In this task, you will be shown a conversation and a question. You should categorize the question into matching, summary, logic, arithmetic and, commonsense groups. Matching is a question entailed or paraphrased by exactly one sentence in a dialogue. The answer can be extracted from the same sentence. Questions that cannot be answered by the surface meaning of a single sentence belong to the reasoning category. We further define summary, logic, arithmetic and, commonsense subcategories. Answering summary questions requires the whole picture of dialogue, such as the topic of dialogue and the relation between speakers. We require logical reasoning to answer logical questions. in arithmetic questions Inferring the answer requires arithmetic knowledge. To answer commonsense questions, besides the textual information in the dialogue, we also require additional commonsense knowledge that cannot be obtained from the dialogue. Note that a question can be in more than one group. "W" and "M" in the conversations stand for "woman" and "man".
One example: W: The movie next Tuesday has been cancelled due to lack of interest. M: What do you mean? W: Well, by last night only a few tickets has been sold., Question: What can we conclude about the movie? (A) They want to buy the tickets for the movie. (B) The tickets for the movie were sold. (C) The movie will not be shown.
Solution is here: commonsense
Explanation: This is a good example. To answer this question we require commonsense knowledge that cannot be obtained from the dialogue. So, this is a commonsense question.

Now, solve this: W: Why don't we buy a car, dear? M: I have been thinking about it for a long time. I think it necessary for us to buy one. We live so far away from my company. W: Yes. With a car, you wouldn't have to catch a bus to work. It can save a lot of time. M: Sure, but we don't have enough money at present. W: Why not borrow some from the bank? I think we won't have to borrow so much now. M: Well, let's go down town and have a look., Question: Why do the two speakers want to buy a car? (A) They have a lot of money. (B) The man lives too far away from his office. (C) The woman's office is too far away from her home.
