Answer:
them: I folded them neatly and put them in my drawer.
It: It still looked pretty and new.
Step-by-step explanation:
The pronoun them might refer to more than one antecedent:
"I found receipts in a few of my jeans. I folded them neatly and put them in my drawer." (The pronoun them might refer to receipts and jeans.)
The pronoun It also might refer to more than one antecedent:
"I found an old box decorated with ribbons and a pink bow. It still looked pretty and new." (The pronoun It might refer to a box and bow.)
So these two pronouns in the paragraph have unclear antecedents.
