Question

Identify the part of the sentence that contains an error:
He did not knew that the train had already left.

• A. He did
• B. not knew
• C. that the train
• D. had already left

Hint:

Grammar Tip: After auxiliary "did", always use the base form of the verb.

Answer 1

The Correct Option is B

Solution: The sentence in question is: "He did not knew that the train had already left." The error is found in the phrase "not knew." 

Explanation: In English, when forming the past tense in negative sentences with the auxiliary verb "did," the main verb should be in its base form. Therefore, "knew" should be changed to "know" as "did" already indicates past tense. The correct phrase should be "did not know."

Corrected Sentence: He did not know that the train had already left.

Answer 2

The sentence in question is: "He did not knew that the train had already left."

The error lies in the construction "not knew."

The sentence uses "did" which is the auxiliary verb indicating the past tense. Therefore, the main verb should be in its base form. The correct usage should be "not know."

Corrected sentence: "He did not know that the train had already left."
