Concept:In emphatic stress questions, the capitalized word is the focus of contrast. The correct question must contain a contrasting word in the same position as the stressed word.
Explanation:The stressed word is "REBUKED", a verb.
So the appropriate question must contrast this verb with another verb.
Option B asks: "Did the principal commend the teachers for lateness?"
Here, "commend" contrasts with "rebuke", making the given sentence the correct answer: "No, he REBUKED them."
The other options contrast a noun or phrase, not the verb "rebuked".
Therefore, Option B is correct.
Answer:B. Did the principal commend the teachers for lateness?
