We would need the book or the story to be able to do this one.
The answer would be A. An attention grabbing sentence.
Answer:
LOL hahahahahahhhahahahah
From the answers given.
I would go with D, as Non-fiction isn't locked to politics or science; It's moreover use to categorize literature (books, etc...) that are based solely on fact.
I believe the answer is C. You can brake that sentence into to two sentences and it will flow better.
Hope that helps! :)
