Question 1Meaning, paragraph organization and warranted inference

Fill in the blanks with the most appropriate words: 在推进全面依法治国的进程中，公安机关必须坚持______执法与______执法相统一，既要铁腕惩治违法犯罪，又要让人民群众在每一起案件办理中感受到公平正义。

  1. 严格；规范 Correct answer.
  2. 粗放；随意
  3. 盲目；被动
  4. 机械；片面

Explanation

In standard Chinese public security legal doctrine, law enforcement must adhere to '严格规范公正文明执法' (strict, standardized, fair, and civilized law enforcement). '严格' (strict) and '规范' (standardized) form the canonical collocations reflecting rigorous enforcement balanced with standardized due process.

Question 2Meaning, paragraph organization and warranted inference

Fill in the blank with the most accurate idiom: 在新型网络电信诈骗案件的侦办过程中，犯罪分子藏匿于境外服务器之后，侦查员面对海量碎片化数据，必须善于从______中寻找关键线索，循线深挖，彻底捣毁黑灰产链条。

  1. 蛛丝马迹 Correct answer.
  2. 捕风捉影
  3. 信口开河
  4. 海市蜃楼

Explanation

'蛛丝马迹' (subtle clues / faint traces) metaphorically describes tiny, hidden leads that detectives uncover from vast data streams to solve complex crimes. It fits the investigative context perfectly.

Question 3Meaning, paragraph organization and warranted inference

Which of the following police incident bulletins (警情通报) adheres best to the principles of objective factual description, authoritative precision, and proper legal moderation?

  1. 2026年3月5日14时许，我局接群众报警称某商场发生持刀伤人事件。民警迅速到场处置，当场控制嫌疑人张某（男，32岁），并将2名伤者送医救治（生命体征平稳）。目前案件正在进一步侦办中。 Correct answer.
  2. 今天下午商场发生极其恶劣的杀人案，凶手手段残忍令人发指，大家千万不要出门，凶手同伙可能还在附近潜伏！
  3. 商场好像有人打架，具体情况我们也不太清楚，请广大市民自行看网上传播的视频辨别真伪。
  4. 重大突发！某商场血流成河，警方虽然抓了人，但案件内幕极其复杂，涉及惊天大阴谋。

Explanation

The standard public security incident bulletin citing the verified timestamp, on-scene police control of suspect Zhang, medical treatment of the two victims, and ongoing investigation adheres strictly to official press release guidelines: precise time, prompt response, verified suspect demographics, objective description of injuries, and formal legal status without subjective sensationalism or alarmism.

Question 4Meaning, paragraph organization and warranted inference

Read the following passage and identify its central thesis: 警务大数据的核心价值不仅在于海量数据的汇聚，更在于算法模型对实战业务的精准赋能。如果脱离了基层实战需求，数据就会成为沉睡的‘数字孤岛’；只有将情报研判深度嵌入指挥调度、侦查破案、基础防范的每一个实战节点，才能真正实现由‘汗水警务’向‘智慧警务’的跨越。 What is the main argument of this passage?

  1. Big data technology must be deeply integrated with grassroots frontline policing needs to achieve genuine smart policing. Correct answer.
  2. Public security organs should completely stop collecting large datasets and return to traditional patrol methods.
  3. Grassroots police officers are not capable of understanding digital algorithms.
  4. Procuring the most expensive server hardware is the only metric for public security modernization.

Explanation

The passage emphasizes that big data must not remain idle ('数字孤岛') but must be deeply embedded into operational grassroots policing (指挥调度、侦查破案、基础防范) to transition from sweat-based policing to smart policing.

Question 5Meaning, paragraph organization and warranted inference

Arrange the following sentences into a logically coherent narrative of an emergency 110 call dispatch sequence: ① 110指挥中心接报警称某小区发生入室盗窃 ② 综合指挥室通过对讲机指令距离案发地最近的巡逻车前往处置 ③ 现场民警将嫌疑人移交辖区派出所作进一步审查 ④ 处警民警3分钟内赶赴现场并将企图逃跑的嫌疑人当场抓获 ⑤ 接警员快速记录案发详细地址、嫌疑人特征并一键派发警情 What is the correct logical order?

  1. ①-⑤-②-④-③ Correct answer.
  2. ①-②-⑤-③-④
  3. ⑤-①-④-②-③
  4. ②-①-⑤-④-③

Explanation

The chronological sequence of emergency dispatch is: (1) Initial call received (①) → (2) Call-taker logs details and dispatches incident digitally (⑤) → (3) Command center orders nearest patrol car via radio (②) → (4) Patrol arrives within 3 min and apprehends suspect (④) → (5) Suspect transferred to local precinct for investigation (③). This corresponds to ①-⑤-②-④-③.

Question 6Meaning, paragraph organization and warranted inference

Read the following text and determine the author's primary attitude towards community dispute mediation: 社区民警在日常走访中，必须把‘情、理、法’有机融合。法律是硬性的准绳，但在邻里纠纷、家庭矛盾等微观社会冲突中，如果单纯依赖僵硬的法条裁决，往往‘案结事不了’，甚至埋下激化的隐患。唯有耐心倾听诉求，用真情化解心结，用法治讲明利害，方能实现‘案结事了人和’。 What does the author advocate?

  1. Community officers must combine empathy, reasoned persuasion, and the rule of law to fundamentally resolve neighborhood conflicts. Correct answer.
  2. Community officers should completely ignore statutory law and only rely on informal customs.
  3. Neighborhood disputes should all be directed to criminal court trials without any attempt at mediation.
  4. Police officers should avoid getting involved in any family or neighbor disputes.

Explanation

The text explicitly states that community officers must integrate 'emotion, reason, and law' (情、理、法) to resolve grievances at their root, achieving '案结事了人和' (case closed, matter settled, harmony restored).

Question 7Meaning, paragraph organization and warranted inference

Read the following paragraph: 国家建立全国统一的DNA数据库与指纹自动识别系统（AFIS），使得积压多年的陈年命案具备了破案的技术支撑。通过对历史现场物证的二次检验与高通量比对，一系列年代久远、线索中断的重大疑难案件相继告破。这充分表明，前沿刑事科学技术是提升公安机关新质战斗力的关键引擎。 Which title is most appropriate for this paragraph?

  1. 刑事科学技术：赋能命案积案攻坚的锋利刃剑 Correct answer.
  2. 传统侦查手段在现代警务中的彻底淘汰
  3. 全国指纹数据库建设的历史局限性
  4. 微量物证提取标准的国际争议

Explanation

The passage highlights how modern forensic technology (DNA databases, AFIS) provides technical empowerment to solve cold cases and serve as an engine of police combat capability. The title '刑事科学技术：赋能命案积案攻坚的锋利刃剑' encapsulates this core theme precisely.

Question 8Meaning, paragraph organization and warranted inference

What is the implied intent of the following internal supervisory circular (警务督察通报)? 通报指出：个别基层单位在接处警过程中，仍存在‘推诿管辖、出警迟缓、记录不全’等现象。各级公安机关必须紧盯有警不接、有案不立、压案不查等执法突出问题，严格落实首接责任制，以铁的纪律倒逼规范执法习惯的养成。 What is the supervisory organ's main objective?

  1. To enforce strict accountability and mandatory first-responder responsibility to eradicate procedural policing laxity. Correct answer.
  2. To reduce the total number of 110 calls by refusing to log non-emergency inquiries.
  3. To abolish local police jurisdiction boundaries across all provincial borders.
  4. To encourage officers to delegate emergency dispatch duties to private contractors.

Explanation

The circular aims to rectify outstanding law enforcement shortcomings (tardy response, jurisdictional buck-passing, unrecorded cases) by enforcing the first-responder responsibility system (首接责任制) and ironclad disciplinary oversight.

Question 9Meaning, paragraph organization and warranted inference

Read the excerpt: 人脸识别与视频AI算法在城市治安防控中发挥了巨大作用，但如果过分迷信算法的‘绝对准确’，忽视侦查员的人工复核与实地摸排，就容易导致‘信息误判’。算法模型输出的比对相似度只是概率参考，绝不能直接等同于法律意义上的定案证据。 Which of the following assumptions is challenged by the author?

  1. Algorithmic facial similarity scores can directly substitute for thorough human evidentiary verification. Correct answer.
  2. Artificial intelligence has zero utility in modern public security surveillance.
  3. On-scene physical ground verification is entirely useless in modern policing.
  4. Video cameras should be removed from all public spaces.

Explanation

The author directly refutes the dangerous assumption that algorithmic probability matches ('比对相似度') can be treated as infallible legal evidence without manual human verification ('绝不能直接等同于法律意义上的定案证据').

Question 10Meaning, paragraph organization and warranted inference

According to the following report on cross-border telecom fraud crackdowns, which statement is factually accurate? 在公安部统一部署下，多地公安机关依托国际执法合作机制，会同东南亚多国警方开展跨国联合打击行动。截至2025年底，共捣毁境外诈骗窝点120余处，押解回国涉案人员3.5万余名，拦截涉诈资金28.4亿元，实现了对境外犯罪集团‘金主’、骨干及黑产链条的全链条重创。 Based on the text, which statement is true?

  1. The joint operations successfully dismantled more than 120 overseas fraud hideouts and repatriated over 35,000 suspects. Correct answer.
  2. All repatriated suspects were released immediately upon arrival at border ports without investigation.
  3. The operations were conducted exclusively by municipal police without international law enforcement cooperation.
  4. Zero illicit funds were intercepted during the campaign.

Explanation

The text explicitly states: '共捣毁境外诈骗窝点120余处，押解回国涉案人员3.5万余名', directly corroborating that the joint operations dismantled over 120 fraud hideouts and repatriated more than 35,000 suspects.

Question 11Meaning, paragraph organization and warranted inference

Read the passage on border narcotics interdiction: 边境缉毒工作具有高度的危险性与复杂性。贩毒分子往往采取人体藏毒、特制暗格改装车辆、利用无人机跨境投送等隐蔽手段。边境移民管理警察与缉毒民警必须构筑‘空中看、陆上堵、水上查、网上控’的立体化立体防控网，才能筑牢西南边陲的禁毒钢铁长城。 What is the primary requirement for effective border narcotics control highlighted in this passage?

  1. Establishing a multi-dimensional integrated defense network across aerial, land, maritime, and cyber domains. Correct answer.
  2. Relying entirely on stationary road toll gates without technological assistance.
  3. Permitting drug traffickers free passage across unpopulated mountain ranges.
  4. Transferring all border interdiction duties to commercial delivery firms.

Explanation

The passage explicitly concludes that officers must establish a '立体化立体防控网' ('空中看、陆上堵、水上查、网上控' - multi-dimensional integrated control net) to counter complex and covert smuggling methods.

Question 12Meaning, paragraph organization and warranted inference

Which of the following slogans in a community fire safety awareness campaign best conveys a warm, persuasive, and safety-conscious tone for residents?

  1. 用火用电莫大意，安全常识记心间；楼道畅通清杂物，万家安宁福相伴。 Correct answer.
  2. 谁敢在楼道堆杂物就立刻拘留谁，后果自负！
  3. 发生火灾都是居民自己不小心，公安部门概不承担救援义务！
  4. 想要不死于火灾，就必须购买本辖区指定品牌的昂贵灭火器！

Explanation

The slogan reminding residents to keep hallways clear of clutter and observe electrical and fire safety is rhythmic, polite, clear, and encouraging, embodying the civilized mass-outreach communication standard for public security and fire safety education.

Question 13Meaning, paragraph organization and warranted inference

Fill in the blanks with the most precise combination: 在开展常态化扫黑除恶斗争中，必须坚持深挖彻查，把打击黑恶势力犯罪与反腐败、基层‘拍蝇’结合起来，坚决______黑恶势力‘保护伞’，从根本上______黑恶势力滋生土壤。

  1. 打掉；铲除 Correct answer.
  2. 保护；培养
  3. 掩盖；松动
  4. 放任；播撒

Explanation

In standard anti-organized crime doctrine, '打掉...保护伞' (topple protective umbrella corruption) and '铲除...滋生土壤' (eradicate the breeding soil of organized crime) are the precise, authoritative standard collocations.

Question 14Meaning, paragraph organization and warranted inference

Which of the following sentences in a police interrogation/inquiry record (询问笔录) is grammatically clear and free of semantic ambiguity?

  1. 民警依法对目击证人李某进行询问，李某清晰陈述了案发时嫌疑人的体貌特征与逃跑方向。 Correct answer.
  2. 李某看见张某和王某打架，他拿起旁边的木棍打了他一下。（代词指代不明）
  3. 办案民警把涉案车辆开回派出所后，他的手机突然响了。（所有权指代不清）
  4. 嫌疑人指认现场时，许多围观群众的亲属都在场拍照。（定语修饰歧义）

Explanation

The inquiry record describing the lawful interrogation of witness Li, who clearly described the suspect's physical appearance and escape direction, has unambiguous subjects, clear actions, and precise legal phrasing. The other sentences suffer from severe syntactic ambiguity (unclear pronoun references '他', '他的', and ambiguous modifier scopes).

Question 15Meaning, paragraph organization and warranted inference

Read the paragraph: 现代警务机制改革的着力点在于构建‘专业+机制+大数据’的新型警务运行模式。通过打通警种壁垒，重塑业务流程，形成‘情指行’一体化实战化运行机制，使警务指挥更加扁平、响应更加迅捷、打击更加精准。 What is the core structural objective of the modern policing mechanism reform described?

  1. Building a 'Professionalism + Mechanism + Big Data' operational model with integrated, flat, and rapid 'Intelligence-Command-Action' workflows. Correct answer.
  2. Increasing bureaucratic layers and administrative reporting hierarchies.
  3. Separating intelligence analysts completely from frontline patrol commanders.
  4. Abolishing all specialized investigative divisions.

Explanation

The text highlights the core reform goal: creating the '专业+机制+大数据' (Professionalism + Mechanism + Big Data) framework to power the '情指行' (Intelligence-Command-Action) integrated operational mechanism with flat and agile command.

Question 16Meaning, paragraph organization and warranted inference

Read the risk assessment note: 大型群众性活动的安保工作必须遵循‘安全第一、预防为主、综合治理’的方针。在核定活动承载能力时，不仅要计算场地物理面积与人流疏散通道宽度，还要充分考虑极端天气、突发断电等外部偶发风险，留足安全冗余度。 What inference can be logically drawn from this note?

  1. Venue capacity calculation must incorporate worst-case risk factors rather than relying strictly on nominal square footage. Correct answer.
  2. Large events should never be permitted under any circumstances.
  3. Security personnel only need to check ticket authenticity at entry gates.
  4. Weather forecasts have no influence on crowd safety management.

Explanation

The passage explicitly demands that capacity calculations look beyond nominal physical area ('不仅要计算场地物理面积') to account for external risks (extreme weather, power failure) and reserve safety margins (留足安全冗余度).

Question 17Meaning, paragraph organization and warranted inference

Read the interrogator's behavioral observation: 在审讯过程中，当民警提及案发当晚西郊仓库的特定隐蔽细节时，嫌疑人王某出现了瞳孔骤缩、呼吸短促、无意识反复摩擦双膝的生理与肢体反应，且在回答问题时刻意回避视线接触，答非所问。 What is the most reasonable investigative deduction from this observation?

  1. The behavior may reflect stress, discomfort, fear, fatigue, or many other causes; investigators should avoid inferring crime-scene knowledge from body language alone and seek lawful corroborating evidence. Correct answer.
  2. The suspect was completely relaxed and had no knowledge of any criminal activity.
  3. The interrogating officer should immediately terminate all inquiries and release the suspect unconditionally.
  4. The physiological signs prove conclusively beyond all doubt that the suspect committed murder, requiring no further physical evidence.

Explanation

Gaze, breathing, pupil, and self-touch behavior are nonspecific and culturally and individually variable. They may guide a neutral follow-up question but cannot establish familiarity, deception, or guilt. Investigators should document statements and obtain independently verifiable evidence while respecting interrogation rules.

Question 18Meaning, paragraph organization and warranted inference

Choose the most appropriate news headline for a joint nationwide campaign against counterfeit pharmaceuticals: 为切实保障人民群众生命健康权益，公安部近日会同国家药监局部署开展‘昆仑’专项打击行动，全链条摧毁假冒伪劣药品生产、包装、网络分销黑产窝点800余处，涉案总金额逾15亿元。

  1. 公安部会同药监部门开展专项行动 全链条重拳斩断假药犯罪黑手 Correct answer.
  2. 假药生产工艺在多地得到快速推广传播
  3. 药品监督管理部门宣布暂停所有实体药店日常营业
  4. 全国范围内突发重大假药危机且无法控制

Explanation

The headline '公安部会同药监部门开展专项行动 全链条重拳斩断假药犯罪黑手' provides an authoritative, positive, and accurate summary capturing the joint enforcement agency action and full-chain crackdown on counterfeit drugs.

Question 19Meaning, paragraph organization and warranted inference

Choose the most appropriate transitional conjunctions to fill in the blanks: 打击治理跨境赌博犯罪是一项复杂的系统工程，______需要境内各警种密切协作，______需要深化国际执法合作；______切断资金链与技术链，______能从根本上遏制跨境赌博蔓延势头。

  1. 不仅……也；唯有……才 Correct answer.
  2. 虽然……但；即使……也
  3. 因为……所以；如果……就
  4. 既然……就；哪怕……也

Explanation

The first clause establishes a progressive coordinate requirement ('不仅...也' - not only domestically but also internationally). The second clause establishes an exclusive conditional relationship ('唯有...才' - only by cutting funding/tech chains can we fundamentally curb the crimes).

Question 20Meaning, paragraph organization and warranted inference

Analyze the following passage regarding legal amendments: 对道路交通安全违法行为的扣分与罚款，本质上是行政管理手段而非财政创收工具。处罚的严厉程度必须与违法行为的社会危害性相适应。过高的非必要惩罚不仅无法提高守法自觉性，反而可能激化执法对立；只有通过科学合理的分级惩戒与教育引导相结合，才能实现道路畅通与群众理解的双赢。 What is the core argument of this passage?

  1. Traffic enforcement penalties must adhere to the principle of proportionality and educational deterrence rather than excessive punitive fines. Correct answer.
  2. Traffic police should cancel all penalty point scoring and let drivers self-regulate.
  3. Increasing fines tenfold is the most effective traffic management solution.
  4. Traffic administration's primary goal is maximizing municipal fiscal revenue.

Explanation

The text argues that traffic penalties must correspond strictly to social harm (proportionality principle) and combine punishment with educational guidance rather than revenue-focused excessive sanctions.

Question 21Meaning, paragraph organization and warranted inference

Read the emergency drill evaluation excerpt: 演练评估显示，在接到模拟突发暴恐警情后，特警突击组在5分钟内完成武装集结并到达指定封控点，但现场疏散组在引导周边群众撤离时，由于扩音指令不够清晰、避难路线指引牌缺失，导致局部通道发生短时人流拥堵。 What was the identified operational bottleneck during the drill?

  1. Flaws in crowd evacuation guidance due to unclear acoustic commands and missing signage. Correct answer.
  2. SWAT assault team failed to assemble within the required time.
  3. The entire emergency drill was cancelled due to heavy rain.
  4. Commanders refused to issue tactical weapons to the assault team.

Explanation

The text explicitly states that while SWAT arrived within 5 minutes, the crowd evacuation group encountered bottlenecks due to unclear megaphone commands ('扩音指令不够清晰') and missing evacuation signs ('避难路线指引牌缺失').

Question 22Meaning, paragraph organization and warranted inference

What is the primary rhetorical purpose of a police officer delivering a community anti-burglary speech with the opening: '大家平时出门倒垃圾，哪怕只有两分钟，也千万别图省事不反锁防盗门！许多入室盗窃正是利用这短暂的‘两分钟’溜门得手的……'?

  1. To engage residents with a relatable everyday scenario and heighten vigilance against opportunistic burglary. Correct answer.
  2. To criticize all community residents for being lazy.
  3. To advertise a specific brand of smart mechanical door locks.
  4. To announce that burglary has been completely eradicated across the city.

Explanation

The officer uses a concrete, relatable daily scenario (taking out trash for 2 minutes) to capture attention, shatter complacency, and educate residents on anti-burglary locking habits.

Question 23Meaning, paragraph organization and warranted inference

Compare the statements of Witness A and Witness B regarding a hit-and-run collision: Witness A: 'I saw a dark sedan speed away heading north immediately after hitting the cyclist at around 21:15.' Witness B: 'At approximately 21:15, I heard a loud crash. A dark blue SUV with a damaged front bumper turned right onto North Avenue.' What is the verified common factual consensus between both witnesses?

  1. A dark-colored motor vehicle fled heading north right around 21:15 after the collision. Correct answer.
  2. The vehicle was definitely a red convertible sports car.
  3. The driver was an elderly woman wearing yellow glasses.
  4. The incident occurred at 06:00 in the morning.

Explanation

Both witnesses corroborate three core facts: the time (~21:15), the color family of the vehicle (dark/dark blue), and the flight direction (north/North Avenue).

Question 24Meaning, paragraph organization and warranted inference

Identify the logical flaw in the following internal audit report conclusion: 'In District X, police response times to 110 calls averaged 8.5 minutes, whereas in District Y they averaged 4.2 minutes. Therefore, District X patrol officers are half as diligent and dedicated as District Y officers.' What critical variable is ignored by this conclusion?

  1. It ignores objective geographic, traffic congestion, territorial surface area, and call density differences between the two districts. Correct answer.
  2. It ignores the fact that 110 calls should never be answered by police officers.
  3. It assumes that faster response times are always illegal.
  4. It assumes that patrol officers in District Y do not possess motor vehicles.

Explanation

Comparing average response times directly without controlling for geographic area, road network density, peak-hour traffic bottlenecks, or per-capita patrol unit allocation is a false attribution fallacy (attributing external structural differences solely to personal work diligence).

Question 25Deduction, argument evaluation and explicit conditions

In a graphic series question (图形推理), the given sequence of five geometric figures shows clockwise rotation of an internal arrow by 45° in each successive step, while the count of black dots increases by 1 each step (1 dot, 2 dots, 3 dots, 4 dots, 5 dots). What must the 6th figure in the sequence possess?

  1. An arrow rotated 225° from the starting orientation and exactly 6 black dots. Correct answer.
  2. An arrow pointing in the initial starting orientation and 4 black dots.
  3. A counter-clockwise 90° arrow and 5 black dots.
  4. A static arrow and 7 black dots.

Explanation

Progression 1: 0° rotation, 1 dot. Progression 2: 45°, 2 dots. Progression 3: 90°, 3 dots. Progression 4: 135°, 4 dots. Progression 5: 180°, 5 dots. Progression 6: 180° + 45° = 225° clockwise rotation, and 5 + 1 = 6 black dots. The figure with an arrow rotated 225° and 6 black dots satisfies both rules.

Question 26Deduction, argument evaluation and explicit conditions

In graphic reasoning involving connected graph topology (一笔画规律 / 奇点数), a figure can be drawn in a single continuous stroke without lifting the pen or retracing lines if and only if the number of odd vertices (奇点 - points connected to an odd number of lines) is:

  1. Exactly 0 or 2. Correct answer.
  2. Any odd number (1, 3, 5, etc.).
  3. Exactly 4.
  4. Greater than 6.

Explanation

Under Euler's theorem on Eulerian paths, a connected planar graph is unicursal (can be drawn in 1 continuous stroke / 一笔画) if and only if the number of vertices with odd degrees (奇点) is exactly 0 (Eulerian circuit) or 2 (Eulerian trail starting at one odd vertex and ending at the other).

Question 27Deduction, argument evaluation and explicit conditions

A valid cube net has four faces in a straight row in the order A–B–C–D, with face E directly above B and face F directly below B. When folded, which pair must be opposite and therefore can never share an edge?

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

Explanation

Using B as the front face, A folds to the left and C to the right, so A and C are opposite. D folds to the back opposite B, while E and F become the top and bottom. The explicit net-not a vague rule detached from a diagram-determines the relationship.

Question 28Deduction, argument evaluation and explicit conditions

In a 4x4 black-and-white grid movement puzzle, a black square in Row 1 Column 1 moves 1 cell right each step (wrapping around to Column 1 when exceeding Column 4), while a black square in Row 4 Column 4 moves 1 cell up each step. At Step 3 (starting from Step 0), what are the coordinates of the two black squares?

  1. Square 1 at (Row 1, Column 4) and Square 2 at (Row 1, Column 4) - overlapping in the top-right corner. Correct answer.
  2. Square 1 at (Row 1, Column 2) and Square 2 at (Row 3, Column 4).
  3. Square 1 at (Row 2, Column 3) and Square 2 at (Row 2, Column 2).
  4. Square 1 at (Row 4, Column 1) and Square 2 at (Row 1, Column 1).

Explanation

Trace each square: Square 1 starts at (R1, C1). Step 1 -> (R1, C2); Step 2 -> (R1, C3); Step 3 -> (R1, C4). Square 2 starts at (R4, C4). Step 1 -> (R3, C4); Step 2 -> (R2, C4); Step 3 -> (R1, C4). At Step 3, both black squares occupy (Row 1, Column 4), overlapping in the upper-right corner.

Question 29Deduction, argument evaluation and explicit conditions

In a graphic series based on enclosed space counts (封闭空间数 / 面数量), the sequence of figures displays enclosed region counts of: 2, 3, 4, 5, 6. Which candidate figure should logically follow to complete the pattern?

  1. A geometric figure containing exactly 7 enclosed regions (面的数量为7). Correct answer.
  2. An open straight line with 0 enclosed regions.
  3. A simple circle with 1 enclosed region.
  4. A figure with 12 open line segments and 3 enclosed regions.

Explanation

The series follows an arithmetic progression of enclosed region counts (封闭面数量): 2, 3, 4, 5, 6, n. The next number in the sequence must be n = 7 enclosed regions.

Question 30Deduction, argument evaluation and explicit conditions

Definition Matching: 'Chain of Custody' (证据保管链) refers to the unbroken chronological documentation and physical control tracking the collection, custody, transfer, analysis, and court presentation of physical or electronic evidence. Which scenario represents a serious breach of the Chain of Custody?

  1. An investigator places bloodstained clothing extracted from a murder scene into their personal gym locker overnight without sealing, logging, or signing a transfer custody form. Correct answer.
  2. Forensic technicians seal blood samples in barcoded tamper-evident bags and sign mutual custody receipts upon laboratory delivery.
  3. Digital detectives extract a hard drive using write-blockers, compute its SHA-256 hash value, and log it in the case registry.
  4. A court evidence clerk logs in a seized firearm with two matching police officer signatures and places it in a biometric safe.

Explanation

Placing unsealed murder evidence in a personal gym locker with no logs or transfer forms breaks the chain of custody completely, creating opportunities for contamination, loss, or tampering, rendering the evidence vulnerable to exclusion.

Question 31Deduction, argument evaluation and explicit conditions

Analogy Reasoning (类比推理): 警服 : 警察 : 执法 (Police Uniform : Police Officer : Law Enforcement) Which of the following triads shares the exact same relationship (Specific Professional Vestment : Professional Agent : Core Professional Function)?

  1. 法袍 : 法官 : 审判 (Judicial Robe : Judge : Adjudication) Correct answer.
  2. 钢笔 : 作家 : 稿费 (Pen : Writer : Royalties)
  3. 黑板 : 教师 : 学校 (Blackboard : Teacher : School)
  4. 听诊器 : 医生 : 医院 (Stethoscope : Doctor : Hospital)

Explanation

The relationship in the prompt is: [Professional attire/vestment required for duty] : [Professional practitioner] : [Core statutory professional function]. A '法袍' (Judicial Robe) is worn by a '法官' (Judge) whose core statutory function is '审判' (Adjudication).

Question 32Deduction, argument evaluation and explicit conditions

Logic Deduction (逻辑推理): Detectives interrogate four burglary suspects (Jia, Yi, Bing, and Ding). Exactly ONE of them committed the burglary, and exactly ONE of them is telling the TRUTH, while the other three are lying. - Jia says: 'Bing committed the burglary.' - Yi says: 'I did not commit the burglary.' - Bing says: 'Ding committed the burglary.' - Ding says: 'Bing is lying.' Who is telling the truth, and who is the actual burglar?

  1. Ding is telling the truth, and Yi is the actual burglar. Correct answer.
  2. Jia is telling the truth, and Bing is the actual burglar.
  3. Yi is telling the truth, and Jia is the actual burglar.
  4. Bing is telling the truth, and Ding is the actual burglar.

Explanation

Analyze the contradiction: Bing says 'Ding did it' and Ding says 'Bing is lying'. These two statements are contradictory; therefore, exactly ONE of Bing or Ding is telling the truth, and the other is lying. Since only ONE person in total tells the truth, Jia and Yi MUST BOTH BE LYING. Since Yi is lying when saying 'I did not commit the burglary', Yi IS the actual burglar! Since Yi is the burglar, Ding did not do it, so Bing's statement ('Ding did it') is false, and Ding's statement ('Bing is lying') is TRUE. Thus, Ding is telling the truth, and Yi is the burglar.

Question 33Deduction, argument evaluation and explicit conditions

Logic Deduction: It is known that: 'Only if an individual was physically present inside the laboratory between 22:00 and 23:00 (P), could they have stolen the classified encryption key (Q).' (只有在22:00至23:00进入过实验室，才可能盗取涉密密钥)。 If it is conclusively proven that Suspect Zhang was at a restaurant across the city during that entire hour (Not P), what conclusion follows with absolute logical certainty?

  1. Suspect Zhang could not have stolen the classified encryption key (张某不可能盗取涉密密钥). Correct answer.
  2. Suspect Zhang definitely stole the classified encryption key.
  3. The encryption key was definitely not stolen by anyone.
  4. Suspect Zhang must have entered the laboratory the next morning.

Explanation

The statement is a necessary condition: '只有 P，才 Q' (Q -> P). By the contrapositive law (否定后件律 / 否后必否前): If Not P (was not in the lab), then Not Q (could not have stolen the key). Therefore, Zhang could not have stolen the key.

Question 34Deduction, argument evaluation and explicit conditions

Evidentiary Reasoning (加强论证): The prosecution argues that Suspect Chen broke into a jewelry boutique at 02:00 on April 12. Which of the following newly discovered pieces of evidence provides the STRONGEST support / corroboration for the prosecution's argument?

  1. At 02:03 on April 12, Chen's smartphone connected to the private Wi-Fi router inside the boutique, and his fresh thumbprint was extracted from the smashed display glass. Correct answer.
  2. Chen told his roommate three months ago that he dislikes jewelry.
  3. A boutique located 50 kilometers away was burgled by an unknown person two years ago.
  4. Chen was observed walking his dog near his own residence at 14:00 on April 12.

Explanation

Direct physical and digital forensic placement at the exact scene and timestamp (Wi-Fi router connection at 02:03 + fresh thumbprint on the broken showcase glass) provides direct, undeniable corroboration of presence and physical tampering.

Question 35Deduction, argument evaluation and explicit conditions

Evidentiary Reasoning (削弱论证): The initial police theory posits that a warehouse fire at 23:00 was caused by a cigarette discarded by Security Guard Wu during his 22:55 patrol. Which of the following findings most seriously WEAKENS or refutes this theory?

  1. Forensic electrical inspection confirmed that a major short circuit with intense arc melting occurred inside an energized distribution box in the warehouse ceiling at 22:40, sparking an internal wall insulation fire before Wu arrived. Correct answer.
  2. Security Guard Wu admits he has been smoking for 10 years.
  3. The warehouse was insured against fire by the owner.
  4. A no-smoking sign was posted on the exterior gate of the warehouse.

Explanation

Providing definitive physical proof of an independent prior cause (arcing short circuit in the electrical distribution box at 22:40 before Wu's arrival) establishes an alternative cause (另有他因), completely refuting the discarded cigarette hypothesis.

Question 36Deduction, argument evaluation and explicit conditions

Categorical Syllogism (三段论推理): Given the following two premises: 1. All qualified police academy graduates who pass the joint recruitment exam are appointed as people's police officers (所有通过公安联考的公安院校毕业生都被录用为人民警察). 2. Some members of the volunteer emergency rescue team are qualified police academy graduates who passed the joint recruitment exam (部分青年应急救援队成员是通过公安联考的公安院校毕业生). What conclusion MUST logically follow?

  1. Some members of the volunteer emergency rescue team are appointed as people's police officers (部分青年应急救援队成员被录用为人民警察). Correct answer.
  2. All people's police officers are members of the volunteer emergency rescue team.
  3. All members of the volunteer emergency rescue team are people's police officers.
  4. No members of the volunteer emergency rescue team are people's police officers.

Explanation

Let R = Rescue team members, G = Graduates who passed exam, P = People's police. Premise 1: All G are P (G ⊆ P). Premise 2: Some R are G (R ∩ G ≠ ∅). Since those elements in R that are in G must also be in P, it follows with certainty that Some R are P (部分青年应急救援队成员被录用为人民警察).

Question 37Deduction, argument evaluation and explicit conditions

Arrangement Puzzle (排列组合推理): Five police officers (A, B, C, D, and E) are scheduled for duty on Monday through Friday, with exactly one officer on duty each day, subject to the following rules: 1. A must be on duty on Wednesday. 2. B must be on duty on an earlier day than C (B before C). 3. D must be on duty on the day immediately following E (E and D are consecutive, E then D). 4. E must be on duty on Thursday. Which day must Officer B be on duty?

  1. Monday Correct answer.
  2. Tuesday
  3. Thursday
  4. Friday

Explanation

Rule 1 fixes A on Wednesday: [_, _, A, _, _]. Rule 4 assigns E to Thursday, which by Rule 3 forces D onto Friday: [_, _, A, E, D]. The remaining available days are Monday and Tuesday, which must be filled by B and C. Rule 2 stipulates that B precedes C, leaving Monday for B and Tuesday for C, yielding the unique valid schedule [B, C, A, E, D]. Therefore, Officer B must be on duty on Monday.

Question 38Deduction, argument evaluation and explicit conditions

Flaw in Reasoning (逻辑谬误辨析): A statistical report noted: 'In City Z, ice cream sales and the number of reported street assault cases both peaked during the months of July and August. Therefore, consuming ice cream causes aggressive and violent criminal behavior.' What fundamental logical fallacy does this argument commit?

  1. Confusing correlation with causation / Ignoring a common confounding variable (混淆相关性与因果性，忽视了高温夏季这一共同诱因). Correct answer.
  2. Circular reasoning (循环论证).
  3. Ad hominem attack (人身攻击).
  4. False dilemma (虚假二分法).

Explanation

This is a classic 'Cum hoc ergo propter hoc' (correlation does not imply causation) fallacy. Both ice cream sales and street altercations increase in summer due to a shared lurking variable: hot summer temperatures and increased outdoor night activity (共同第三变量 / 混淆相关与因果).

Question 39Quantitative relations, rates and accountable data interpretation

A public security precinct divides its commercial district into a circular patrol route with a total perimeter of 3,600 meters. Patrol Team A walks at a constant speed of 60 meters/minute, and Patrol Team B walks in the opposite direction at 90 meters/minute. If they depart simultaneously from the same community police booth, how many minutes will elapse before they meet for the first time?

  1. 24 minutes Correct answer.
  2. 30 minutes
  3. 36 minutes
  4. 40 minutes

Explanation

This is a standard circular motion problem in opposite directions. The combined relative closing speed is v_total = 60 + 90 = 150 meters/minute. The time required to complete the 3,600-meter circuit together is t = Distance / v_total = 3600 / 150 = 24 minutes.

Question 40Quantitative relations, rates and accountable data interpretation

A suspect vehicle flees along a straight highway at a constant speed of 90 km/h. A traffic police pursuit cruiser stationed at a toll plaza departs 10 minutes later in pursuit along the same route at a constant speed of 120 km/h. How many kilometers from the toll plaza will the police cruiser successfully intercept the suspect vehicle?

  1. 60 km Correct answer.
  2. 45 km
  3. 75 km
  4. 90 km

Explanation

In 10 minutes (1/6 hour), the suspect vehicle covers a head start distance: d_0 = 90 km/h * (1/6) h = 15 km. The relative catching speed of the police cruiser is: v_rel = 120 - 90 = 30 km/h. Time required for interception: t = 15 / 30 = 0.5 hours (30 minutes). Total distance traveled by the police cruiser from the toll plaza: Distance = 120 km/h * 0.5 h = 60 km.

Question 41Quantitative relations, rates and accountable data interpretation

A municipal police station is assigned to conduct household safety inspections across 600 residential units. Team A working alone can complete the inspections in 10 days, while Team B working alone can complete the inspections in 15 days. If Team A and Team B work together, how many days will it take them to complete all 600 inspections?

  1. 6 days Correct answer.
  2. 7.5 days
  3. 8 days
  4. 12 days

Explanation

This is a classic work-rate problem. Team A's daily rate is 1/10 of the total work; Team B's daily rate is 1/15. Combined daily rate = 1/10 + 1/15 = 3/30 + 2/30 = 5/30 = 1/6. Therefore, working together they require: Total Time = 1 / (1/6) = 6 days (or 60 units/day + 40 units/day = 100 units/day; 600 / 100 = 6 days).

Question 42Quantitative relations, rates and accountable data interpretation

In a telecom fraud investigation, a victim transferred RMB 800,000 to an initial fraud account. The criminals immediately split the funds: 40% was transferred to Account X and the remaining 60% was transferred to Account Y. From Account X, police successfully froze 75% of the funds before withdrawal. From Account Y, police froze 50% of the funds. What is the total amount of money successfully frozen by the police?

  1. RMB 480,000 Correct answer.
  2. RMB 520,000
  3. RMB 400,000
  4. RMB 360,000

Explanation

Calculate step-by-step: Funds in Account X = 800,000 * 40% = RMB 320,000. Frozen from X = 320,000 * 75% = RMB 240,000. Funds in Account Y = 800,000 * 60% = RMB 480,000. Frozen from Y = 480,000 * 50% = RMB 240,000. Total funds frozen = 240,000 + 240,000 = RMB 480,000 (which is 60% of the total RMB 800,000).

Question 43Quantitative relations, rates and accountable data interpretation

A criminal investigation task force consists of 6 detectives. The commander needs to select 3 detectives to be assigned respectively to 3 distinct surveillance observation posts (Post Alpha, Post Beta, and Post Gamma). In how many different ways can these assignments be made?

  1. 120 ways Correct answer.
  2. 20 ways
  3. 60 ways
  4. 216 ways

Explanation

Because the three observation posts are distinct (ordered positions), this is a permutation problem P(6, 3) (or A_6^3): P(6, 3) = 6 * 5 * 4 = 120 ways.

Question 44Quantitative relations, rates and accountable data interpretation

To intercept a fleeing criminal vehicle, police set up two sequential, independent checkpoints (Checkpoint 1 and Checkpoint 2) along a single road. The probability of successfully intercepting the vehicle at Checkpoint 1 is 0.7, and the probability of successfully intercepting the vehicle at Checkpoint 2 (if it passes Checkpoint 1) is 0.8. What is the overall probability that the suspect vehicle is intercepted by at least one of the two checkpoints?

  1. 0.94 Correct answer.
  2. 0.85
  3. 0.56
  4. 0.75

Explanation

Use the complement rule. Probability of evading Checkpoint 1: P(E1) = 1 - 0.7 = 0.3. Probability of evading Checkpoint 2: P(E2) = 1 - 0.8 = 0.2. Since the checkpoints are independent, the probability of evading both checkpoints is: P(E_total) = 0.3 * 0.2 = 0.06. Therefore, the probability of being intercepted at least once is: P(Intercept) = 1 - 0.06 = 0.94.

Question 45Quantitative relations, rates and accountable data interpretation

In a ballistic forensics lab, there are 5 different calibers of bullet casings recovered from a crime warehouse. Under the worst-case Pigeonhole Principle (最不利原则), what is the minimum number of casings an examiner must draw at random without replacement to guarantee that they have at least 4 casings of the exact same caliber?

  1. 16 casings Correct answer.
  2. 15 casings
  3. 20 casings
  4. 12 casings

Explanation

Using the Pigeonhole Principle in the worst-case scenario: the examiner draws the maximum number of casings without satisfying the condition (i.e. exactly 3 casings for each of the 5 calibers). Worst-case non-satisfying draw = 5 calibers * 3 casings = 15 casings. Drawing 1 additional casing guarantees that one of the calibers reaches 4. Minimum required draws = 15 + 1 = 16 casings.

Question 46Quantitative relations, rates and accountable data interpretation

In a hypothetical geometry exercise, a circular restricted zone has radius20meters and is expanded to40meters. By how many square meters does its area increase? Take pi≈3.14. These radii are exercise data, not an explosive-safety cordon recommendation.

  1. 3,768 m² Correct answer.
  2. 1,256 m²
  3. 5,024 m²
  4. 2,512 m²

Explanation

The area increase is pi*(40^2-20^2)=3.14*(1600-400)=3768square meters. This is a supplied geometric model. Actual explosive-safety distances require specialist assessment and cannot be inferred from this exercise.

Question 47Quantitative relations, rates and accountable data interpretation

During a 7-day holiday security campaign, a traffic police division recorded traffic violations that formed an arithmetic progression (等差数列). On Day 1, they recorded 120 violations, and on Day 7, they recorded 240 violations. What was the total number of traffic violations recorded across all 7 days of the campaign?

  1. 1,260 violations Correct answer.
  2. 1,080 violations
  3. 1,440 violations
  4. 960 violations

Explanation

For an arithmetic progression of n terms, the sum S_n = n * (a_1 + a_n) / 2. Here n = 7, a_1 = 120, and a_7 = 240. S_7 = 7 * (120 + 240) / 2 = 7 * 360 / 2 = 7 * 180 = 1,260 violations.

Question 48Quantitative relations, rates and accountable data interpretation

In an illegal pyramid scheme (传销组织) fraud investigation, 500 tier-1 victims each invested RMB 10,000 principal. The scheme operators returned 15% of the total pooled principal as 'guaranteed monthly profit returns' during the first month, and another 10% in the second month. In the third month, the operators absconded with all remaining funds after spending RMB 300,000 on luxury expenses. How much unspent illicit principal remains to be seized by the police?

  1. RMB 3,450,000 Correct answer.
  2. RMB 3,750,000
  3. RMB 3,200,000
  4. RMB 4,000,000

Explanation

Total initial principal collected = 500 * 10,000 = RMB 5,000,000. Month 1 returns paid = 5,000,000 * 15% = RMB 750,000. Month 2 returns paid = 5,000,000 * 10% = RMB 500,000. Total returns distributed = 750,000 + 500,000 = RMB 1,250,000. Remaining balance before expenses = 5,000,000 - 1,250,000 = RMB 3,750,000. Subtract luxury expenses spent = 3,750,000 - 300,000 = RMB 3,450,000 remaining to be seized.

Question 49Quantitative relations, rates and accountable data interpretation

[Based on Dataset A: City Public Security Bureau Crime Statistics] In 2024, the Bureau recorded 12,000 total criminal cases and cleared (破案) 7,200 cases. In 2025, total recorded criminal cases dropped to 10,000, while cleared cases reached 7,500. What was the percentage-point increase in the overall Case Clearance Rate (破案率) in 2025 compared to 2024?

  1. 15.0 percentage points Correct answer.
  2. 10.0 percentage points
  3. 12.5 percentage points
  4. 8.0 percentage points

Explanation

In 2024, Clearance Rate = 7,200 / 12,000 = 60.0%. In 2025, Clearance Rate = 7,500 / 10,000 = 75.0%. The increase in clearance rate = 75.0% - 60.0% = 15.0 percentage points.

Question 50Quantitative relations, rates and accountable data interpretation

[Based on Dataset A] In 2025, the Bureau's anti-fraud task force recovered RMB 92 million in intercepted telecom fraud funds, representing a year-on-year (YoY) increase of 15% compared to 2024. What was the total amount of intercepted fraud funds recovered in the base period of 2024 (基期量计算)?

  1. RMB 80.0 million Correct answer.
  2. RMB 78.2 million
  3. RMB 85.0 million
  4. RMB 72.5 million

Explanation

Base Period Value = Current Value / (1 + Growth Rate) = 92 / (1 + 0.15) = 92 / 1.15 = RMB 80.0 million.
