(singular "everyone" takes the singular pronoun "his or her", but using "their" as a singular gender-neutral pronoun has become more common and accepted)
51. You and I are going to the store together.
("You and me" is incorrect; when the pronoun is the subject of the sentence, use "I" instead of "me")
52. I will not call on anyone who is not raising their hand.
("Whom" is incorrect; use "who" as it is the subject of the verb "is raising")
53. Did you see the way she looked at her?
("Her" is correct; "she" is the subject form of the pronoun, while "her" is the object form and is correct in this sentence)
