Input: Consider Input: M: Well, any luck? Did you see Buster anywhere? ,F: No, I couldn't find him either. I drove all around the neighborhood. I circled our block 3 times, hoping he'll show up. No such luck. I'm sorry, Ben. ,M: It's not your fault. I shouldn't have left the door open. I hope we'll find him. He is such a huge part of our family. He walks with Lily to school every morning. ,F: I'm sure we'll find him. Ben, I remember when I lost my dog, Spot. We looked for 10 hours and finally we just gave up. Not long after we got home, Spot showed up at our front door. They know how to get home, Ben. They always do. ,M: I hope you're right, Lucy. Maybe he'll show up before it gets dark. I just hope he's OK. ,F: He will be, Ben. He has always been loyal to you and your family. He's probably just off exploring.
(A) M: I really hope so. By the way, thank you for helping me looking around our neighborhood. (B) M: I'm just worried. As a neighbor, I know you never raised a dog, so you won't understand it. (C) M: Just a minute! I do not quite follow what you are saying, would you mind repeating that? (D) M: It's fine, Lily. You may leave the office now and pick up your son Buster from his school.

Output: A


Input: Consider Input: M: Universal Travel Agency, may I help you? ,F: Yes, my husband and I want to take a vacation to an island somewhere. Do you have any places to recommend? ,M: Certainly, off the top of my head. I would suggest the island of Bali. ,F: Why Bali? ,M: At this time of year. Most places have a lot of rain, but it is the dry season in Bali. There are also many excellent restaurants and hotels to choose from, plus, Bali is known for its surfing and diving, and I must say that the shopping is absolutely great. ,F: That sounds amazing. Jason loves to dive, and I love to shop and eat. Can you tell me how much it will cost for the two of us?
(A) M: You parents and you, that's 100 dollars, but don't worry, your friend Jason in Bali is also our company's employee, so you can give the money to him when you get there. (B) M: I didn’t hear you. Please could you tell me again? (C) M: You and your husband Jason, right? You need to pay for 500 dollars for your trip to Japan. (D) M: You and your husband Jason, right? You need to pay for 100 dollars.
