Q: Write a multi-choice question for the following article, with the given choices and answer: Article: Dolphins are our friends. They can use tools to solve problems although they don't have hands. For example, scientists have ever found that a dolphin can make a shy eel come out of its hole with a dead fish. Dolphins use different sounds to exchange information with each other. Scientists in Hawaii have developed a sign language to give instructions to dolphins, and the results are amazing. They find that dolphins not only understand the meaning of individual words, but also understand the importance of word order in a sentence. Most animals enjoy playing -- but dolphins seem to like making their games as challenging as possible. On a beautiful day in 1997, scientists at a beach watched a little dog going into the sea and swimming towards the dolphins. To their surprise, the dolphins came up to the dog and then started throwing it into the air. The dog seemed to enjoy the "game" and continued playing with the dolphins for more than an hour. Dolphins live in a very different world from ours, but they are very good at our "IQ tests" . For example, they will jump out of the water when they hear a whistle noise. They do this because they will get a fish as a prize. There is still much to learn about these cute problem-solvers, but it is certain that watching a dolphin show is fun. ,. (5) Options: A Because they want to get a fish as a prize. B Because they enjoy playing on the water. C Because they want to play with other dolphins. D Because the dolphin keepers want them to come out. Answer: A Because they want to get a fish as a prize. Question:
A: Why do the dolphins jump out of the water when they hear a whistle noise?

Q: Write a multi-choice question for the following article, with the given choices and answer: Article: When you watch 3D movies or TV,you have to wear a special pair of glasses.The 3D glasses make the images from the screen look like they are there in the room with you. Three-dimensional,or 3D,means having three dimensions : width,height and depth.3D technology is based on the way the human brain and eyes work.Because the _ of a person's eyes are about 6.5era apart ,when we look at something,each eye sees it from a different angle .Our eyes send the two images to our brain,and the brain puts them together.The small difference between the image from the right eye and the image from the left eye allows us to see depth. When we view pictures and television in two dimensions,each eye gets the same information.That is because the image has no real depth,and there is only one of viewing it.So the goal of 3D technology is to get a different image into each of the viewer.It uses two film projectors.One projects a left eye image and the other projects a right image.The 3D glasses allow us to see a different image in each eye. While watching 3D films,we feel that we are in the same environment as the things we're watching.However,it also has its disadvantages.The 3D glasses work by controlling the amount of light that reaches the eyes.It makes the screen look darker.What's more,people with eye problems may get headaches if they spend too much time watching 3D movies,because their brains need to work harder to "read" the images. Options: A the exciting games B the special glasses C the dark screen D the image in the room Answer: B the special glasses Question:
