Ex Input:
M: Would you consider buying a self-driving car? ,F: I don't know. I guess I'd have to research a bit more about them before making that decision. ,M: It will probably be a while before we are able to buy them anyway. We might be seeing self-driving trucks on the road pretty soon, though. Google wants to change the commercial trucking industry. Right now, there are over 3 million truck drivers in the US, so adding self-driving trucks would likely take away a lot of jobs. But many drivers might still be able to accompany their trucks and get a full night's sleep in the process. ,F: Truck drivers cause a lot of accidents on the freeway, so I think I'd like to see self-driving trucks. It would make me feel safer on the road. ,M: Really? I think it might make me feel less safe. A human driver is much more likely to react quickly to something unexpected.
(A) F: I am not agree with you, I don't think they are safer. (B) F: I am really sorry, I did not catch that. Would you slow down, please? (C) F: I am not excited by their speed because I think they are not safe at all. (D) F: Are you serious? I don't understand why you feel scared by them.

So what is your child's name? ,M: Megan Jones. ,F: Let's see, um, she missed the last couple of days has she been sick? ,M: No, she's been having some problems with the other kids in your class. ,F: Well, you know, junior high school is the difficult time, but she just needs to speak up a little more in class. ,M: No, it's more than that. Some of the kids in your class have been joking around with her a lot about her appearance. And then the other day, you didn't help at all. She said, you commented on her blouse and jeans. Saying they were from the nineteen seventies.
(A) F: You're right. I will find out who stole her phone. And the kids really like Megan's appearance. She is like an angel. (B) F: I think the kids didn't ignore her at lunch on purpose, because they really like Megan's appearance. She is like an angel. (C) F: I understand. I won't let them make fun of her appearance.
