2. The of a sentence is the person, place, thing, event, etc. being
described or referred to in a sentence.
a. subject
b. article
c. clause
d. predicate

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."

the answer should be the first one. "many people find his lyrics very moving."

it by far makes the most grammatical sense and is very objective, removing any first person from the original sentence and keeping with the sentence fluency.
