Explanation: A complete sentence expresses a complete thought. The sentence needs to have a subject and a verb. The only sentence that is a complete thought and has both a subject and a verb is "The students in the class learned about the rainforest today. " The subject is "students" and the verb is "learned". The other answer choices are sentence fragments, meaning they do not express a complete thought.
