Example Input: M: I'm talking to Jackie Gold, who is a very proud mother. Her daughter Olyvia, appeared on the stage of London Palladium Theater in the musical, the Sound of Music last month. So how did it all come about? ,F: Well, until last year, the idea of her appearing at the London Palladium would have been unthinkable for our family. Things started to happen when Olivia got the leading role for the show Annie at the local theater. For Annie, Olivia had to learn more than 200 lines. She was on stage from most of the 2 hours show. I decided that we do 10 pages a night. After memorizing it, I gave her a line and she would have to tell me what the next line was. She picked it all up even better than her homework.
(A) M: Just a minute! I do not quite follow what you are saying, would you mind repeating that? (B) M: Wow, she got the role for Annie at the local theater seven years ago, but she had to learn more than 200 lines for Annie, right? (C) M: Do you mean although she got the role for Annie at the local theater last year,she was on stage from most of the 4 hours show? (D) M:  So she got the role for Annie at the local theater last year.
