Explanation

"She's been known to sing beautifully", commented Ali.

Quotation marks are used to enclose the exact words spoken, which are: She's been known to sing beautifully.

The speaker (Ali) comes after the quote, so the quotation marks begin and end around the spoken words.

Explanation

اگر مجھے اس کا نام معلوم ہوتا تو میں آپ کو بتاتا

The second part of the sentence is in the past tense.

The verb to be used should also be in the same tense.

The past tense of the word "know" is "knew".

Therefore, the correct tense here is past tense and the verb used is "knew".
