Explanation

• The correct punctuated sentence is:"She's been known to sing beautifully," commented Ali
• Quotation marks must enclose the exact spoken words: "She's been known to sing beautifully"
• A comma is used to separate the quotation from the dialogue tag (commented Ali).
• The comma always goes inside the quotation marks.

Explanation

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".
