The latest craze is sometimes a style of clothes or a hairstyle. Sometimes it is a game or a TV programme. In the 20thcentury a lot of crazes started in the USA and then became popular in the USA andthen became popular in other parts of the world. American youth culture has spread through tourism , TV , films, magazines and music videos. One of the biggest crazes was the hula hoop . Hula hoops are not popular now, but in the1950s they were a _ .  An American company called Wham-O started to make plastic hoops toys, and in the USA the company sold 100 million hoops in a year. Frisbees were another Wham-O product . Some people say that the idea started in the factory of the Frisbee Baking Company in Connecticut. Workers there threw metal pans to each other during their breaks. Two businessmen made a plastic type of the flying pans,  and sold their products to Wham-O. They became a big business. So businesses usually help to produce a craze. Yoyos were another example. In the Philippines,  where its name means "comeback", the yoyo was a popular toy in the 1920s. But it didn't become a global   craze until an American called Donald Duncan bought the idea and sold it to the world. Around 100 million people bought yoyos in 1962 and 1963. Most crazes come and go, but sometimes they survive. When the big skateboard started in California in 1965, many parents and governments said that the boards were dangerous, and they were not allowed in some areas. But the boards became popular again and they are still an important part of youth culture today.???

input question: Write a multi-choice question for the following article: Article: If you were asked what your body is made of, probably you would say that it is made of flesh  and bones and covered with skin. You also know something about the blood which flows through it, and that there is a very important part which we call the brain. But the flesh and the bones make up the largest part of the body, and there is a good deal to be learned about them. You know the general appearance of both flesh and bone from the parts of animals which you see in the butcher's shop. Bone is hard, and of a white color; indeed, it looks more like a piece of wood or stone than a part of a living animal. But bone is a real part of the living body, and it grows and is nourished  just as the body is. If a man breaks the bone of his arm or his leg, it is firmly bound up, to prevent the broken parts from moving out of the proper places, and in time then bone grows together again and becomes quite strong. The bones are fastened together by various kinds of joints . They form the framework of the body, and give it strength to retain its proper shape. This framework is called the skeleton . Some animals, such as worms and slugs, have no skeleton; and others, such as shellfish, have a kind of hard covering or skeleton outside. The most important part of the skeleton is the backbone. It is so important that naturalists divide all animals into two classes,--- those which have a backbone and those which have none. All the higher animals, including man, have a backbone, or vertebral column as it is called. They are therefore called vertebrate  animals. The others are called invertebrate animals.???

input question: Write a multi-choice question for the following article: Article: The earth is 4 600 million years old. We humans have lived on earth for only 35 000 years, but during this period we have changed our planet a lot in many ways. Some things we've done are very good for the earth while some are bad. All over the world, people have cut down millions of trees. When it rains or when the wind blows, the earth is taken away. Forests have become deserts, so more and more sorts of animals and plants are disappearing. In big cities, cars and buses have polluted the air. Many people in cities now have health problems. Factories have also polluted the land and the water. As a result, many rivers and lakes are now dead. Around the earth, there's a special kind of oxygen called "ozone"(O3). It is important to the earth. But now air pollution is destroying it and that has made a very big hole in the ozone layer. Too much harmful radiation from the sun passes through the hole and reaches the earth directly. This is very dangerous because this kind of radiation can cause cancer. Carbon dioxide (CO2) in the air has increased a lot. It mainly comes from burning oil, coal and wood. This has formed a "blanket" around the earth. The heat from the sun can't escape so the temperature is rising. This is called "the greenhouse effect". It causes the level of the oceans to rise and the climate of the earth to change. All these problems are very serious, so we must do something now. ,A, B, C, D.???
