Yes everything is correct except in #4 you should change "is" to "are".
I say C. Blind to the truth because I read a shorter version of that book before, and I remember that the duke thinks that Olivia actually like him but hides it. And how he gets mad when Olivia falls in love with Viola, thinking that she was a gentleman! Ha! ;D
Hope this helps and have a great day!
Your answer is gentle souls are often disguised by rough exteriors. The others do not cover the overall theme of the book. Yes some rich and poor kids do not get along, but that is not an overall lesson. Also how often did they walk home alone. The story does not revolve around that. Last, Cherry was not a main character, she was not a main part of the plot. So your answer is once again the first one, it goes with the overall plot of the story.
