Which term means changing rapidly and often?

• A. to begin
• B. Changing rapidly and often
• C. to swallow
• D. within the body

Answer: (B)

The concept being tested is vocabulary for describing frequent, rapid changes. The best choice is the one that states the meaning directly—“Changing rapidly and often.” That phrase is essentially the definition of volatility, which is used to describe things that swing quickly and unpredictably, like prices, opinions, or conditions. Using this option shows you recognize the trait being described.

The other options refer to actions or locations unrelated to change: starting something, swallowing something, or something happening inside the body.
