Identify the simple predicate in the sentence below.

The best selling novel is unavailable for the next three weeks.

a) is

b) unavailable for the next three weeks

c) novel

The simple predicate is only the verb.

A. is

To identify the simple predicate in a sentence, you need to find the main action or verb that the subject of the sentence is performing. In this case, the subject of the sentence is "The best selling novel."

The verb or main action of the sentence is "is unavailable." The word "is" is a form of the verb "to be" and acts as a linking verb in this sentence. The simple predicate, then, is "is."

So the correct answer is a) is.
