Concept:In emphatic stress, the capitalized word is the focused answer.
The correct question must contrast that word with another possibility.
Explanation:The given sentence emphasizes “DECEMBER.”
So, the question likely asked about a different month, not December.
Option D asks: “Did the workers agree to forgo their March salaries?”
The natural answer correcting that question is: “They agreed to forgo their DECEMBER salaries.”
Thus, the word “March” directly contrasts with the stressed word “December.”
Hence, option D is the appropriate question.
Answer:D. Did the workers agree to forgo their March salaries?
