Meaning: 'Declined' means to refuse or reject something, in this case, the request to put a hold on the law.

Wrong options:

• fell off: This phrase implies a physical action of falling, which does not fit the context of a legal decision.
• wanted: This suggests a desire rather than a refusal, which contradicts the meaning of the sentence.
• descended: This term refers to moving downwards and does not relate to the context of a legal decision.

Correct answer: bans

Explanation: The word 'bans' is the correct choice as it indicates a prohibition, which is the main action of the law being discussed. It fits grammatically and contextually, as the sentence describes what the law does.

Meaning: 'Bans' means to officially or legally prohibit something, in this case, the sale of certain weapons.

Wrong options:

• quashes: This means to suppress or put an end to something, but it does not specifically indicate a prohibition on sales.
• censured: This refers to expressing disapproval, which does not fit the context of a law regarding sales.
• blockage: This term refers to an obstruction and does not convey the legal prohibition implied by 'bans.'

Correct answer: existing

Explanation: The word 'existing' is appropriate here as it refers to current owners of the restricted items, fitting grammatically and contextually with the requirement to register them.

Meaning: 'Existing' means currently in place or present, referring to those who already own the items.

Wrong options:

• functional: This implies that something is working or operational, which does not specifically relate to ownership.
• subsisting: This term suggests something that is continuing to exist, but it is less commonly used in this context compared to 'existing.'
• ongoing: This refers to something that is currently happening, which does not accurately describe ownership.

Correct answer: law

Explanation: The word 'law' is the most fitting choice as it refers to the legal statute being discussed. It fits grammatically and contextually, as the sentence is about the legal framework regarding gun sales.

Meaning: 'Law' refers to a system of rules that are created and enforced through social or governmental institutions.

Wrong options:

• act: While 'act' can refer to a law, it is less specific and does not match the formal tone of the sentence as well as 'law.'
• scheme: This implies a plan or arrangement, which does not accurately convey the legal context of the sentence.
• decree: This refers to an official order, which is not the same as a law and does not fit the context.

Correct answer: consistently

Explanation: The word 'consistently' fits grammatically as it is an adverb describing how the case has been rebuffed. It aligns with the context of ongoing legal challenges.

Meaning: 'Consistently' means in a way that does not change; regularly or continually, indicating that the lower courts have repeatedly rejected the case.

Wrong options:

• consisted: This is a verb form that does not fit the context of describing how the case has been treated.
• consistant: This is a misspelling of 'consistent' and does not fit grammatically or contextually.
• constraint: This refers to a limitation or restriction, which does not relate to the action of rebuffing a case.
