Question

Which of the phrase given below the sentence should replace the word/phrase given in underline in the sentence to make it grammatically correct? If the sentence is correct as it is given and no correction is required, select 'No correction required' as the answer.
Why does he worry over petty matters is not known.

• A. he worries
• B. he did worry
• C. he does worry
• D. should he be worry
• E. No correction required

Answer 1

The correct option is A he worries

The sentence is in affirmative. So, it is wrong to use 'does + $V_1$'. We should use 'sub + $V_1$ + s/es' to make it correct.
E.g. Why he goes there is not known to me.
