input question: Write a multi-choice question for the following article: Article: In America, square dancing has been the most popular form of folk dancing since the early days. In early times, when men and women worked in groups to build a barn or harvest crops, they danced when the work was done. The music came from the violin for the most part, but if there was no one to play a musical instrument, clapping was used to produce the rhythm to which people dance. The early settlers danced in a store, in a barn, or in a farm kitchen. A square is formed by four couples who stand facing the centre of the square. Each couple stand on one side of the square, the boy on the left and the girl on the right. The caller is an important part of the dance, since he tells the dancers which steps to do. If the dancers do not know the steps, he teaches them. It takes time to learn to be a good caller, and good callers are always in demand . These are the names of some of the steps the dancers do: Form a square; Circle; Honour your partner; Swing your partner; Form a star. There are many more. As the callers tell the dancers what to do next, they move to form the pattern he calls. Large or small numbers of people can dance at one time. Sometimes 800 or 1,000 people may be dancing at the same time. Or there may be only one square of eight people. Special clothes are worn by some when dancing. This makes the dance more colourful to watch. The special clothes are different from place to place. Women often wear full skirts of various colours with a pretty blouse. Men have coloured shirts and western trousers that they wear only when square dancing. In some country areas, everyone wears his best clothes. Today in some parts of the United States you will find some schools, clubs, or groups square dancing for fun.???

Young people and their parents don't understand each other. The world has always kept changing. During the second century after Christ a wise man said, "Bury me on my face because in a little while everything will be turned upside down." There has always been a gap between generations, but more people talk about it now. Old Mr. Ellis thinks he understands what has happened. "When I was a boy, I thought the world was a beautiful place. My life was very pleasant. But when I was older, I learned about people who were treated badly, people who didn't have enough to eat. I wanted to help them, and I married a girl who wanted to help them, too. We went to meetings and talked a lot, but it didn't seem to make much difference. ""Our children grew up in a world at war. They didn't know when the fighting would stop. They wanted their children to have nice clothes and toys. They didn't want to think about the future. They thought nothing could be done about it." "Now I have grandchildren, and they have their own ideas. They are trying to make the world better. They are trying to help other people. They're making people listen to them. I am proud of their generation."???

input question: Write a multi-choice question for the following article: Article: To get cash out in the 21st century, you won't need a bank card, a PIN or even have to move a finger. You will simply have to look the cash machine straight in the eye, declares National Cash Registers, a multinational company that makes automated teller machines, or ATMs. NCR has shown its first example machine that is believed to be the future of banking. Instead of asking you for your PIN on a screen, the Super Teller-Stella for short, asks you orally through a loudspeaker to look straight ahead while an infrared camera turns to your head, then your eye, and finally takes an infrared photograph of your iris . For identification purposes, an iris picture is better than a fingerprint, with around 256 noticeable characteristics compared with 40 for fingerprints. This means that the chances of someone else being recognized in your place is about 1 in 1020. Once you've been identified, Stella greets you by name and says: "Would you like cash or a statement?" An infrared port allows the machine to send a bank statement straight to your pocket computer.???

input question: Write a multi-choice question for the following article: Article: Certainly no creature in the sea is stranger than the common sea cucumber . All living creatures, especially human beings, have their features, but everything about the little sea cucumber seems unusual. What else can be said about an unusual animal that eats mud, feeds almost continuously day and night but can live without eating for long periods, and can be poisonous but is considered eatable? For some fifty million years, in spite of all its strange features, the sea cucumber has lived on its diet of mud. It is adaptable enough to live attached to rocks by its tube feet, under rocks in shallow water, or on the surface of mud flats. Common in cool water on both Atlantic and Pacific shores, it has the ability to suck up mud or sand and digest whatever nutrients are present. Sea cucumbers come in a variety of color1s, ranging from black to reddish-brown to sand-color1 and nearly white. One form even has brilliant purple tentacles . Usually the creature are cucumber-shaped--where their name comes from--and because they live in rocks, this shape, combined with flexibility, enables them to press into crevices where they are safe from animal eater and ocean currents. Although they have greedy desire for food, eating day and night, sea cucumbers have the ability to become still and live at a low metabolic rate--feeding a little or not at all for long periods, so that the living things in the ocean that provide their food have a chance to increase by a large amount. If it were not for this natural ability, they would swallow all the food available in a short time and would probably starve themselves out of existence. But the most impressive thing about the sea cucumber is the way it defends itself. Its major enemies are fish and crabs. When attacked, it forces all its internal organs in its body out into water. It also removes attached structures such as tentacles. The sea cucumber will get rid of its organs and grow itself again if it is attacked or even touched; it will do the same if the surrounding water...???
