Explanation
PASSAGE
The mayor's _____ speech inspired citizens to volunteer for community service projects.
Which choice completes the text with the most logical and precise word or phrase?
A. quiet
B. powerful✓ Correct
C. confusing
D. brief
Detailed Answer Explanation
Choice B is the best answer. "Powerful" is correct because it means "having great effect or influence." The context clues in the passage indicate that this meaning best completes the sentence logically.
Why others are wrong: A ("Quiet" means "making little noise," which doesn't fit the context.), C ("Confusing" means "difficult to understand," which doesn't fit the context.), D ("Brief" means "lasting only a short time," which doesn't fit the context.).
