Help the secret agent complete her mission report by choosing the grammatically correct word.

The mysterious stranger handed the top-secret envelope to my partner and ___.

The correct answer is me.

Because the pronoun follows the preposition "to," it acts as the object of the preposition. Even though it is part of a compound object ("my partner and me"), you still must use the object pronoun me, not the subject pronoun I. (A good trick is to remove "my partner and" to see what sounds right: handed the envelope to me).
