I'm taking a test and have to guess the right answer to the question after the article. Article: The United States economy has dipped into economic recession . This caused discomfort and hardship in every level of society; but for many of the nation's poor, discomfort and hardship turned into misery . An increase in homelessness is probably the worst result of a nation's financial disaster. About 3 million Americans were homeless because of a lack of affordable housing. Experts suggest that a family should spend no more than 30 percent of its income on housing. In fact, in some families housing costs make up 50 percent or more. An unexpected event, such as losing work or illness, can quickly push a family into homelessness. An article in Time magazine tells a story of one such family. A young couple and their three children rented a two-bedroom apartment for about $350 a month. They could hardly go on with the husband's $920-a-month take-home pay; so when their rent was raised to $500 a month, they could no longer make ends meet. Another woman was found dead on a street in Washington D.C., the capital, and she died at a bus-stop across the street from the US Department of Housing and Urban Development. People become homeless for different reasons. Some may not be able to pay for housing, because they have lost their job and cannot find another place they can afford. Others have mental diseases, or are addicted to drugs or alcohol, many of whom do not live with their family. And what's more, there are not enough centers for shelter as the government doesn't pay enough attention to this social problem. People are making efforts to solve the problem. However, it will not be easy, because it is a personal and economical problem as well as a social problem. Question: The passage is mainly about _ in the US. Options: A: ways of solving economic problems B: homeless people being taken good care of C: different reasons for economic recession D: economic recession leading to social problems

I'm taking a test and have to guess the right answer to the question after the article. Article: Is a mouse that can speak acceptable? How about a dog with human hands or feet? Scientists, the people with the know-how to make such things happen, are now thinking about whether such experiments are morally right or not. On Nov. 10, Britain's Academy of Medical Sciences launched a study on the use of animals with human materials in scientific research. The work is expected to take at least a year, but its leaders hope it will lead to guidelines for scientists in Britain and around the world on how far _ can go mixing human genes into animals in search of ways to fight human diseases. "Do these constructs challenge our idea of what it is to be human?" asked Martin Bobrow, a professor of medical genetics at Cambridge University and chair of a 14-member group looking into the issue. "It is important that we consider these questions now so that appropriate boundaries are recognized." Using human material in animals is not new. Scientists have already created monkeys that have a human form of the Huntingdon's gene so they can study how the disease develops; and mice with livers made from human cells are being used to study the effects of new drugs. However, scientists say the technology to put ever greater amounts of human genetic material into animals is spreading quickly around the world --- raising the possibility that some scientists in some places may want to go further than is morally acceptable. Last year in Britain there was a lively debate over new laws allowing the creation of human-animal embryos for experiments. On one side of the debate were religious groups, who claimed that such science interferes with nature. Opposing them were scientists who pointed out that such experiments were vital to research cures for diseases. The experts will publish reports after the end of the study, in which they will give definitions for animal embryos with human genes or cells, look at safety and animal welfare issues, and consider the right legal framework to work within. Question: We can infer from the passage that _ . Options: A: the experts will release reports after the study B: scientists have never doubted the use of animals with human materials C: the creation of human-animal embryos for experiments is legal in Britain D: religious groups hold that cures for diseases have to be done through experiments

Q: I'm taking a test and have to guess the right answer to the question after the article. Article: There are many colors in nature. But do you know if a color has weight? I think you'll say "no". But I am afraid you are wrong. If you don't believe, you may do a small experiment. First, put two objects with the same weight into two boxes. Then cover the box. Third, wrap one box with a red piece of paper, the other with a white piece of paper. OK. Now hold the boxes with your hand one by one. It is certain that you will think the red one is a little heavier. Why do you think so? A scientist found that different colors have different weights in a man's mind. So he did many tests and at last he got the result. That is to say, every color has its own weight in our mind and their order is the same. The heaviest color is red, then blue, green, yellow and white. The scientist told us that colors also have smell. Can you smell the color? Of course not. Then why did the scientist say so? That is because every color stands for a kind of light with a certain wavelength . It reaches our brain through sense organs . According to this discovery, scientists say that people accept the colors they like, and refuse the colors they hate. So your body and mind will be healthy by using the colors you like. Or you'll be nervous or ill. For example, if you stay in a room with red windows, wallpapers and furniture for two hours, you'll feel you have been there for four hours. But if the room is blue, you'll feel you have been there for only an hour. Another example, if a person walks out of a red room and into a blue room, his temperature will fall. That means our body temperature will change with different colors. Question: It can be known from the text that _ . Options: A: colors have order in weight B: colors can change the weight of an object C: people would stay longer in a room with red windows D: colors can affect our mood and health
A: D
*Question*
I'm taking a test and have to guess the right answer to the question after the article. Article: As a young girl, Margaret "Mattie" Knight never played with dolls, preferring to make toys for her brothers instead. In 1849, Knight went to work in a cotton factory where she witnessed a "shuttle," a device that carries thread back and forth across a textile loom , fly off the machine when the thread broke, striking and killing a young boy about her own age. The 12-year-old Knight developed a safety mechanism that made it impossible for a shuttle to leave the loom. The design was so effective, soon virtually every new power loom carried her invention, saving countless workers from injury or death. Being so young, she didn't bother to patent the device, so she never received payment. Knight wouldn't make the same mistake later in life when she invented a machine that could produce flat-bottomed paper bags. Knight had built a small wooden model in her home, but she needed a metal version to show it could hold up to the stress of mass production. So she hired Charles Annan to make the full-sized machine for her, only to have him try to claim the patent for himself. When Knight sued , Annan's argument was that the design had to be his, because no woman could possibly understand the complex mechanics. Knight proved him wrong when she brought back her wooden prototype and explained how every part worked. She won the case in 1871, making her the second woman to hold an American patent. Over a hundred years later, her design is still used as the basis for many modern flat-bottom bag machines. But that wasn't the last the world heard of Mattie Knight. During her lifetime, she made about 90 inventions and received 26 patents, becoming one of the most productive female inventors of the 19th century. Question: What would be the best title for the text? Options: A: Mattie Knight's fight for her patent B: A great woman in the 19 thcentury C: "The female Edison", Mattie Knight D: Great inventions, great woman
