What does the following line foreshadow? "Women only do that (call each other sister] when they have called each other a lot of other things first."

the punctuation used in this line was exclamation points. exclamation points can show excitement, anxiousness, and etc.

in the following paragraph, the fourth sentence the correct answer is: three personal subject pronouns

”she was embarrassed when she found that they had been put back on the shelves…”

a   subject pronoun is a personal pronoun. i, you, he, she it, we, they.  

in the sentence it can be observed she, used twice and they used once. is for this reason that is a three personal subject pronoun sentence.
