Meaning: 'Rewards' means something given in recognition of service, effort, or achievement, in this case, for providing information.

Wrong options:

• compensation: While 'compensation' refers to something given to make up for loss or injury, it does not specifically imply a positive incentive like 'rewards' does.
• bribes: 'Bribes' implies illegal or unethical payments to influence actions, which does not fit the lawful context of police offers.
• monetary: 'Monetary' is an adjective describing something related to money, but it does not serve as a noun to indicate what is being offered.

Correct answer: leading

Explanation: The word 'leading' is appropriate as it indicates guiding or directing towards the arrests, fitting the context of the sentence. It is a gerund that aligns with the action of providing information that results in arrests.

Meaning: 'Leading' means guiding or directing, in this case, referring to information that helps in the process of making arrests.

Wrong options:

• conducting: 'Conducting' implies managing or directing an activity, which does not specifically relate to providing information for arrests.
• ruling: 'Ruling' refers to making a decision or judgment, which does not fit the context of providing information for arrests.
• fronting: 'Fronting' suggests presenting or leading a group, which does not align with the context of information leading to arrests.

Correct answer: detained

Explanation: The term 'detained' is correct as it refers to being held in custody, which fits the context of the sentence regarding a legal situation. It is the past participle form that matches the tense required here.

Meaning: 'Detained' means being held in custody or confinement, particularly by law enforcement, as in this case.

Wrong options:

• caught: 'Caught' implies being captured or discovered, but it does not convey the legal context of being held by authorities as 'detained' does.
• constrained: 'Constrained' suggests being restricted or limited, which does not accurately describe the legal action of being held by police.
• implemented: 'Implemented' refers to putting something into effect, which does not fit the context of being held in custody.

Correct answer: violating

Explanation: The word 'violating' is suitable as it indicates breaking or disregarding a law, which aligns with the context of the activists' actions. It is a gerund that fits grammatically and contextually in the sentence.

Meaning: 'Violating' means breaking or failing to comply with a law or rule, in this case, the National Security Law.

Wrong options:

• defying: 'Defying' implies openly resisting or challenging, which does not specifically convey the legal breach that 'violating' does.
• fouling: 'Fouling' generally refers to making something dirty or unclean, which is not relevant in a legal context.
• passing: 'Passing' suggests moving past something, which does not relate to the act of breaking a law.

Correct answer: individuals

Explanation: The term 'individuals' is appropriate as it refers to distinct persons, fitting the context of the activists being named. It is a plural noun that aligns with the description of the five people involved.

Meaning: 'Individuals' means separate persons or entities, in this case, referring to the activists mentioned.

Wrong options:

• bodies: 'Bodies' typically refers to physical forms or organizations, which does not accurately describe the activists as people.
• residents: 'Residents' implies people living in a specific place, which does not capture the context of their actions as activists.
• examples: 'Examples' refers to instances or cases, which does not fit the context of naming specific people.
