Question

what is the meaning of the word mercurial as used in the passage? the dj on our college radio station is known for his unpredictable taste in music, sampling everything from classical guitar to heavy metal to reggae. when i interviewed him for the school newspaper, i learned that his musical choices mirror his mercurial temperament; our conversation was like few id ever had. creative or artistic passionate or excitable changeable or variable

Explanation:

To determine the meaning of "mercurial", we analyze the context. The DJ has "unpredictable taste in music" (sampling various genres) and the musical choices mirror his temperament. "Changeable or variable" fits as unpredictable implies variability. "Creative or artistic" doesn't relate to unpredictability, and "passionate or excitable" doesn't match the focus on variability.

Answer:

changeable or variable
