In many muslim cultures, men and women follow rules a) how much wine to drink. b) whether to donate to the poor. c) where they are allowed to live. d) how to interact with each other.

Hey there!
The answer is D. In the old times, and even now, women have to cover their faces, and they usually can't make eye contact with men. Mirrors were often used to fix this, allowing the woman to see the man without making eye contact, as that was deemed disrespectful.
Although this is highly controversial, people are doing their best to make the world is a better place. We can either help, or watch, right?
Hope this helps!
