Transitive verbs come in two forms, active and passive. In a sentence with a passive verb, something is done to the subject of the sentence. Transitive active verbs must have a direct object. The subject does something to the direct object.
If a sentence has only a subject and verb and a prepositional phrase, it cannot be transitive active.
