Based on the sentence, what does the word opprobrium most likely mean?

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."

well there are a bunch of different possibilities so your gonna have to be a bit more specific

it took the same time to travel by as it did on   train : ) hope i
