Is Caleb is baking pies for the bake sale a compound predicate or complete predicate?

Here's why:

* Complete Predicate: The complete predicate includes the verb and all the words that modify the verb. It tells us what the subject is doing or being.

* Compound Predicate: A compound predicate has two or more verbs that are joined by a conjunction (like "and", "or", "but").

In this case, "is baking pies for the bake sale" is the entire predicate that tells us what Caleb is doing. There's only one verb ("is baking").
