Identify the part of the sentence that contains a grammatical error.
Only in the final manuscript (1)/ did the theorist (2)/ acknowledges the limitations (3)/ of his earlier hypothesis. (4)
Show answer & explanation
Correct answer: C
Explanation
Correct Answer: (3)
Explanation
• When an auxiliary verb such as did is used in a sentence, it must be followed by the base form of the main verb (V1).
• In this inverted structure triggered by the restrictive adverbial phrase "Only in...", the auxiliary did precedes the subject "the theorist". Hence, the main verb must be acknowledge instead of acknowledges.
• Corrected Sentence: Only in the final manuscript did the theorist acknowledge the limitations of his earlier hypothesis.
