The correct answer is:
<span>[O say what stranger cause, yet unexplor'd,
Could make a gentle Belle reject a Lord?]
The poet is wondering why a girl would ever reject a man who is hitting on her and wants to marry her. It is implied that women had no say in this - that their marriage depended solely on the man and that they couldn't choose at all. The entire poem is quite satirical and meant to mock these kinds of ideas and behaviors.

By giving a speech in an American University, in April 1965.
The definition of communal is "Shared by all members of a community; for common use."
I would say that their kitchen <em>is</em> communal because their "community" consists of all the roommates who use the kitchen and contribute to it. If only one person contributed to the kitchen stock, then it would not be communal.
