Help the exhausted student ask their roommate to lower the volume so they can sleep. Select ALL the grammatically correct and polite ways to say this.
The correct answers are Would you mind turning down the music? and Do you mind turning down the music?
When using "mind" to make a polite request for someone else to do something, it must be followed by a gerund (-ing form). "Would you mind to turn..." is grammatically incorrect. "Do you mind if you turn..." sounds very unnatural compared to just asking them directly!
