Sorry, Ms.Sue, when I posted my answer, yours didn't show up on my computer yet, or I would not have answered that post.

That's o.k., E.G. It's tempting to answer these easy questions. :-)

Thank you, Ms. Sue!

In the given sentences, "I" and "me" are pronouns. The pronoun case refers to how the pronoun is used in the sentence, specifically whether it is functioning as a subject or an object.

In sentence 20a, "I" is in the subjective case. It is used as the subject of the sentence, along with "My best friend". When a pronoun is the subject of a sentence or clause, the subjective case is used. For example, "I am going to Hawaii."

In sentence 20b, "me" is in the objective case. It is used as the object of the verb "are going". When a pronoun is the object of a verb or a preposition, the objective case is used. For example, "My best friend and me are going to Hawaii."

To determine which pronoun case is correct in a sentence, you can try removing the other person or entity and see if the pronoun still makes sense. For example, in sentence 20a, if you remove "My best friend" and say "I am going to Hawaii", it still makes sense. Therefore, "I" is correct in this case. In sentence 20b, if you remove "My best friend" and say "Me am going to Hawaii", it does not make sense. Therefore, "me" is incorrect in this case.

In summary, the correct pronoun case in sentence 20a is "I" (subjective case) as it is the subject of the sentence. The correct pronoun case in sentence 20b is "me" (objective case) as it is the object of the verb "are going".
