Well I'm going to be 1 point from being broke after this but here's some free points.

I feel bad now we'll try again next time

try to save your points when you need em

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."

sorry but can you explain the question because i didn’t understand it
