The yellow one was my favorite. I had a best friend named Seema, whose family was even poorer than ours. We played and studied together, and spent the best days of our childhood laughing at the silly stories we made up. I was excited to show her my three beautiful new dresses. She loved them all and was happy for me, but tearfully explained to me that her father could only afford to buy her clothes for her birthday. I felt sorry, and then did something that surprised even myself: I asked her to pick out one of my dresses for herself. To my disappointment, she picked up my favorite--the yellow one. Please remember, I was only seven years. My heart almost popped out of my chest. But as she held it against her body, and I saw how brightly she smiled, I stopped feeling any hurt.

Problem: Write a multi-choice question for the following article, with the given choices and answer: Article: Movie fans know that their action hero Superman does not really fly.And, in the movie Superman Returns, another visual trick is played on viewers.The man they see flying is not real.He is what is called a virtual actor.The first step in creating this digital actor is to have a real person stand in a room called a light stage.A computer then captures the outlines and shapes of his face and records how they throw off light .Paul Debevec is with the Institute for Creative Technologies at the University of Southern California. "We can light them with very specially computer-controlled illumination and take photos of them from seven different viewpoints with high quality digital still cameras." Mr.Debevec is part of a team working to create computerized images of people, objects and environments that look and act real.The light stage permits actors to be turned into digital versions of themselves much like the blue creatures in the movie Avatar.The real world could soon be using a similar technology.Computer experts at the Institute are developing a 3-D video teleconferencing system.It would send a video image of a person into a meeting room.That image would be able to work with the people in the room, who would see it in 3-D without special eyeglasses.Paul Debevec says: "The person who is being transmitted to a remote location can actually look around at the people in the room and everybody in that room knows who they're looking at .And that's such a fundamental part of human communication." He believes the business world will begin to use3-D video teleconferencing in the next five years." It's also a medium with which young people today are particularly comfortable," he said.A demonstration of an interaction between an earthquake survivor and students may be possible in a year.In 10 years, we may be able to play 3-D video games without special glasses. Options: A To compare their different styles. B To explain 3-D film-making technology. C To attract more readers to watch3-Dfilm. D To describe the origin of 3-D film industry. Answer: B To explain 3-D film-making technology. Question:

A: Why does the author mention the movies Superman Returns and Avatar in the passage?

Problem: Write a multi-choice question for the following article, with the given choices and answer: Article: Put an ice cube from your fridge into a glass of water. You have a piece of string 10 centimeters long. The problem is to take out that piece of ice with the help of the string. But you must not touch the ice with your fingers. You may ask your friends to try to do that when you are having dinner together. There is a saltcellar on the table. You must use salt when you carry out this experiment. First you put the string across the piece of ice. Then put some salt on the ice. Salt makes ice melt . The ice round the string will begin to melt. But when it melts, it will lose heat. The cold ice cube will make the salt water freeze again. After a minute or two you may raise the piece of string and with it you will raise your piece of ice! This experiment can be very useful to you. If, for example, there is ice near the door of your house, you must use very much salt to melt all the ice. If you don't put enough salt, the water will freeze again. Options: A More than three minutes. B Five minutes or so. C Only one minute or two. D About ten minutes. Answer: C Only one minute or two. Question:

A: How long will it take to carry out this experiment?

Problem: Write a multi-choice question for the following article, with the given choices and answer: Article: A group of swimmers has described how a group of dolphins protected them from a group of white sharks off the coast of New Zealand. The lifeguards were on a training swim when they came across a group of great white sharks before the dolphins raced in to help. The swimmers were surrounded by the dolphins for forty minutes before they were able to make them safety back to the beach. It was an uncomfortable experience as they were circled by a group of white sharks, which came within a couple of meters of them. Lifeguard Rob Howes was in the water with a colleague and his teenage daughter. He said around half a dozen dolphins suddenly appeared and forced them to gather together. The mammals swam in tight circles to create a protective wall between the white sharks and the lifeguards as the great white sharks were under the surface. The swimmers said the dolphins were extremely upset and repeatedly slapped the water with their tails as if to try to prevent the white sharks from attacking them. It's a day they'll never forget, especially for one who was on her first day as _ They have no doubt that the dolphins acted on purpose to protect them. Researchers have said that they're not surprised. A marine biologist insisted that dolphins, which are considered to be one of the most intelligent mammals, "like to help the helpless." Options: A Two. B Three. C Four. D Five. Answer: B Three. Question:

A:
How many swimmers are attacked by the white sharks?
