1 Pay all that money for a movie ticket? 2 You must be joking. 3 No, I'm not, and I don't begrudge the high price. 4 It may be cheaper to rent a DVD, but I'll go to the theater any day. 5 There's no substitute for the big screen and surround sound. 6 Seeing a movie in a theater makes the story larger than life. 7 Another advantage is that I get the full impact of special effects. 8 And third, it gives me a chance to socialize with friends. 9 These are the three reasons I will discuss in my essay. Which statement best describes sentence 9?
A.It is unnecessary; it is repetitive and tells rather than shows readers what will be discussed in the essay.
B.It is necessary; it summarizes the essay.
C.It is necessary; it clearly announces the writer's purpose.
D.It is necessary; it summarizes the thesis statement.
