choose the option that best answers the question from the options lettered A-D The Parents Teachers Association promised to build a CAFETERIA.

Analyze the question: The word CAFETERIA is in capitals, which signals emphasis. This is a question on emphasis (stress), where the capitalised word is the new or focused information. The question that best fits is the one that prompts that word as the answer, or one that contrasts with it.

The statement: "The Parents Teachers Association promised to build a CAFETERIA."

Concept: In emphasis and stress questions, the capitalised word is the part that answers the question. The rest of the sentence must be the same as in the question, and only the stressed item is what the question asks about. So the correct question should keep "The Parents Teachers Association promised to build" and ask about what was built (for example, "Did the PTA promise to build a library?"). The answer to that is "No, a CAFETERIA."

Check each option:

• A. "Does the alumni association promised..." This changes the subject (alumni, not PTA) and is ungrammatical ("Does... promised"). Wrong.
• B. "Does the school authority promised..." This changes the subject and is ungrammatical. Wrong.
• C. "Did the parents teachers association promise to build a library?" This keeps the same subject (PTA) and the same verb (promise to build), and changes only the object (library instead of cafeteria). It is grammatically correct (Did... promise). The emphasised answer, CAFETERIA, corrects "library." Correct.
• D. "Does the PTA promised to demolish..." This is ungrammatical and changes the verb. Wrong.

Answer: C. It is the only option that is grammatically correct and differs from the statement only in the focused word.

Tip: For emphasis questions, find the capitalised word, then pick the option that keeps everything else the same and changes only that word's slot. Also eliminate options with grammar errors such as "Does... promised," since after "do/does/did" the verb must be in the base form.
