear downrange trajectory.' During an incident, the rooftop observation team was unable to confirm a clear downrange trajectory. What can be concluded?

  1. An unauthorized drone did not breach the inner security zone. Correct answer.
  2. The inner security zone was evacuated immediately.
  3. The unauthorized drone was brought down by anti-aircraft artillery.
  4. The RF jamming beam was successfully directed at the drone.

Explanation

Chain of logic: Drone_Breach -> (RF_Jam AND Net_Armed). Also Net_Armed -> Clear_Trajectory. We are given ~Clear_Trajectory. By modus tollens, ~Net_Armed. Since Net_Armed is false, the conjunction (RF_Jam AND Net_Armed) is false. By modus tollens on the first conditional, ~(Drone_Breach) must be true: an unauthorized drone did not breach the inner security zone.

Question 12Verbal logic and argument evaluation

Read the following statements regarding VIP security advance planning: 1. If a motorcade route includes high-elevation overpasses, tactical counter-sniper teams are deployed or structural blast shields are inspected. 2. If structural blast shields are inspected, structural engineering officers are dispatched. 3. Tactical counter-sniper teams were not deployed. 4. Structural engineering officers were not dispatched. What must be true regarding the motorcade route?

  1. The motorcade route includes high-elevation overpasses.
  2. The motorcade route does not include high-elevation overpasses. Correct answer.
  3. Tactical counter-sniper teams were reassigned to airport arrival security.
  4. Structural blast shields were inspected without engineering officers.

Explanation

By statement (2), Blast_Shields -> Engineers_Dispatched. Statement (4) gives ~Engineers_Dispatched. By modus tollens, ~Blast_Shields. Statement (3) gives ~Sniper_Teams. Therefore, both disjuncts of (Sniper_Teams OR Blast_Shields) are false, making the disjunction false. Statement (1) says Overpasses -> (Sniper_Teams OR Blast_Shields). By modus tollens, ~Overpasses: the motorcade route does not include high-elevation overpasses.

Question 13Verbal logic and argument evaluation

A complex intelligence dossier presents five rules regarding five suspected threat actors (V, W, X, Y, Z): - If V is in the capital, W is also in the capital. - Exactly one of X and Y is in the capital. - If W is in the capital, then X is NOT in the capital. - If Z is in the capital, then both V and Y are in the capital. - Z is in the capital. Which of the following must be the complete and accurate list of all suspected threat actors who are in the capital?

  1. V, W, Y, and Z only Correct answer.
  2. V, W, X, and Z only
  3. Z and Y only
  4. V, W, and Z only

Explanation

Let us trace the deductive chain starting from the established fact: Z is in the capital. 1. Since Z is in the capital, Rule 4 requires both V and Y to be in the capital. (In capital: {Z, V, Y}) 2. Since V is in the capital, Rule 1 requires W to be in the capital. (In capital: {Z, V, Y, W}) 3. Since W is in the capital, Rule 3 requires X to NOT be in the capital. (X is absent) 4. Rule 2 requires exactly one of X and Y to be in the capital. Since Y is present and X is absent, this condition is satisfied. Therefore, the complete list of actors in the capital is V, W, Y, and Z.

Question 14Data interpretation and quantitative foundations

A security logistics unit reviews the fuel consumption and distance traveled by four escort motorcade divisions during an operational training exercise: | Division | Total Distance (km) | Total Fuel Consumed (L) | | :--- | :---: | :---: | | Division A | 600 | 120 | | Division B | 750 | 125 | | Division C | 800 | 160 | | Division D | 900 | 200 | Which division achieved the highest fuel efficiency (greatest kilometers per liter)?

  1. Division C
  2. Division B Correct answer.
  3. Division D
  4. Division A

Explanation

Calculate kilometers per liter (km / L) for each division: - Division A: 600 / 120 = 5.0 km/L - Division B: 750 / 125 = 6.0 km/L - Division C: 800 / 160 = 5.0 km/L - Division D: 900 / 200 = 4.5 km/L Division B achieved the highest fuel efficiency at 6.0 km/L.

Question 15Data interpretation and quantitative foundations

A metal detection walkthrough gate (문형 금속탐지기) logs passenger screening data at an airport VIP pavilion. Over a 3-hour period, the system processed the following numbers of individuals: - Hour 1: 240 individuals (with 12 secondary alarm inspections) - Hour 2: 300 individuals (with 18 secondary alarm inspections) - Hour 3: 260 individuals (with 10 secondary alarm inspections) What was the overall secondary alarm inspection rate across the entire 3-hour period?

  1. 5.8%
  2. 5.0% Correct answer.
  3. 6.0%
  4. 4.2%

Explanation

Calculate total individuals screened: Total individuals = 240 + 300 + 260 = 800 individuals. Calculate total secondary alarm inspections: Total alarms = 12 + 18 + 10 = 40 inspections. Overall secondary alarm inspection rate = (40 / 800) * 100 = (1 / 20) * 100 = 5.0%.

Question 16Data interpretation and quantitative foundations

A communication security team tests radio transmitter battery degradation across four cold-weather temperature conditions: | Temperature (°C) | Standard Battery Life (Hours) | Low-Power Battery Life (Hours) | | :--- | :---: | :---: | | 10°C | 12.0 | 18.0 | | 0°C | 10.0 | 15.0 | | -10°C | 7.5 | 12.0 | | -20°C | 6.0 | 9.0 | At what temperature is the ratio of Low-Power Battery Life to Standard Battery Life the greatest?

  1. 0°C
  2. 10°C
  3. -20°C
  4. -10°C Correct answer.

Explanation

Calculate the ratio (Low-Power Life / Standard Life) for each temperature: - At 10°C: 18.0 / 12.0 = 1.50 - At 0°C: 15.0 / 10.0 = 1.50 - At -10°C: 12.0 / 7.5 = 1.60 - At -20°C: 9.0 / 6.0 = 1.50 The ratio is greatest at -10°C (1.60).

Question 17Data interpretation and quantitative foundations

A tactical driving instructor tracks the braking distance (in meters) of an armored presidential limousine traveling at 80 km/h across four different road surface conditions: | Surface Condition | Dry Asphalt | Wet Asphalt | Packed Snow | Black Ice | | :--- | :---: | :---: | :---: | | Braking Distance (m) | 36.0 | 45.0 | 72.0 | 108.0 | By what factor does the braking distance increase on Black Ice compared to Dry Asphalt?

  1. 4.0 times
  2. 2.5 times
  3. 3.0 times Correct answer.
  4. 3.5 times

Explanation

Calculate the factor increase: Braking distance on Black Ice = 108.0 meters. Braking distance on Dry Asphalt = 36.0 meters. Factor = 108.0 / 36.0 = 3.0 times.

Question 18Data interpretation and quantitative foundations

A training division records the number of qualifying rounds fired by 200 bodyguard recruits. The passing requirement is achieving at least 85 points out of 100: | Score Range | Number of Recruits | | :--- | :---: | | 95–100 | 30 | | 90–94 | 50 | | 85–89 | 60 | | 80–84 | 35 | | 75–79 | 15 | | Below 75 | 10 | What percentage of the recruits successfully passed the marksmanship qualification?

  1. 70.0% Correct answer.
  2. 80.0%
  3. 75.0%
  4. 65.0%

Explanation

Passing requirement is 85 points or above. Sum recruits in score ranges >= 85: - 95–100: 30 recruits - 90–94: 50 recruits - 85–89: 60 recruits Total passing recruits = 30 + 50 + 60 = 140 recruits. Total recruits = 200. Passing percentage = (140 / 200) * 100 = 70.0%.

Question 19Verbal logic and argument evaluation

For this exercise, accept the following statements: 'All statutory boards must submit annual reports to their supervising ministries. The Land Transport Authority (LTA) is a statutory board.' Which option is a logical deduction from the statements?

  1. Only LTA has complied with the submission requirement this year.
  2. Ministries are required to publish these reports publicly within thirty days.
  3. LTA must submit an annual report to its supervising ministry. Correct answer.
  4. LTA submitted its report earlier than other statutory boards.

Explanation

The first statement applies the reporting requirement to every statutory board, and the second places LTA in that group. Therefore, LTA must submit an annual report to its supervising ministry; the statements do not say when it submitted or how others performed.

Question 20Verbal logic and argument evaluation

Five policy analysts (A, B, C, D, and E) are scheduled to present their papers at a seminar, one after another. The order must follow these constraints: 1. Analyst C must present immediately before E. 2. Analyst A cannot present first. 3. Analyst D must present third. 4. Analyst B must present last. Which of the following represents the correct sequence of presenters from first to last?

  1. C, E, D, A, B Correct answer.
  2. A, C, D, E, B
  3. E, C, D, A, B
  4. B, C, D, E, A

Explanation

Testing 'C, E, D, A, B': C is immediately before E (1st and 2nd) - valid. A is not first (A is 4th) - valid. D is third - valid. B is last (5th) - valid. All constraints are satisfied.

Question 21Verbal logic and argument evaluation

Consider the following facts: - Only senior officers or officers with specialized technical certifications are permitted to audit cybersecurity protocols. - Officer Lee does not hold a specialized technical certification. Based on the facts, which of the following is true?

  1. If Lee is a senior officer, Lee is permitted to audit cybersecurity protocols.
  2. Only senior officers are permitted to obtain specialized technical certifications.
  3. Lee is not permitted to audit cybersecurity protocols.
  4. If Lee is permitted to audit cybersecurity protocols, Lee must be a senior officer. Correct answer.

Explanation

Since Lee does not have the technical certification, the only other pathway for Lee to be permitted to audit protocols is if Lee is a senior officer. Thus, if Lee is permitted, Lee must be a senior officer.

Question 22Verbal logic and argument evaluation

For this exercise, a procurement policy states: 'Every evaluator must declare any real or perceived conflict of interest. An evaluator with a close personal relationship to a tenderer must recuse from the committee; declaring the relationship does not replace recusal.' Officer Tan declared that a tenderer is his first cousin but remained on the committee because he was the only technical expert available. Which option follows from the policy?

  1. The procurement is valid if Tan's evaluation scores are moderated by an independent auditor.
  2. Tan complied with the policy by declaring the relationship because of his technical expertise.
  3. Tan violated the policy because declaration does not waive the mandatory recusal requirement. Correct answer.
  4. Tan should have recused himself only if the tenderer reached the final shortlisting stage.

Explanation

The policy explicitly states that 'declaring a relationship does not substitute for recusal' and that officers with a close relationship 'must recuse themselves'. Tan's failure to recuse himself constitutes a policy violation.

Question 23Verbal logic and argument evaluation

A public housing developer stated: 'Due to rising material costs and supply chain constraints, all new Build-To-Order (BTO) housing projects launched this quarter will experience a delay of at least six months compared to their original target completion dates.' Which of the following, if true, most seriously weakens the developer's statement?

  1. The cost of construction labor has remained stable over the past twelve months.
  2. Two BTO projects launched last quarter were completed three months ahead of schedule.
  3. A new supply chain corridor opened this month, reducing the delivery time of key building materials by 30%.
  4. One BTO project launched this quarter is utilizing pre-fabricated materials sourced locally, bypassing supply chain constraints and meeting its original schedule. Correct answer.

Explanation

The developer's statement asserts that *all* BTO projects launched this quarter will experience a delay. Finding even one project launched this quarter that meets its original schedule directly contradicts and weakens the claim.

Question 24Verbal logic and argument evaluation

Identify the assumption required by the following argument: 'The agency will disable every clickable hyperlink in incoming email. This measure alone will prevent every successful email-borne compromise of the agency's network.'

  1. Every email-borne compromise requires a user to open a clickable hyperlink, and disabling those links cannot be bypassed. Correct answer.
  2. Disabling hyperlinks is the most cost-effective cybersecurity solution available.
  3. Public officers are unable to distinguish between legitimate and phishing hyperlinks.
  4. Disabling outgoing hyperlinks will not disrupt the daily administrative work of public officers.

Explanation

The conclusion claims that disabling links alone will prevent every email-borne compromise. That guarantee requires the assumption that attackers cannot succeed through another email mechanism, such as a malicious attachment or a QR code that leads users outside the email client.

Question 25Verbal logic and argument evaluation

Read the following statement: 'If the National Environment Agency (NEA) issues a heavy rain warning, the canal gates will be opened. If the canal gates are opened, low-lying areas will not flood. Today, the low-lying areas flooded.' Which of the following must be true?

  1. NEA issued a heavy rain warning, but the gates failed to open.
  2. The flooding was caused by a high tide rather than rainfall.
  3. The canal gates were opened today.
  4. NEA did not issue a heavy rain warning today. Correct answer.

Explanation

Using formal logic: Warning -> Gates Opened -> No Flood. Today, there was a flood. By contrapositive: Flood -> Gates Not Opened -> No Warning. Therefore, NEA did not issue a warning today.

Question 26Verbal logic and argument evaluation

Read the argument: 'Research shows that public park users who participate in community gardening schemes report a 25% higher rate of community belonging than those who do not. Therefore, expanding community gardening programs will directly increase social cohesion in residential estates.' Which of the following identifies a logical flaw in the argument?

  1. It assumes that a correlation between gardening and community belonging implies a causal relationship. Correct answer.
  2. It relies on self-reported data which is always inaccurate.
  3. It ignores the fact that some residents may prefer other outdoor activities like sports.
  4. It fails to consider the cost of building new gardening facilities in existing estates.

Explanation

The flaw is assuming correlation equals causation. People with a pre-existing strong sense of community belonging might simply be more likely to sign up for community gardening, meaning expanding the program might not cause belonging to rise in others.

Question 27Verbal logic and argument evaluation

For this exercise, an agency circular states: 'Every application for the Enterprise Support Grant must include a financial review from an independent firm. A start-up operating for less than 12 months must also submit a founder's declaration.' If an applicant did not submit a founder's declaration, which option is logically supported?

  1. The applicant company is not a startup entity.
  2. If the applicant company is a startup entity, its application is incomplete. Correct answer.
  3. The applicant company submitted only a third-party financial audit.
  4. The application will be rejected automatically.

Explanation

Startups are required to submit the founder's declaration. If the company is indeed a startup, failing to submit the declaration makes the application incomplete.

Question 28Verbal logic and argument evaluation

For this exercise, use the following municipal triage table: common property in a public housing estate goes to the Town Council; public roads or footpaths go to the Land Transport Authority (LTA); public parks or street trees go to the National Parks Board (NParks). A resident reports cracked concrete on a public footpath. Which body does the stated table assign as lead?

  1. National Parks Board (NParks)
  2. Municipal Services Office (MSO)
  3. Land Transport Authority (LTA) Correct answer.
  4. The local Town Council

Explanation

The primary asset involved is a public footpath. The passage states that if the feedback involves public roads or footpaths, LTA is assigned as the lead agency.

Question 29Verbal logic and argument evaluation

Consider the statement: 'If the Singapore dollar appreciates, imported raw materials become cheaper. If imported raw materials become cheaper, local manufacturing costs decrease. Local manufacturing costs did not decrease.' Which of the following is a logically valid conclusion?

  1. Exported goods became more expensive in the global market.
  2. Local manufacturing companies increased their profit margins.
  3. The Singapore dollar appreciated, but raw materials remained expensive due to high shipping rates.
  4. The Singapore dollar did not appreciate. Correct answer.

Explanation

Let P = SG dollar appreciates, Q = imported raw materials become cheaper, R = local manufacturing costs decrease. We have P -> Q, and Q -> R, which implies P -> R. Given not R (manufacturing costs did not decrease), by contrapositive, we must have not P (the Singapore dollar did not appreciate).

Question 30Verbal logic and argument evaluation

Four public communication campaigns (P, Q, R, and S) are launched by a ministry in different months of the year. The scheduling constraints are: 1. Campaign P must launch before Q. 2. Campaign R must launch in June. 3. Campaign S must launch immediately after Q. If Campaign Q is scheduled for August, in which month must Campaign S launch?

  1. October
  2. July
  3. May
  4. September Correct answer.

Explanation

The constraint states that 'Campaign S must launch immediately after Q'. Since Q launches in August, S must launch in the following month, which is September.

Question 31Verbal logic and argument evaluation

Evaluate the following argument: 'Government subsidies currently help keep public transport fares affordable. Therefore, any reduction in subsidies, however small, will make fares unaffordable.' Which option best identifies the logical gap?

  1. It assumes that any reduction must cross the affordability threshold, ignoring the size of the reduction and other cost or funding changes. Correct answer.
  2. It fails to define what constitutes an 'affordable' fare.
  3. It assumes that public transport operators are profit-driven.
  4. It assumes that reducing subsidies is the only way to fund transport improvements.

Explanation

Saying subsidies help affordability does not show that every reduction is large enough to make fares unaffordable. The conclusion also ignores possible offsets such as efficiency gains, other funding, or lower input costs; it therefore goes beyond the premise.

Question 32Verbal logic and argument evaluation

A hypothetical survey reports: 'Residents who volunteered had a median life-satisfaction score 15% higher than residents who did not. Therefore, encouraging more residents to volunteer will improve overall life satisfaction.' Which option identifies the most significant weakness in the conclusion?

  1. It assumes that volunteerism causes higher life satisfaction, rather than individuals with higher life satisfaction being more likely to volunteer. Correct answer.
  2. It relies on median scores rather than mean scores, which distort the true average.
  3. It fails to account for the impact of volunteerism on the target beneficiaries.
  4. It does not specify which types of volunteering activities (e.g., environmental, social service) were studied.

Explanation

The argument jumps from a correlation (volunteers have higher satisfaction) to a causal recommendation (volunteering will cause satisfaction to rise). It ignores the possibility of reverse causation.

Question 33Verbal logic and argument evaluation

Consider the statement: 'No temporary staff members are allowed to access the database. Some database-authorized individuals are not permanent employees.' If the statement is true, which of the following must also be true?

  1. Some permanent employees are database-authorized.
  2. All permanent employees are database-authorized.
  3. No temporary staff members are database-authorized. Correct answer.
  4. Some temporary staff members are database-authorized.

Explanation

Since 'No temporary staff members are allowed to access the database', it follows immediately that no temporary staff member can be database-authorized.

Question 34Verbal logic and argument evaluation

If a public sector project is delayed, the project manager must submit a deviation report. If a project manager submits a deviation report, the division director must review it. The division director did not review a deviation report from Manager Lee. What can be logically concluded?

  1. The division director deliberately chose not to review Lee's report.
  2. Manager Lee failed to submit a deviation report despite the project being delayed.
  3. Manager Lee's project was not delayed. Correct answer.
  4. The division director was on leave.

Explanation

Let D = delayed, R = report submitted, V = director reviews. The premises give D -> R and R -> V, so by transitivity D -> V. We are told not V (the director did not review). By contrapositive, not V forces not R, and not R forces not D. Therefore Manager Lee's project was not delayed.

Question 35Verbal logic and argument evaluation

For this exercise, a training agency's rule states: 'A provider may advertise a course as agency-subsidised only after the agency has issued written approval for that course.' Company Y advertised its course as agency-subsidised before receiving written approval. Which conclusion follows from the rule?

  1. Company Y's course will automatically be deregistered.
  2. Company Y must refund all course fees to registered applicants.
  3. Every applicant will lose any training credits already held.
  4. Company Y violated the stated advertising rule. Correct answer.

Explanation

The only stated condition for advertising a course as subsidised is prior written approval. Company Y advertised before that condition was met, so it violated the rule; the passage does not specify an automatic penalty.

Question 36Data interpretation and quantitative foundations

A government department's expenditure on IT maintenance increased from S$1.2 million in 2023 to S$1.5 million in 2024. What was the percentage increase in expenditure?

  1. 20%
  2. 25% Correct answer.
  3. 15%
  4. 30%

Explanation

Percentage increase = (New Value - Old Value) / Old Value = (1.5 - 1.2) / 1.2 = 0.3 / 1.2 = 0.25, which is 25%.

Question 37Data interpretation and quantitative foundations

The table below shows the annual budget allocations (in S$ Millions) for three public health programs over three years: | Program | Year 1 | Year 2 | Year 3 | |---|---|---|---| | Disease Prevention | 40 | 50 | 60 | | Healthy Eating | 20 | 25 | 35 | | Active Aging | 30 | 45 | 40 | What was the percentage increase in the total budget allocated to all three programs from Year 1 to Year 3?

  1. 50% Correct answer.
  2. 60%
  3. 40%
  4. 33.3%

Explanation

Total Year 1 budget = 40 + 20 + 30 = S$90 Million. Total Year 3 budget = 60 + 35 + 40 = S$135 Million. Percentage increase = (135 - 90) / 90 = 45 / 90 = 0.50, which is 50%.

Question 38Data interpretation and quantitative foundations

In 2026, a Singapore Citizen employee aged 55 or below earns S$6,000 in ordinary wages for the month, with no additional wages. The applicable CPF rates are 20% from the employee and 17% from the employer. What is the total monthly CPF contribution credited to the employee's accounts?

  1. S$2,220 Correct answer.
  2. S$1,020
  3. S$1,200
  4. S$2,000

Explanation

For an employee aged 55 or below earning more than S$750, the stated 2026 rates total 37%. Because S$6,000 is within the applicable ordinary-wage ceiling, the contribution is 0.37 × S$6,000 = S$2,220.

Question 39Data interpretation and quantitative foundations

In a simplified planning model, 3 survey teams can complete observations at 15 bus stops in 45 minutes. At the same constant rate per team, what is the maximum number of whole stops that 5 teams can complete in 60 minutes?

  1. 20 stops
  2. 25 stops
  3. 33 stops Correct answer.
  4. 30 stops

Explanation

The first scenario uses 3 × 45 = 135 team-minutes for 15 stops, or 9 team-minutes per stop. Five teams provide 5 × 60 = 300 team-minutes; 300 ÷ 9 = 33⅓, so they can complete 33 whole stops, with insufficient time to finish a 34th.

Question 40Data interpretation and quantitative foundations

Singapore's resident unemployment rate was 2.8% in Quarter 1. In Quarter 2, the number of unemployed residents increased by 10%, while the total resident labor force remained constant. What was the resident unemployment rate in Quarter 2?

  1. 2.9%
  2. 3.08% Correct answer.
  3. 3.8%
  4. 3.1%

Explanation

Let the total resident labor force be L. The number of unemployed in Q1 is 0.028 * L. In Q2, the number of unemployed increases by 10%, so it becomes 1.10 * 0.028 * L = 0.0308 * L. Since L is constant, the new unemployment rate is 3.08%.

Question 41Data interpretation and quantitative foundations

A water conservation project aims to reduce daily household water consumption. In a study of 1,200 households: - 60% of households installed water-saving showerheads. - 40% of the households that installed water-saving showerheads also installed dual-flush toilets. How many households in the study installed both water-saving devices?

  1. 192
  2. 288 Correct answer.
  3. 720
  4. 480

Explanation

Households with showerheads = 60% of 1,200 = 0.60 * 1200 = 720. Households with both = 40% of 720 = 0.40 * 720 = 288.

Question 42Data interpretation and quantitative foundations

A qualifying Singapore start-up is in one of its first three consecutive Years of Assessment and has S$150,000 of normal chargeable income. Apply the 17% corporate tax rate and the start-up exemption: 75% of the first S$100,000 is exempt and 50% of the next S$100,000 is exempt. Ignoring any separate rebate, what tax is payable?

  1. S$8,500 Correct answer.
  2. S$25,500
  3. S$9,562.50
  4. S$7,225

Explanation

Normal chargeable income = S$150,000. First S$100,000: 75% exempt, so taxable portion is 25% of S$100,000 = S$25,000. Next S$50,000: 50% exempt, so taxable portion is 50% of S$50,000 = S$25,000. Total taxable income = S$25,000 + S$25,000 = S$50,000. Tax payable = 17% of S$50,000 = 0.17 * 50000 = S$8,500.

Question 43Data interpretation and quantitative foundations

A public project has a total budget of S$5,000,000. It is allocated as follows: 50% for civil construction, 30% for mechanical works, and 20% for electrical works. During execution, construction costs overrun by 10%, while mechanical works are completed 10% under budget. Assuming electrical works stay exactly on budget, what is the net overrun or underrun for the entire project?

  1. Net overrun of S$250,000
  2. Net underrun of S$100,000
  3. Net overrun of S$100,000 Correct answer.
  4. Project remains exactly on budget

Explanation

Allocations: - Civil Construction: 50% of S$5,000,000 = S$2,500,000. - Mechanical: 30% of S$5,000,000 = S$1,500,000. - Electrical: 20% of S$5,000,000 = S$1,000,000. Changes: - Construction overrun = +10% of S$2,500,000 = +S$250,000. - Mechanical underrun = -10% of S$1,500,000 = -S$150,000. Net change = +S$250,000 - S$150,000 = +S$100,000. This is a net overrun of S$100,000.

Question 44Data interpretation and quantitative foundations

The daily passenger volume of a MRT station is 80,000 on weekdays and decreases by 30% on weekends. What is the total weekly passenger volume for this MRT station, assuming 5 weekdays and 2 weekend days?

  1. 400,000
  2. 560,000
  3. 512,000 Correct answer.
  4. 480,000

Explanation

Weekday volume = 80,000. Total weekdays = 5 * 80,000 = 400,000. Weekend volume = 80,000 * 0.70 = 56,000. Total weekend days = 2 * 56,000 = 112,000. Total weekly volume = 400,000 + 112,000 = 512,000.

Question 45Data interpretation and quantitative foundations

A local community center offers language courses. The ratio of students enrolled in Mandarin, Malay, and Tamil is 5:3:2. If there are 120 students enrolled in the Malay course, what is the total number of students enrolled in all three language courses?

  1. 300 students
  2. 200 students
  3. 240 students
  4. 400 students Correct answer.

Explanation

The ratio is 5 (Mandarin) : 3 (Malay) : 2 (Tamil). Malay represents 3 parts of the total 10 parts (5+3+2 = 10). Since 3 parts = 120 students, 1 part = 40 students. Total students = 10 parts * 40 students/part = 400 students.

Question 46Data interpretation and quantitative foundations

An administrative division processes digital permit applications. Team A can process 200 applications in 8 hours. Team B can process 200 applications in 5 hours. If both teams work together, how many hours will it take them to process a batch of 520 applications?

  1. 10 hours
  2. 6.5 hours
  3. 8 hours Correct answer.
  4. 5.5 hours

Explanation

Find the hourly rates: - Team A rate = 200 / 8 = 25 applications/hour. - Team B rate = 200 / 5 = 40 applications/hour. Combined rate = 25 + 40 = 65 applications/hour. Time to process 520 applications = 520 / 65 = 8 hours.

Question 47Data interpretation and quantitative foundations

A public housing estate has a mix of 3-room, 4-room, and 5-room flats. The ratio of 3-room to 4-room flats is 2:3, and the ratio of 4-room to 5-room flats is 4:3. If there are 360 5-room flats in the estate, how many 3-room flats are there?

  1. 480
  2. 320 Correct answer.
  3. 180
  4. 240

Explanation

Let's find the joint ratio: 3-room : 4-room = 2:3 = 8:12. 4-room : 5-room = 4:3 = 12:9. So the combined ratio of 3-room : 4-room : 5-room is 8:12:9. Given 5-room flats = 360, which corresponds to 9 parts. So 1 part = 360 / 9 = 40 flats. Number of 3-room flats (8 parts) = 8 * 40 = 320 flats.

Question 48Data interpretation and quantitative foundations

A policy research department conducted a survey on transport usage. Out of 1,500 respondents, 70% use the MRT daily, 50% use the public bus daily, and 30% use both daily. How many respondents use neither transport mode daily?

  1. 450
  2. 100
  3. 300
  4. 150 Correct answer.

Explanation

Using the principle of inclusion-exclusion: % using MRT or Bus = % MRT + % Bus - % Both = 70% + 50% - 30% = 90%. % using neither = 100% - 90% = 10%. Number of respondents using neither = 10% of 1,500 = 150.

Question 49Data interpretation and quantitative foundations

In a municipal region, the volume of waste recycled in 2024 was 4,200 tonnes, which represents a 20% increase from the volume recycled in 2023. What was the volume of waste recycled in 2023?

  1. 3,800 tonnes
  2. 3,600 tonnes
  3. 3,360 tonnes
  4. 3,500 tonnes Correct answer.

Explanation

Let the 2023 volume be X. Volume in 2024 = 1.20 * X = 4,200. X = 4,200 / 1.20 = 3,500 tonnes.

Question 50Data interpretation and quantitative foundations

The government plans to distribute GST vouchers to citizens based on their household income. If the budget allocation is S$120 Million for lower-income households and S$80 Million for middle-income households, what percentage of the total budget is allocated to lower-income households?

  1. 40%
  2. 66.7%
  3. 60% Correct answer.
  4. 75%

Explanation

Total budget = S$120M + S$80M = S$200M. Lower-income allocation percentage = S$120M / S$200M = 0.60, which is 60%.
