To restrain, hinder, arrest, or check (an action, impulse, etc.) is to ____ it.

• A. Inherent
• B. Inhibit
• C. Initial
• D. Initiate

Answer: (B)

The idea being tested is finding a verb that means to hold back or prevent an action or impulse. Inhibit fits perfectly because it specifically means to restrain, hinder, or check something from happening or progressing. For example, fear can inhibit speech, or a suppressant can inhibit a chemical reaction.

Inherent is an adjective describing something that is a natural part of something, not an action of stopping. Initial describes something first or primary in sequence, also an adjective. Initiate means to begin or start something, which is the opposite of holding back.
