Input: Consider Input: F: What are you doing? ,M: I'm working on my college application. I just started writing my personal statement, but I'm having a hard time. ,F: What does it have to be about? ,M: It's basically just an essay about why I want to go to college and what I hope to do there. It's difficult to write, because I don't know what to major in yet. I know I want to go to college. I just don't have an idea of why I want to go. ,F: Why not just tell the truth in your essay? ,M: You mean I should write about the fact that I don't know what to do with my life? ,F: Yeah. I mean, I doubt if anyone really knows what career they want to have when they first go to college. You have years to figure that out. ,M: I guess I could write about that. ,F: What else do you need to do to finish your application? ,M: I need 2 recommendation letters. I asked my English teacher and my math teacher. Mrs. Watson turned hers in, but I'm waiting on my math teacher. I wanted to ask my drama teacher, Mr. Bennett, but I've only had one class with him, so I decided not to. I already turned in my grades and my SAT score.
(A) F: So, you need 4 recommendation letters and your drama teacher, Mrs.Watson, has given the recommendation letter to you? (B) F: Just a minute! I do not quite follow what you are saying, would you mind repeating that? (C) F: So, now your math teacher, Mrs.Watson, has turned hers in but now you are waiting on your Chinese teacher? (D) F: So, you have not turned in your grades and your SAT score? And now your are waiting on your English teacher, Mrs.Watson?
