Example Input: F: OK, I think we have 2 choices of where we can spend our vacation. The first place is a little house. It's located on a fruit farm. But it says there is no air conditioner. ,M: That's OK. It's on the rainy side of the island. It's cooler there. ,F: You're probably right. But there is no washing machine or dryer, not even a TV. ,M: Oh no, no TV? That's terrible. What's our second choice? ,F: It's on the opposite side of the island, a very nice place with a big swimming pool. It's only 3 blocks from the ocean and the pool area also has a beautiful garden. ,M: Wow, it does have everything, washing machine, dryer, TV, refrigerator. All we need is our toothbrushes. Let's go with the second choice. I can't wait to go.
(A) F: I’m sorry, I didn’t catch that. Would you mind speaking more slowly? (B) F: Yeah, it does have everything, washing machine, dryer, TV, and refrigerator. And it has a big swimming pool! (C) F: Really? You mean we don't need our toothbrushes because the second place provides toothbrushes? (D) F: Well, although it doesn't have washing machine, dryer, TV, or refrigerator, it has a big swimming pool!

Mister Lee is a successful inventor of a popular smartphone app. ,M: Thanks for having me, Miss Smith. ,F: We're glad you could take the time. Now, how does it feel to be so successful at such a young age? ,M: Well, I sometimes feel a little worried and it's hard running a new company. ,F: You have your own company? Great, then surely you must feel proud to have done so well so quickly. ,M: Well, I'm probably the only 19-year-old in the millionaires club, and thank you for this opportunity to speak here, Miss Smith. I didn't really know I could speak to so many people without getting nervous.
(A) F: Why are you proud to speak to so many people? You are already 25 years old, aren't you? (B) F: It's normal for you to be scared to speak to so many people because you are only 22 years old.
