Answer:"Me and Kelly are best friends." (page 1)
And,
"Karen was really nice." (page 1)
Explanation:
"Me and Kelly are best friends." can be removed. If you need to state that Kelly is your best friend, you could rewrite "We did everything together" to "We're best friends, and we do everything together."
"Karen was really nice." can be removed because this statement is unnecessary and doesn't add anything to the story, since Karen is not an important character.
(Also, the sentence, "After class, Kelly's mom, Karen drove us home" you don't really need to mention Karen's name since, as I said, she isn't an important character. "Kelly's mom" is enough of a description because she isn't mentioned again. So, I would rewrite the sentence as "After class, Kelly's mom drove us home.")
