Answer:
In the sentence "If that is cherry pie, I will eat it for my dinner," there are two simple predicates (verbs):
1. "is" - This is the simple predicate of the subordinate clause "that is cherry pie."
2. "will eat" - This is the simple predicate of the main clause "I will eat it for my dinner."
Each of these verbs functions as the main action or predicate in its respective clause.
