A: M: I'd better read one of the articles for our political science class.
Question: 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.
[Q]: W: Don't you see the price keeps going down these days? I insist that we wait some time so that we can save more money. M: You have a point there, but it is inconvenient for me with this broken mobile. Sometimes it powers off by itself. It really makes me very angry when I am talking with someone. W: In that case,you'd better buy a new one. M: Well, I'll buy one this evening after supper. W: All right. M: Let's go to the shop together so that you can give me some advice.
