Maybe because number two is for losers and 1st place is the only way -\ -_-/-
"Predicate nominative" is the one among the following choices that are given in the question that shows the kind of complement the word SHORELINE is.
We know this when we see that she sees what kind of clothes does Mrs. Wright have to wear, what her kitchen looks like, what her broken stove is like, and generally how bad the standard of living was in the Wright household.This is like that when is stated in the story that Mrs. Wright was not happy there because Mr. Wright killed her love of singing. Hope this can help
