least favorite stuff is having to put the mask on every now and then and there are lots of pop quizes and homeworks hahàhaha yup

the pronoun reference replaces a noun, but you have to make sure there's no room for confusion.

in the first sentence "her" could be referring to shely or to the sister. the answer there is "shelly called her sister and told her about the new baby."

in the second sentence "it" could be referring to the roof or the floor. the answer there is "since the roof leaks on the family room floor, we need to repair the roof."

i'm thinking it would be when compound subjects are joined by or, nor,either-or, neither-nor.
