Input: Consider Input: M: Jane, your new play is going on next week, are you anxious? ,F: Well, I'm very pleased to have Malcolm Rush as a director. He doesn't care whether you're tired or not, he'll just continue pushing until every scene is simply perfect. You don't just learn the part. You live it, which takes away any fears you might have of not being able to persuade an audience, you're real. That's very important. ,M: Malcolm does have a reputation of being quite the ruler, no one dares speak their opinions are here.
(A) F: Well, I think it is important for actors like Malcolm to be open to changes. (B) F: Yes. He is serious about his work. I think it is very important to act like the real person. (C) F: Yes. He is a serious writer, but I think it is very important to act like the real person. (D) F: I am afraid I did not quite catch what you were saying. Please repeat it.

Input: Consider Input: F: International Travel Agency, may I help you? ,M: Yes, my wife and I want to take a holiday this winter, to someplace warmer. ,F: I understand. How long do you want to take? ,M: Only a week between Christmas and New Year. That's the problem, you see. ,F: There is no problem. We can find you a flight to Australia leaving at Christmas and coming back on New Year's Eve. And it will only cost $500 per person. ,M: Actually, we'd like to go somewhere nearer. $1000 is a lot to spend for such a short time. How about some places nearer with few tourists? ,F: Sorry, I don't think we have any at present. You should have come here 10 days ago.
(A) M: That's a pity. But $1000 is really expensive. (B) M: Just a minute! I do not quite follow what you are saying, would you mind repeating that? (C) M: That's a pity. $1000 is not expensive at all. But I like to go to China. (D) M: That's a pity. $1000 is not expensive actually, and we'd like to go somewhere further.
