Meaning: 'Introduce' means to bring something into use or operation for the first time, in this case, a new law.

Wrong options:

• adapt: 'Adapt' means to adjust or modify something, which does not fit here as the context is about creating a new law rather than changing an existing one.
• lift: 'Lift' implies removing a restriction or ban, which contradicts the intention of creating a law to ban smoking and vaping.
• enroll: 'Enroll' refers to signing up or registering, which is unrelated to the context of enacting a law.

Correct answer: prohibited

Explanation: The word 'prohibited' is appropriate as it indicates that the sale of vaping products is officially banned in several states. It fits grammatically and contextually, as it describes the action taken by the states regarding vaping products.

Meaning: 'Prohibited' means that something is not allowed or is banned, indicating that the sale of vaping products is illegal in those states.

Wrong options:

• proposed: 'Proposed' means suggested but not yet enacted, which does not fit since the sentence states that the sale is already banned.
• proliferated: 'Proliferated' means to increase rapidly, which is the opposite of what is intended in the context of banning sales.
• promoted: 'Promoted' means to support or encourage, which contradicts the idea of banning the sale of vaping products.

Correct answer: inhaled

Explanation: The word 'inhaled' correctly describes the action of breathing in vapor produced by e-liquids. It fits grammatically and contextually, as it directly relates to how users interact with the vapor from vapes.

Meaning: 'Inhaled' means to breathe in, particularly referring to the act of taking in vapor from a vape or e-cigarette.

Wrong options:

• comprised: 'Comprised' means to consist of or be made up of, which does not fit the context of the action being described.
• compressed: 'Compressed' means to be pressed together, which is not relevant to the action of using a vape.
• exhaled: 'Exhaled' means to breathe out, which is the opposite of what users do when they take in vapor.

Correct answer: touted

Explanation: The word 'touted' is suitable as it indicates that advocates are promoting vapes as a beneficial tool for quitting smoking. It fits grammatically and contextually, as it describes the positive claims made about vapes.

Meaning: 'Touted' means to promote or praise something, especially in a public context, indicating that advocates are speaking favorably about vapes.

Wrong options:

• despised: 'Despised' means to be hated or regarded with contempt, which is contrary to the positive promotion intended in the context.
• criticized: 'Criticized' means to express disapproval, which does not align with the advocates' intention to promote vapes as helpful.
• destroyed: 'Destroyed' means to completely ruin or eliminate, which is irrelevant to the context of promoting vapes.
