Answer 1

A predicate nominative is a is a noun (and can be a pronoun too, like she or him) that comes after the verb and renames the subject.
Examples (predicate nominative is in all capital letters):
My coach is a very fair MAN.
Aimie was the GIRL who took care of me.
So, where is the subject renamed here? I'll give a hint - the subject is "pet".
