Question: Write a multi-choice question for the following article, with the given choices and answer: Article: Empty Deserts In the 19th century Americans from the eastern states moved out west to settle in the rich new lands along the Pacific coast. The most difficult part of their trip was crossing the "Great American Desert in the western part of theprefix = st1 /United Statesby horse and wagon. The western desert can be very dangerous. There is little water and there are few trees. But the desert also has scenery of great beauty. Tall towers of red and yellow stone rise sharply from the flat sandy valley floor. The scene has been photographed many times and appears in movies and in TV. In Arizona, man made dams across the Colorado River have made two large lakes in the middle of the dry desert country. At Lake Powell, the red stone arch of Rainbow Bridge rises high above the blue lake. There are few roads. Many areas ofLakePowell's shore can only be reached by boat or on foot. But hikers in this empty desert land sometimes find very old native American pictures, painted on the rocks. In Death Valley,California, the summer temperature rises to 130 degrees. There is less than two inches of rain each year. Death Valley is the lowest place in America---- 925 meters below sea level. In the 1800s, many travelers died when they tried to cross this waterless valley in the terrible heat. Although the desert is dry and seems empty, there is plenty of life if you look closely. Small insects, snakes and rats have learned how to live in the desert heat. They live under ground and come out at night, when it is cool. Plants such as cacti need very little water. When it does rain in the desert (sometimes only once or twice a year), plants grow quickly, and flowers open in a single day. For a short time, the desert is covered with brilliant color1s.

[Q]: Write a multi-choice question for the following article, with the given choices and answer: Article: Unknown to most Facebook users, the social network actually offers a lot of privacy controls and security features which can help you lock your account, so you can speak freely. If it's used properly, you'll never have to worry about whether you will have to "friend" your boss or your mom. You can friend anyone you want while staying comfortable in the knowledge that not everyone gets to see everything you post. The problem with carrying out these privacy options is that they're just too confusing for most non-tech clever people to handle. And often, most people don't want to bother to take the time to learn. To simplify the process, we're offering one easy step you can take today to help make your Facebook experience safer, more secure, and more private. Just make "Friend Lists". Yes, it will take some time, especially if you're connected to a couple of hundred friends already. But this step, while not the quickest, is fairly simple. And it will be one of the most useful things you can do on Facebook. Friend lists, as the name suggests, are lists for classifying your friends into various groups. The nice thing about this feature is that once you set these lists up, you won't have to do it again. We suggest that you put your work colleagues and professional acquaintances into a friend list named "Work", personal friends you're not very close with into a list called "Acquaintances", and people you're related to into a list called "Family". Those three main categories will separate out the groups of "friends" who you may want to hide some information from. To create a friend list, click on "Friends" at the top of the Facebook homepage. In the left-hand column, click "Friends" again under the "Lists" section. Now you'll see a button at the top that says "Create New List". Click it. In the pop-up that appears, you can name your list and pick members. If you've ever shared an application with your friends, the process of doing this will be very familiar. When you've finished making lists, you'll be able to use... Options: A We can avoid our bosses adding us as friends. B We can share applications with friends. C We can separate acquaintances from family. D We can hide different information from different friends. Answer: D We can hide different information from different friends. Question:

[A]: What advantage can we get from making friend lists?

input: Please answer the following: Write a multi-choice question for the following article, with the given choices and answer: Article: A recently study found people's lives are made shorter in North China. It is showed the life expectancy had been cut down by 5.5 years there. Researchers think that the heavy air pollution in China should be to blame . It's really the truth. Our government has already done something. However, it doesn't seem to work so well. "Air pollution in China is doing harm to people's health. The harm is much more serious than we can imagine," said Chen Yuyu of Beijing University, one of researchers of this study. Dirty air brings serious problems in North China. In January this year, the air pollution was worse than that in other places. That was caused by rising temperature and waste gas from coal heating. Chinese government should strongly fight against air pollution. They should think of more proper ways to deal with the problem. People should be encouraged to take buses, ride bicycles or walk, instead of driving cars. The factories that pollute heavily should be closed. "We need to improve our environment, although it might be expensive. Protecting our environment means protecting ourselves," Li Hongbin, another researcher of the study said.

input: Please answer the following: Write a multi-choice question for the following article, with the given choices and answer: Article: It's not easy being a teenager---nor is it easy being the parent of a teenager. You can make your child feel angry, hurt, or misunderstood by what you say without realizing it yourself. It is important to give your child the space he needs to grow while gently letting him know that you'll still be there for him when he needs you. Expect a lot from your child, just not everything. Except for health and safety problems, such as drug use or careless driving; consider everything else open to discussion. If your child is unwilling to discuss something, don't insist he tell you what's on his mind. The more you insist, the more likely that he'll refuse to talk. Instead, let him attempt to solve things by himself. At the same time, remind him that you're always there for him should he seek advice or help. Show respect for your teenager's privacy . Never read him his mail or listen in on personal conversions. Teach your teenager that the family phone is for the whole family. If your child talks on the family's telephone for too long, tell him he can talk for 15 minutes, but then he must stay off the phone for at least an equal period of time. This not only frees up the line so that other family members can make and receive calls, but teaches your teenager moderation . Or if you are open to the idea, allow your teenager his own phone that he pays for with his own pocket money or a part-time job. Options: A Because the teenager is very naughty. B Because the parent always expects a lot from the child. C Because you can make your child feel hurt, or misunderstood by what you say without realizing it yourself. D Because the teenager wants his or her own space. Answer: C Because you can make your child feel hurt, or misunderstood by what you say without realizing it yourself. Question:
