Example Input: M: Have you found any pairs of shoes that fit? ,F: Well, I like the black pair, but my heels kept slipping out of them. The second pair was comfortable, but the color didn't look good at all, and this pair is a little tight in the front...
(A) M: I think you should take the second pair. The more comfortable, the better. Besides, I don't think the color is ugly at all. (B) M: I think you should go with the third pair. You can put a shoe-pad in if the front part is a bit loose. (C) M: The second pair sounds a perfect choice. It's comfortable and also good-looking. (D) M: Excuse me, could you repeat the question?
