Identify the segment in the sentence which contains a grammatical error.
He wondered what was the reason for her refusal to accompany him.
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. was the reason.
The segment in the sentence which contains a grammatical error is "was the reason." In this construction, the verb "was" is redundant when paired with the question word "what."
The correct structure would be to remove "was" and place it after 'reason'.
Alternatively, the sentence could be rephrased to "He wondered what the reason was for her refusal to accompany him." This maintains the same meaning while correcting the grammatical error.
