Select the most appropriate option to improve the bold part of the sentence.
He did not knew the answer.
Show answer & explanation
Correct answer: B
Explanation
The most appropriate option to improve the bold part of the sentence 'He did not knew the answer' is ‘know’.
Explanation:
In English grammar, when using the auxiliary verb 'did' (the past tense of 'do') to form negative sentences or questions, the main verb must always be in its base form (infinitive without 'to').
Correction: The past tense is already indicated by 'did,' so using another past tense verb like 'knew' is a grammatical error known as a double past.
Correct Sentence: He did not know the answer.
