Question

What is the predicate?:

That boy should be studying for his math test tonight.

1. test
2. studying
3. should be
4. should be studying

Answer 1

4. Should be studying

Step-by-step explanation:

The predicate is the part of a sentence (or clause) that contains a verb, stating what the subject is doing, or describes the subject.

When we have a main verb and an auxiliary verb accompanying it, both of them together form the predicate. In the given sentence, we have a construction with a main verb to study and an auxiliary verb should: should be studying. If you chose just studying or should be as the predicate, that would be incorrect as those two options are not the complete predicate.
