Dialogue: M: Let's try that song again. You played it well, but try to play the second part a little faster this time. W: Ugh. I already played it three times! My hands are too cold to play well. M: OK, let's try another song. Play the short, slow piece that you like so much, the one that sounds like guitar music. That should warm up your hands! W: Oh, that one is easy! I played it four times this morning. It's my favorite. M: Good! You will be a great piano player one day if you keep playing the songs that you enjoy! Question: What instrument is the woman playing? - The guitar. - The violin. - The piano.

Dialogue: M: Can I help you? W: Yes, well, I bought this tie last week for my husband's birthday, and er...well he doesn't like it. Could I change it for something else, such as a shirt or a hat? M: Certainly, madam, provided that it hasn't been worn, and if you have the receipt. W: Yes, here it is. M: OK, er... this tie looks as if it were worn. I'm afraid I can't put that back on the shelf. W: Oh, that's a pity. Question: Why did the assistant refuse to help the woman? - Because the woman didn't show him the receipt. - Because the thing she wanted to change had been worn. - Because the woman told a lie.
(A).
Because the thing she wanted to change had been worn.

Dialogue: 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. 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. Question: How did the second stage of the experiment differ from the first stage? - Only one dolphin was able to see the light. - The male dolphin received more rewards. - Both dolphins were put in the same tank.
(A).
Only one dolphin was able to see the light.
