Input: Consider Input: F: Mr. Sharp, thank you for giving me this interview. So, my first question is, are you happy with your life? ,M: Am I happy? You may know you are the first person to have asked me this question directly. The others dared not because they were afraid I might say yes. They wanted me to say no so that they could make up stories about me. ,F: What kind of stories? ,M: Brian Sharpe, author of over 100 historical novels, lives in a lonely house 30 miles away from Sydney. But is he happy? (?). ,F: Is that why you have refused many interviews? ,M: I'm tired of being told that I must be unhappy because I'm rich and successful. I'm not unhappy. ,F: Understood. And I'm wondering if you follow a similar pattern of writing. ,M: I know what you mean. Do I write similar stories? I say no. ,F: So, how do you create your heroes? ,M: My heroes live? They think for themselves. All their stories are drawn from life, my life, my friends' lives, including my friends in many books. ,F: Sounds good to me.
(A) M: Thanks, following a fixed pattern is a tedious job and I want something brand new. (B) M: I am sorry. You spoke so rapidly that I did not catch the meaning of what you said. Could you repeat that? (C) M: I don't like follow a fixed pattern but I want to follow the non-realistic writing style.
