Problem: Write a multi-choice question for the following article: Article: Have you ever wondered? 1. Why do airplanes take longer to fly west than east? It can take five hours to go west-east from New York (NY) to London but seven hours to travel east-west from London to NY. The reason for the difference is an atmospheric phenomenon known as the jet stream. The jet stream is a very high altitude wind which always blows from the west to the east across the Atlantic. The planes moving at a constant air speed thus go faster in the west-east direction when they are moving with the wind than in the opposite direction. 2. What would happen if the gravity on Earth was suddenly turned off? Supposing we could magically turn off gravity. Would buildings and other structures float away? What happened would depend on how strongly the things were attached to the Earth. The Earth is moving at quite a speed, moving at over a thousand miles per hour. If you turn something around your head on a string , it goes around in a circle until you let go of the string. Then it flies off in a straight line. 'Switching off' gravity would be like letting go of the string. Things not attached to the Earth would fly off in a straight line. People in buildings would suddenly _ upwards at a great speed until they hit the ceiling. Most things outside would fly off into space.

A: Question: What information can we get from the first passage?Options:A It is the jet stream that affects how fast airplanes fly.B Planes go slower when they are moving with the wind.C It takes more time to fly from NY to London than from London to NY.D The jet stream always blows from the east to the west across the Atlantic.Answer:A

Problem: Given the question: Write a multi-choice question for the following article: Article: Some people believe that classes, teachers and school buildings will no longer be necessary in the near future because of the Internet and other new technology. Perhaps this will be true one day, but if the world has no schools, I can't imagine how our society will be. In fact, we should learn how to use new technology to make schools better. We should invent a new kind of school connected to libraries, museums, science centers, labs and even companies. Technological companies should create learning programs for schools. Scientists could give talks through the Internet. TV networks and local stations could develop programs about things students are studying in school. Labs could set up websites to show new technology, so students could see it on the Internet. Is this a dream? No. There have been many cities where this is beginning to happen. Here the whole city is connected to the Internet, and learning can take place at home, at school, and in the office. Businesses provide programs for the schools and the society. The schools provide computer labs for people without their own computers at home. Because everyone can go on the Internet, older people use it as much as younger ones, and everyone can visit faraway libraries and museums as easily as nearby ones. How will this new thing of school change the usual way of learning? It is a little early to be sure, but it is very exciting to think about it. Technology will change the way we learn; schools will change as well; and we will learn something from the Internet.

input question: Write a multi-choice question for the following article: Article: If we are driving a car or crossing a street, we will stop when the traffic lights turn red. Why do we use red rather than other colors? As we know, scattering happens when light goes through the air. For the same media, if the wavelength is long, the scattering will be short. If the wavelength is short, then the scattering will be long. Of all light we can see red has the longest wavelength, so the scattering is the weakest. That means the red light travels far. In fact, it travels farther on rainy days. Using the red light can help drivers in farther areas see the lights. It helps drivers slow down or stop in time. If drivers don't see the red light until they are close, they may not be able to stop the car in time. An accident may happen. Red can also excite people. We can act more quickly when we see the color red. In a word, red light helps drivers stop in time and help prevent accidents.???
output answer:
Question: Red can make people act more quickly because _ .Options:A red can make people happierB the scattering of red is very shortC the scattering of red is very longD red can make people more excitedAnswer:D
