Please answer this: M: So how did he do it exactly? W: Well, first of all, he kept the two dolphins together in the same tank and taught them to press levers whenever they saw a light. The levers were fitted to the side of the tank next to each other. If the light flashed on and off several times, the dolphins were supposed to press the left-hand lever followed by the right-hand one. If the light was kept steady, the dolphins were supposed to press the levers in reverse order. Whenever they responded correctly, they were rewarded with fish. M: Sounds terribly complicated. W: Well, that was the first stage. In the second stage, Doctor Bastian separated the dolphins into two tanks. They could still hear one another, but they couldn't actually see each other. The levers and light were set up in exactly the same way except that this time it was only Doris who could see the light indicating which lever to press first. But in order to get their fish, both dolphins had to press the levers in the correct order. This meant of course that Doris had to tell Bass whether it was a flashing light or whether it was a steady light. M: So did it work? W: Well, amazingly enough, the dolphins achieved a 100 % success rate. What was said before this conversation?

Answer: W: One of the most interesting experiments with dolphins must be one done by Doctor Jarvis Bastian. What he tried to do was to teach a male dolphin called Bass and a female called Doris to communicate with each other across a solid barrier.
Problem: W: Oh, yes. In the United States, we don't have to carry a big school bag with us like you do. M: Why is that? W: We have a locker of our own, which is a small box with a lock. We keep textbooks and our personal things in it. I just bring a day-pack to school. M: A day-pack? W: Yes. It's a small bag that you carry on your back. M: What do you carry in it? W: My notebooks or a few books for homework. M: That's convenient. Is there anything else you've noticed about our school? W: Yes. I am surprised that everyone is so silent in class. M: What do you mean? W: Well, we usually ask questions about exams, homework or textbooks on the first day of the school year. The teacher likes such questions. M: So you felt it different. W: Yes. I expected to see a lot of discussions in class, because we learn in that way in the United States. M: I see. That would be a good topic for our school newspaper for the first month of the term. Nice talking with you. See you around. Bye. W: Bye. What was said before this conversation?

input question: Tenant: Well Mr. Nelson. That's what I would like to talk to you about. (What?) Well, I want to talk to you about that noise! (Oh) You see. Would you mind talking to the tenant in 4B and ask him to keep his music down, especially after 10:00 o'clock at night? Apartment Manager: Ohhh. Who me? Tenant: Why yes. The music is blaring almost every night, and it should be your job as manager to take care of these things. Apartment Manager: Hey, I just collect the rent. Besides, the man living there is the owner's son, and he's a walking refrigerator. (Well ...) Hey, I'll see what I can do. Anything else? Tenant: Well, yes. Could you talk to the owners of the property next door about the pungent odor drifting this way. Apartment Manager: Well, the area is zoned for agricultural and livestock use, so there's nothing much I can do about that. Tenant: Well, what about the .... That, that noise. Apartment Manager: What noise? I don't hear anything. Tenant: There, there it is again. Apartment Manager: What noise? Tenant: That noise. Apartment Manager: Oh, that noise. I guess the military has resumed its exercises on the artillery range. Tenant: You have to be kidding. Can't anything be done about it? Apartment Manager: Why certainly. I've protested this activity, and these weekly (Weekly!) activities should cease ... within the next three to five years. Tenant: Hey, you never told me about these problems before I signed the rental agreement. What was said before this conversation????
