Ex Input:
F: I'm really looking forward to going camping this summer, Jason. When I get into the forest, I feel like I can finally relax. It's better than any beach. ,M: Me too, Sarah. I can't wait to sit by a fire and sleep in the forest under the stars. The one thing I find stressful, however, is the packing. ,F: Why is that? ,M: We have to bring sleeping bags, clothes, food, water, games and so much more, but we don't have enough room in our car for extra stuff. It's really frustrating. ,F: That's why I want a car with far more enough space like Marie Antonis. They store all their camping things inside. ,M: Yeah, sounds like we have to save up money for a new car.
(A) F: Marie wants a new car like ours, which can store almost everything. (B) F: Just a minute! I do not quite follow what you are saying, would you mind repeating that? (C) F: Tony, we already have a big car. You don't need to buy a new one. (D) F: You agree, right? I've been looking for an appropriate new car.
