Find the error, if any, in this sentence: "The exhibits in the basement of the Museum of Natural History changes every four months."
The error in this sentence is the word "changes", which should be "change". The verb "change" is modifying the subject of the sentence, which is "exhibits", not "basement" or "museum". "Basement" and "museum" are both objects of prepositional phrases which describe the subject "exhibits". They verb must always agree with the subject, so in this case, you should use the plural form "change" to match the plural noun "exhibits".

Choose the word that makes this sentence grammatically correct: "Who is going to the park with Kelly and (me/I)?"
The correct sentence reads "Who is going to the park with Kelly and me?". Here, "who" serves as the subject of the sentence while "Kelly and me" is the object. "Me" is an object pronoun and "I" is a subject pronoun, so you should use "me" in this sentence.
