You know, I am very fond of playing chess. ,F: Now, many college students do a part time job to earn some pocket money. What do you think of that? ,M: Well, it can really help us earn some money and gain some experience, but I am afraid it would take up too much study time.
(A) F: I think so. Part-time jobs only take up little study time, but the return is huge. (B) F: I agree. Part-time jobs are so time-consuming that nobody now ever thinks of that. (C) F: Just a minute! I do not quite follow what you are saying, would you mind repeating that? (D) F: You think part-time jobs can help one to study, while they take up little study time.

Example Input: M: Oh no, what happened in here, Alexa? Why are there some dead plants? ,F: I know. Every planned comes in alive and ends up dead. I definitely do not have a green thumb. ,M: People always say that, but it's not that hard to keep house plants. What did you do to care for this one? ,F: That one had a big flower on it, so I put it in the sunlight. ,M: This is a winter plant from North China. It doesn't do well in direct sunlight, just move it here. Didn't you look up how to care for it when you got it? ,F: No, I just thought it was pretty and it was doing OK in the shop. ,M: And this one here is all yellow, that means you gave it too much water.
(A) F: You mean I watered it too much that it turned yellow? I thought it needed water. (B) F: I am really sorry, I did not catch that. Would you slow down, please? (C) F: This yellow one was the only plant that I put in the sunlight. I thought I did it right. (D) F: Too much water for it? But it came in yellow and dead. I was watering to save it.
