PASSAGE

The teacher gave _____ feedback that helped students improve.

Which choice completes the text with the most logical and precise word or phrase?

A. brief
B. constructive✓ Correct
C. negative
D. vague

Detailed Answer Explanation

Choice B is the best answer. "Constructive" is correct because it means "serving a useful purpose; helpful." The context clues in the passage indicate that this meaning best completes the sentence logically.

Why others are wrong: A ("Brief" means "short," which doesn't fit the context.), C ("Negative" means "expressing disapproval," which doesn't fit the context.), D ("Vague" means "unclear," which doesn't fit the context.).
