Input: Consider Input: M: Hey Lindaï¼ did you get that letter about the new options for food service next year? ,F: Not yet, are there a lot of changes? ,M: There sure are, instead of paying one feet to cover all meals for the whole school year. We are now able to choose how many meals a week we want, and can contract just for that amount. We still have to pay the whole year at the beginning, but we can choose to buy 7, 10, 14 or 21 meals per week. They give you a card with a number of meals you get each week marked on it. ,F: That's a big change Tom, and a complicated system. ,M: Yeah, but it will be much better for people who don't eat 3 meals a day 7 days a week in the cafeteria, because they don't have to pay for meals they don't eat. ,F: So, what's the deal for those who do eat at school all the time? ,M: It better for them, too, because the more meals you contract for, the cheaper each one is. ,F: I see, it still sounds rather complicated. ,M: True, it took me several hours to figure it out. I decided to go with the 10 meal plan. ,F: Why is that? ,M: Well, I never eat breakfast and I often go away on weekends, so the 10 meal plan gives me lunch and dinner every weekday at a fairly low price, and I won't be paying for meals I don't usually eat.
(A) F: You are right. You will benefit from the changes next year. That is good. (B) F: That is true. You will benefit from the changes in our company. It is good. (C) F: I totally understand why you dislike the changes in our company. Do not be sad. (D) F: I am really sorry, I did not catch that. Would you slow down, please?

Input: Consider Input: M: Anna, I heard you're going to Brazil. The World Cup is already over, why are you going there? ,F: I'm going there for a vacation with my parents. My parents don't like watching football games, but they like Brazil. So we'll go there this summer.
(A) M: What is Robo Cup? Is that why you are going to America? (B) M: I’m sorry, I don’t understand. Could you say it again? (C) M: Oh really!? You and your family are going to Hawaii for vacation! (D) M: It' s so nice to take a vacation with family! Wish you have a good time!
