Which word means 'to oscillate between opinions or positions'?

• A. Tacit
• B. Vacillate
• C. Tirade
• D. Torpor

Answer: (B)

This item tests your grasp of a verb that describes moving back and forth between opinions, showing indecision. Vacillate means to waver between different positions or choices, to hesitate and shift one’s mind repeatedly. It captures that inner back-and-forth feel of not settling on one stance. For example, you might vacillate between accepting a job offer and waiting for a better opportunity, weighing the pros and cons over time.

The other words refer to unrelated states: tacit means understood without being stated; tirade is a long, angry speech; torpor denotes sluggishness or lack of energy. None of these convey the sense of oscillating between viewpoints.
