Which word means undesired?

• A. Adverse
• B. Ambivalent
• C. Apply
• D. Audible

Answer: (A)

The idea being tested is recognizing a word that means undesired or unfavorable. Adverse fits because it describes things that are harmful, unfavorable, or not desired, such as adverse effects from a medication or adverse weather conditions. Ambivalent means having mixed feelings or being unsure, which isn’t about desirability. Apply is a verb about putting something to use, and audible means something can be heard. So adverse is the word that best conveys the sense of undesired.
