Question 1Verbal Reasoning

Choose the word that is closest in meaning to "brief".

  1. short Correct answer.
  2. rare
  3. loud
  4. angry

Explanation

"Brief" describes something lasting only a short time or expressed in few words, so "short" captures its core meaning. The other words describe emotions, volume, or frequency rather than duration or length.

Question 2Verbal Reasoning

Choose the word that is most nearly opposite in meaning to "expand".

  1. contract Correct answer.
  2. inflate
  3. extend
  4. stretch

Explanation

To expand is to grow larger or take up more space; its opposite is to grow smaller, which "contract" expresses. The other three options all describe increasing size and are therefore synonyms of expand rather than opposites.

Question 3Verbal Reasoning

Read the sentence: "The hikers reached the summit at dawn, exhausted but triumphant." Which word best describes how the hikers felt?

  1. indifferent
  2. defeated
  3. victorious Correct answer.
  4. frightened

Explanation

"Triumphant" means having achieved victory or success, which is the meaning of "victorious." The sentence states they succeeded despite tiredness, so the feeling is positive and proud.

Question 4Verbal Reasoning

Which sentence is written correctly?

  1. They're going to the meeting later. Correct answer.
  2. Their going to the meeting later.
  3. Theyre going to the meeting later.
  4. There going to the meeting later.

Explanation

"They're" is the contraction of "they are," which fits the sentence's need for a subject and verb. "Their" is possessive, "there" refers to place, and "theyre" lacks the required apostrophe.

Question 5Verbal Reasoning

A passage states: "Regular exercise improves heart health. It also reduces stress and improves sleep quality." What is the main idea of the passage?

  1. Exercise benefits both body and mind. Correct answer.
  2. Sleep is more important than exercise.
  3. Stress causes poor sleep.
  4. Exercise is only useful for the heart.

Explanation

The passage lists physical benefit (heart health) and mental or lifestyle benefits (lower stress, better sleep), so the main idea is that exercise helps body and mind together. The other options either narrow the claim or introduce relationships the passage does not state.

Question 6Verbal Reasoning

Choose the correctly spelled word to complete the sentence: "She gave a clear ___ of the plan."

  1. explanation Correct answer.
  2. explaination
  3. explanetion
  4. explanasion

Explanation

The noun formed from "explain" is "explanation," which drops the "i" from the verb stem. The other spellings insert letters that do not appear in the standard form.

Question 7Verbal Reasoning

Which word best completes the sentence? "The instructions were so ___ that everyone understood them immediately."

  1. lengthy
  2. vague
  3. clear Correct answer.
  4. complex

Explanation

The result clause "everyone understood them immediately" signals that the instructions were easy to grasp, which "clear" expresses. The other adjectives would produce a contradiction with that result.

Question 8Verbal Reasoning

In the sentence "The manager, who had reviewed the report, approved the budget," what does the clause "who had reviewed the report" do?

  1. It adds descriptive information about the manager. Correct answer.
  2. It asks a question about the manager.
  3. It gives the reason the budget was approved.
  4. It states the main action of the sentence.

Explanation

The clause is set off by commas and begins with the relative pronoun "who," so it functions as a non-essential description of the manager. The main action of the sentence is "approved the budget."

Question 9Verbal Reasoning

A memo reads: "All staff must submit timesheets by Friday. Late submissions will delay payroll." What is the purpose of the second sentence?

  1. To explain a consequence of missing the deadline Correct answer.
  2. To request that payroll staff work late
  3. To introduce a new deadline for payroll
  4. To describe how to fill in a timesheet

Explanation

The second sentence links late timesheets to delayed pay, which is a consequence of failing to meet the Friday deadline. It does not give instructions or set a new deadline.

Question 10Verbal Reasoning

Choose the word that best completes the analogy: "Author is to book as composer is to ___."

  1. instrument
  2. orchestra
  3. symphony Correct answer.
  4. concert

Explanation

An author creates a book, so the second term should be the work a composer creates, which is a symphony. The other options are performers, tools, or events rather than the created work.

Question 11Verbal Reasoning

Read the passage: "Although the new policy was popular with employees, it increased administrative costs by 20 percent. Management therefore decided to revise it after six months." Why did management decide to revise the policy?

  1. Six months had passed since it was written.
  2. Employees disliked the policy.
  3. The policy had never been implemented.
  4. Administrative costs rose significantly. Correct answer.

Explanation

The word "therefore" signals that the revision follows from the stated cause: a 20 percent rise in administrative costs. The passage explicitly says the policy was popular with employees, ruling out that reason.

Question 12Verbal Reasoning

Which sentence uses the semicolon correctly?

  1. She brought; a notebook and a pen.
  2. The rain stopped; we continued the hike. Correct answer.
  3. I wanted to attend; but the meeting ran late.
  4. Although it was late; we kept working.

Explanation

A semicolon joins two independent clauses without a conjunction, and "The rain stopped" and "we continued the hike" are both complete clauses. The other sentences misuse it before a conjunction, mid-list, or after a subordinate clause.

Question 13Verbal Reasoning

Choose the word that best completes the sentence: "The evidence was ___; it convinced even the most skeptical reviewers."

  1. tentative
  2. irrelevant
  3. ambiguous
  4. compelling Correct answer.

Explanation

The clause after the semicolon shows the evidence persuaded skeptics, so it must have been strong and convincing, which "compelling" means. The other adjectives describe weak or unclear evidence that would not persuade.

Question 14Verbal Reasoning

Read the passage: "The company's profits rose sharply last quarter. However, analysts noted that most of the gain came from a one-time sale of a building rather than from ordinary operations." What do the analysts imply?

  1. The building was sold at a loss.
  2. The profit increase may not reflect lasting performance. Correct answer.
  3. The company is likely to keep growing at the same rate.
  4. Ordinary operations were unusually strong.

Explanation

By attributing the gain to a one-time sale rather than ordinary operations, the analysts suggest the rise is not a reliable sign of ongoing performance. The contrast word "However" signals this caution.

Question 15Verbal Reasoning

Which sentence is grammatically correct?

  1. Neither of the candidates were submitting a form.
  2. Neither of the candidates has submitted a form. Correct answer.
  3. Neither of the candidates have submitted a form.
  4. Neither of the candidates having submitted a form.

Explanation

"Neither" is singular, so its verb should be singular: "has submitted." The plural verb forms and the participle construction do not agree with the singular subject.

Question 16Verbal Reasoning

A notice reads: "Employees who wish to work from home on Fridays must obtain approval from their supervisor at least two days in advance." What must an employee do to work from home on a Friday?

  1. Inform a colleague two days beforehand.
  2. Work from home every Friday without approval.
  3. Submit a written request on the Friday morning.
  4. Get supervisor approval two days ahead. Correct answer.

Explanation

The notice requires supervisor approval obtained at least two days before the Friday. The other options either name the wrong person, the wrong timing, or ignore the approval requirement.

Question 17Verbal Reasoning

Choose the word closest in meaning to "meticulous".

  1. hurried
  2. doubtful
  3. careless
  4. thorough Correct answer.

Explanation

"Meticulous" describes someone who pays great attention to detail, which "thorough" captures. The other options describe a lack of care or certainty rather than careful precision.

Question 18Verbal Reasoning

Which revision best combines these sentences without changing the meaning? "The train was delayed. We missed the concert."

  1. The train was delayed, but we missed the concert.
  2. The train was delayed, or we missed the concert.
  3. Although the train was delayed, we missed the concert.
  4. The train was delayed, so we missed the concert. Correct answer.

Explanation

The delay caused the missed concert, so a cause-and-effect connector such as "so" preserves the meaning. The other connectors signal contrast or alternatives that misrepresent the relationship.

Question 19Verbal Reasoning

Read the passage: "Critics praised the film's cinematography, yet audiences found the plot confusing. The studio, hoping for broad appeal, now plans a shorter re-edit." Which statement is best supported?

  1. Critics disliked the cinematography.
  2. The re-edit will remove the cinematography.
  3. The studio is responding to audience concerns. Correct answer.
  4. The film succeeded with audiences.

Explanation

The studio's plan for a shorter re-edit follows the report that audiences found the plot confusing, showing a response to that concern. The passage does not support the other claims.

Question 20Verbal Reasoning

Which word best completes the sentence? "The witness's account was so ___ that investigators could not determine what had happened."

  1. incoherent Correct answer.
  2. consistent
  3. detailed
  4. precise

Explanation

If investigators could not determine what happened, the account must have been unclear or disjointed, which "incoherent" means. Precise, consistent, and detailed accounts would aid rather than block understanding.

Question 21Verbal Reasoning

Read the passage: "The city's bike-share program doubled its ridership in one year. Officials credit new docking stations near transit hubs, though some residents say mild weather was the real cause." Which claim is presented as the officials' view?

  1. The program lost riders over the year.
  2. Transit hubs should be closed.
  3. New docking stations caused the increase. Correct answer.
  4. Mild weather caused the increase.

Explanation

The passage states that officials credit new docking stations near transit hubs for the growth. The weather explanation is attributed to some residents, not officials.

Question 22Verbal Reasoning

Read the passage: "The proposal to widen the highway promised faster commutes. Yet the town council rejected it, citing the loss of parkland and the cost of maintenance." What is the council's reasoning?

  1. The highway is already wide enough.
  2. Maintenance costs would decrease after widening.
  3. Faster commutes are unimportant to residents.
  4. The benefits do not outweigh the environmental and financial costs. Correct answer.

Explanation

The council weighed the promised benefit against parkland loss and maintenance costs and rejected the plan, implying the drawbacks outweighed the benefits. The passage does not claim commutes are unimportant or that the road is wide enough.

Question 23Verbal Reasoning

Read the passage: "Some argue that remote work reduces productivity because employees are less supervised. However, studies comparing output before and after remote arrangements found no decline. The supervision argument therefore rests on an assumption that output requires constant oversight." What is the author doing in the final sentence?

  1. Agreeing that remote work reduces productivity.
  2. Providing new data about productivity.
  3. Identifying an unstated assumption in the opposing argument. Correct answer.
  4. Describing how remote arrangements are supervised.

Explanation

The final sentence names the hidden premise the supervision argument depends on: that output needs constant oversight. This is an analysis of the argument's assumption, not new evidence or agreement.

Question 24Verbal Reasoning

Read the passage: "The museum's attendance fell after it introduced ticket fees. It concluded that fees deter visitors and plans to abolish them. But attendance also fell at free museums nearby that same season, suggesting other factors were at work." Which statement weakens the museum's conclusion?

  1. The museum introduced ticket fees.
  2. Attendance fell at nearby free museums too. Correct answer.
  3. Attendance fell after the fees began.
  4. The museum plans to abolish the fees.

Explanation

If free museums also saw attendance drop, a common outside factor may explain the decline, undermining the claim that fees caused it. The other statements merely restate the museum's evidence or plan.

Question 25Verbal Reasoning

Read the passage: "Although the report acknowledged gaps in the data, its recommendations were presented as definitive. Reviewers objected less to the substance than to this mismatch between evidence and tone." What did the reviewers mainly object to?

  1. The confident tone not matched by the evidence. Correct answer.
  2. The length of the report.
  3. The report's underlying data set.
  4. The absence of any recommendations.

Explanation

The passage states reviewers objected to the mismatch between acknowledged data gaps and definitive-sounding recommendations, which is a problem of tone versus evidence. It explicitly says their objection was not mainly about substance.

Question 26Verbal Reasoning

Choose the correctly spelled word to complete the sentence: "The committee reached a ___ decision after lengthy debate."

  1. unanimous Correct answer.
  2. unanimus
  3. unanimious
  4. unamimous

Explanation

The correct spelling is 'unanimous', from Latin 'unanimus' (one mind). The other options contain common misspellings with incorrect vowel or consonant patterns.

Question 27Verbal Reasoning

Choose the word that best completes the analogy: "Doctor is to hospital as teacher is to ___"

  1. student
  2. school Correct answer.
  3. book
  4. lesson

Explanation

The relationship is between a professional and their primary workplace. A doctor works in a hospital, so a teacher works in a school.

Question 28Verbal Reasoning

Which sentence uses the colon correctly?

  1. She brought three: items a pen, a notebook, and a calculator.
  2. She brought: three items, a pen, a notebook, and a calculator.
  3. She brought three items: a pen, a notebook, and a calculator. Correct answer.
  4. She brought three items, a pen, a notebook, and a calculator:.

Explanation

A colon is used after a complete independent clause to introduce a list. Only the first option places the colon after the complete clause 'She brought three items' and before the list.

Question 29Verbal Reasoning

Read the passage: "The new software reduced processing time by 30 percent. However, the training required to use it took two full weeks, during which productivity dropped. Management concluded that the software was a success." Which assumption best supports management's conclusion?

  1. Employees preferred the new software to the old system.
  2. The long-term gains from reduced processing time outweigh the short-term productivity loss. Correct answer.
  3. The training period was shorter than expected.
  4. Processing time is the only metric that matters.

Explanation

The conclusion that the software is a success despite a temporary productivity drop assumes that the lasting benefit of faster processing exceeds the one-time cost of training.

Question 30Verbal Reasoning

Read the passage: "The city's recycling rate increased after curbside pickup was expanded to include glass and plastics. However, the overall tonnage of waste sent to landfills remained unchanged." Which statement is best supported by the passage?

  1. Residents recycled less glass and plastic than before.
  2. More materials were recycled, but total waste generation may have increased. Correct answer.
  3. The expansion of curbside pickup caused an increase in total waste.
  4. Landfill tonnage is the only measure of recycling success.

Explanation

If recycling increased while landfill tonnage stayed the same, total waste generated likely rose, since recycled and landfilled amounts together make up total waste.

Question 31Verbal Reasoning

Read the passage: "The author argues that standardized tests should be abolished because they fail to measure creativity. Yet the author offers no evidence that creativity is a goal of the tests." Which criticism of the author's argument is made in the passage?

  1. The argument generalizes from a small sample.
  2. The argument attacks a position the author does not hold.
  3. The argument assumes what it sets out to prove.
  4. The argument relies on an irrelevant criterion. Correct answer.

Explanation

The passage points out that creativity may not be a purpose of the tests, so judging them by that standard is irrelevant to their intended function.

Question 32Verbal Reasoning

Which sentence is most concise without changing the meaning?

  1. Owing to the fact that it was raining, the event was cancelled.
  2. Because it was raining, the event was cancelled. Correct answer.
  3. Due to the fact that it was raining, the event was cancelled.
  4. The event was cancelled because of the fact that it was raining.

Explanation

The phrase 'because it was raining' conveys the same causal meaning as the wordier alternatives, which use unnecessary padding such as 'due to the fact that'.

Question 33Verbal Reasoning

Choose the word that best completes the sentence: "The professor's explanation was so ___ that even the complex theory seemed simple."

  1. opaque
  2. verbose
  3. lucid Correct answer.
  4. tedious

Explanation

The sentence implies clarity: a good explanation makes a complex topic seem simple. 'Lucid' means clear and easy to understand.

Question 34Verbal Reasoning

Read the passage: "Although the museum's new exhibit was criticized for lacking historical context, it attracted record numbers of visitors. The museum's director argued that the exhibit's popularity justified its approach." Which is the strongest counterargument to the director's claim?

  1. The exhibit was criticized by historians.
  2. The museum should focus on historical accuracy.
  3. Record visitor numbers may be due to other factors.
  4. Popularity does not necessarily indicate educational value. Correct answer.

Explanation

The director equates popularity with justification. The strongest counterargument challenges that assumption by pointing out that high attendance does not prove educational merit.

Question 35Verbal Reasoning

Read the passage: "The company's new policy requires all employees to use a single communication platform. Previously, teams used various tools, which led to duplicated messages and missed updates. The policy aims to streamline communication." Which is the most reasonable inference?

  1. The old tools were completely ineffective.
  2. Employees will resist the new policy.
  3. The new platform will eliminate all communication problems.
  4. The company values efficiency over flexibility in communication tools. Correct answer.

Explanation

The passage states the policy aims to streamline communication by eliminating duplication and missed updates, implying a preference for efficiency over flexibility.

Question 36Verbal Reasoning

Which sentence uses the apostrophe correctly?

  1. The dog's' bone was buried in the yard.
  2. The dog's bone was buried in the yard. Correct answer.
  3. The dogs bone was buried in the yard.
  4. The dogs' bone was buried in the yard.

Explanation

The apostrophe in 'dog's' correctly indicates possession for a singular noun. The other options either omit the apostrophe or place it incorrectly.

Question 37Verbal Reasoning

Read the passage: "The study found that students who ate breakfast scored higher on tests. It concluded that eating breakfast improves test performance. However, the study did not account for students' overall diet or sleep habits." Which flaw is identified in the passage?

  1. The study confuses correlation with causation. Correct answer.
  2. The study's sample was too small.
  3. The study was not peer-reviewed.
  4. The study relies on self-reported data.

Explanation

The passage notes that the study did not control for other factors such as diet and sleep, which means the observed correlation may not imply that breakfast causes higher scores.

Question 38Verbal Reasoning

Read the passage: "The proposal to ban plastic bags was rejected because it would harm small businesses. Yet the evidence for harm came solely from a survey conducted by an industry group that opposes the ban." Which statement best evaluates the evidence?

  1. The evidence is strong because it comes from businesses.
  2. The evidence is invalid because surveys cannot measure economic impact.
  3. The evidence is potentially biased because its source has a vested interest. Correct answer.
  4. The evidence is irrelevant because the ban was already rejected.

Explanation

The passage highlights that the survey was conducted by an industry group that opposes the ban, suggesting a conflict of interest that could bias the results.

Question 39Verbal Reasoning

Read the passage: "The author claims that because the novel sold millions of copies, it must be of high literary quality. This reasoning overlooks the fact that popular appeal and literary merit are not always aligned." Which logical error is described?

  1. Ad hominem
  2. Appeal to popularity Correct answer.
  3. False dilemma
  4. Slippery slope

Explanation

The author equates widespread popularity with quality, which is the appeal to popularity fallacy. The passage explicitly notes that popular appeal and literary merit are not always aligned.

Question 40Verbal Reasoning

Read the passage: "The team's lead engineer insisted that the prototype was ready for testing. Two of her colleagues privately noted that the safety checks had been rushed and that the sensor calibration was incomplete. When the prototype failed during the first trial, the engineer blamed faulty components rather than the schedule." Which statement is best supported by the passage?

  1. The engineer's confidence was not fully shared by her colleagues, who had concerns about the testing process. Correct answer.
  2. The colleagues believed the prototype should never have been built.
  3. The prototype failed because the components supplied to the team were defective.
  4. The engineer accepted that the rushed schedule had caused the failure.

Explanation

The passage states that two colleagues privately noted rushed safety checks and incomplete calibration, which shows their confidence was lower than the engineer's. The engineer's own explanation (faulty components) is her claim, not a fact the passage establishes. Inference questions require choosing only what the text supports, not what a character asserts.

Question 41Numerical Reasoning

A store sells a jacket for £80. The price is reduced by 15%. What is the new price?

  1. £65
  2. £68 Correct answer.
  3. £12
  4. £72

Explanation

A 15% reduction means the customer pays 85% of the original price. Multiplying £80 by 0.85 gives £68. Subtracting 15% of £80 (£12) from £80 confirms the same result.

Question 42Numerical Reasoning

A train travels 240 km in 3 hours. What is its average speed in km/h?

  1. 60
  2. 720
  3. 120
  4. 80 Correct answer.

Explanation

Average speed equals distance divided by time. Dividing 240 km by 3 hours gives 80 km/h. Checking by multiplying 80 by 3 returns the original distance of 240 km.

Question 43Numerical Reasoning

What is the next number in the sequence 3, 6, 12, 24, ...?

  1. 48 Correct answer.
  2. 36
  3. 27
  4. 30

Explanation

Each term is double the previous term, so the pattern is multiplication by 2. Doubling 24 gives 48. The differences (3, 6, 12) also double, confirming the rule.

Question 44Numerical Reasoning

A team of 4 workers builds a wall in 9 days. Working at the same rate, how long would 6 workers take?

  1. 7 days
  2. 6 days Correct answer.
  3. 13.5 days
  4. 4.5 days

Explanation

The total work is 4 × 9 = 36 worker-days. Dividing 36 worker-days by 6 workers gives 6 days. More workers means proportionally fewer days, so the answer must be less than 9.

Question 45Numerical Reasoning

Which of these numbers is largest?

  1. 0.099
  2. 0.7
  3. 0.8 Correct answer.
  4. 0.65

Explanation

Compare digits from left to right after the decimal point. 0.8 has 8 tenths, which exceeds 7 tenths, 6 tenths and 0 tenths. Therefore 0.8 is the largest value.

Question 46Numerical Reasoning

A shirt costs £40 and is increased in price by 25%. What is the new price?

  1. £65
  2. £45
  3. £50 Correct answer.
  4. £10

Explanation

A 25% increase adds a quarter of the original price. A quarter of £40 is £10, and £40 + £10 = £50. Equivalently, multiply £40 by 1.25 to get £50.

Question 47Numerical Reasoning

What is 3/4 expressed as a percentage?

  1. 0.75%
  2. 75% Correct answer.
  3. 43%
  4. 34%

Explanation

To convert a fraction to a percentage, divide the numerator by the denominator and multiply by 100. 3 ÷ 4 = 0.75, and 0.75 × 100 = 75%.

Question 48Numerical Reasoning

A bag contains 5 red and 15 blue counters. What fraction of the counters are red?

  1. 3/4
  2. 1/3
  3. 5/15
  4. 1/4 Correct answer.

Explanation

The total number of counters is 5 + 15 = 20. The red fraction is 5/20, which simplifies to 1/4.

Question 49Numerical Reasoning

A recipe uses 200 g of flour to make 8 cakes. How much flour is needed for 20 cakes?

  1. 400 g
  2. 500 g Correct answer.
  3. 450 g
  4. 520 g

Explanation

Find the flour per cake by dividing 200 g by 8, giving 25 g per cake. Multiplying 25 g by 20 cakes gives 500 g.

Question 50Numerical Reasoning

A car uses 6 litres of fuel to travel 90 km. How many litres are needed for 150 km at the same rate?

  1. 10 Correct answer.
  2. 12
  3. 11
  4. 9

Explanation

Fuel per kilometre is 6 ÷ 90 = 1/15 litre. Multiplying by 150 km gives 10 litres. Checking, 10 litres is 150/15, consistent with the ratio.
