Which word means to be indecisive; to waver back and forth?

• A. Vacillate
• B. Dispassionate
• C. Pragmatic
• D. Placid

Answer: (A)

Indecisiveness and wavering between options are being tested. Vacillate means to be irresolute and to swing back and forth between choices or opinions, often delaying a decision as you weigh one option against another. It captures that sense of hesitating and shifting between possibilities.

For example, someone might vacillate between accepting a new job and staying in their current position, taking time to decide rather than committing right away. The other words don’t fit that sense: dispassionate describes lacking strong emotion or bias, not hesitation; pragmatic emphasizes practicality and usefulness in dealing with a situation; placid means calm and undisturbed, not prone to changing one’s mind.
