You can solve the problem of a logically mismatched subject and predicate—called faulty predication—by rewriting either the subject or the predicate so that the two fit together.
To test a sentence for faulty predication, ask yourself whether the subject can do what the predicate says: For example, do schools behave? If not, revise the sentence.
Revise the subject so that it can perform the action described in the predicate.
Revise the predicate so that it fits logically with the subject.
