input: Please answer the following: W: Well, I hope so. You see, I can't find my handbag with my mobile phone and some books in it. I've tried everywhere. M: Were they the only things in the bag? W: Well, no. My front door key as well. M: I'm afraid, madam, we're not having much luck. When did you last have your bag with you? W: I haven't seen it ever since I went shopping this morning. I went by car and stopped outside the tailor's. I had my mobile phone with me then. I think I put it in my bag but I'm not so sure. M: Did you ask the tailor? W: Yes, and I've also been back to the shopping center. M: So you didn't buy anything at the shopping center? W: No. Well, I've checked there...oh, dear. I've been awfully silly. I think I've left the bag there. What was said before this conversation?

Please answer this: W: Yes. I went to New York to attend a summer course in English. M: Wow. You were lucky. How long did you stay there? W: About 50 days. I went there on July 5th and came back on August 25th. M: How about the course? W: The course was very good. The teachers were nice. They taught us to listen, speak, read and write in English, but it was mostly speaking. One interesting thing I found was that the American classes are different from our classes here because the students have a lot more freedom. You can sit anywhere you like in the classroom. You can ask the teachers questions at any time during the class, and you are welcome to share your ideas with the class. I really like this kind of class. M: How interesting! Maybe our teacher should try that. What was said before this conversation?

Problem: Given the question: M: That's good. Now what should we do? W: We need to plan the menu. M: Oh, that's right. What do you have in mind? W: I think I'm going to make the chicken salad we had at our 39th wedding anniversary. Remember, I asked Thomson, the chef of the restaurant where we often go, for the recipe? M: Oh, yes. I remember. Time sure flies! Now we are celebrating our golden anniversary! And Thomson was very friendly. You know, chefs seldom tell people their recipes. They often keep them a secret. W: I understand that. So you see, I have promised I will also keep the recipe a secret. M: Well, Thomson will appreciate that. Oh, but did you forget that Linda doesn't eat chicken? W: Linda? Oh, my Gosh! I forgot to invite her! She'll be mad at me. It just slipped my mind. Thanks for reminding me! I think I'm getting old! M: Looks like you are! What was said before this conversation?
