Answer 1

Hmm. It's not strictly grammatical to us a singular verb with a plural object, but we do say "favorite food is cookies" or "fruit is pears" in casual speech. 1 and 3 are more proper, as is 4-1. 4-2 and 4-3 are not proper at all. The correct verb would be "are", not "is."

5 and 6 are both proper, but 5 would be more commonly used.
