Final Answer:
The change needed in sentence 4 is B) Change answers to answer
Step-by-step explanation:
In sentence 4, B) the change needed is to replace "answers" with "answer." The correct sentence should read, "She asked me a question, and I gave her a detailed answer." The singular form "answer" is more appropriate here, as it aligns with the singular noun "question" in the sentence.
In this context, the use of "answer" instead of "answers" ensures subject-verb agreement, maintaining grammatical correctness. The sentence structure requires a singular form to complement the singular nature of the preceding noun. Therefore, the correction improves the overall coherence and precision of the sentence.
Ensuring proper subject-verb agreement is fundamental in constructing grammatically sound sentences. When discussing a single question, it is essential to use the singular form "answer" to match the singular noun it corresponds to. This adjustment enhances the clarity of communication, allowing the reader to grasp the intended meaning without encountering grammatical inconsistencies.
