*Question*
I'm taking a test and have to guess the right answer to the question after the article. Article: Mr. Brown first went to look at the underground-fire when he was seven. "Through the hole in the earth you could see the orange fire, but you had to look fast because it was so hot," said Mr. Brown. In 1898,he saw the fire once more. Now, we can only see the smoke. The fire Mr. Brown saw is not the underground-fire. In fact ,there are 260 coal fires in the world. They are harmful and dangerous. Then how to put them out? Scientists have tried to set fire to underground coal to speed up the fires. In this way, the burning of underground coal would be soon finished. Question: What's one of the best ways to put out the underground fire? Options: A: To cover the holes with stones B: To speed the fire C: To see the fire burning D: To do some experiments

I'm taking a test and have to guess the right answer to the question after the article. Article: It might not come as a surprise that China fell behind Western countries in a recent UN report on global happiness. China was only ranked 112th happiest country out of 156 in the UN's World Happiness Report in April. The happiest country, it seems, is Denmark, closely followed by three more northern European countries- Finland, Norway, and the Netherlands. But apart from income and lifestyle differences, there are also cultural reasons for this divide. They show that Chinese people and Westerners have different perceptions of happiness. According to a survey conducted by CCTV, income levels most affected Chinese people's sense of well- being (55.5 percent), followed by health (48.9 percent) and quality of marriage or love life (32 percent). It seems that all these criteria are lagging in China, and that the obvious explanation for greater happiness in the West is higher incomes. But not so, says Professor John Helliwell, an American economist at the University of British Columbia and coauthor of the UN report. According to Helliwell, low-income individuals may experience an initial jump in happiness when their money increases, but this feeling decreases as they adapt to their new circumstances. He stresses the example of the US, where, despite GDP figures rising consistently for the past 50 years, happiness has been steadily declining. This is because people desire more than money and material wealth. "To be happy, we need to feel connection, trust and meaningful relationships," explains Helliwell. Dr Deborah Swallow, a UK expert on cultural diversity however, believes there are some differences in the perceptions of happiness in the West and China. "For North Americans and Europeans, happiness tends to be defined in terms of personal achievement, and is best predicted by self-esteem" she says. "For East Asians, happiness tends to be defined in terms of interpersonal connectedness, and is best predicted by how well involved the self is in a social network." Living standards are not necessarily the last... Question: According to the passage, which of the following about happiness is Correct? Options: A: Happiness has nothing to do with money. B: A man with healthy body must have the most happiness. C: A man who has a strong social relationship is sure to be happy. D: People's sense of happiness is determined by many factors.

I'm taking a test and have to guess the right answer to the question after the article. Article: Inspired by a 9-year-old cyclist who uses only part of one hand, a group of University of Guelph students has won an international award for their invention--a bike brake lever . It pulls both the front brake and the back brake at the same time. Lauren Turner was able to ride her bike, but not as confidently and quickly as her friends. "She couldn't use the front brake. She was only using the back brake, but the front brake makes you stop twice as fast," says Micha Wallace, who with Katie Bell, Anina Sakaguchi and Andrew Morris won second prize in the James Dyson Awards for their single-handed bike braking lever. "She used it all last summer and she had no problems. She said it helped her go faster because she felt more confident in her braking abilities. She felt safer." says Wallace. The invention was the fourth-year design project for the four students. They designed, tested and created a prototype within a four-month period. When Wallace heard about the James Dyson Awards on the news, she and her co-inventors entered their project in the UK-based contest. The contest mainly rewards student designers who create products that improve the way we live. The Guelph students collected the second prize -PS2,000 for them, plus PS500 for their school. As well, they had a chance to meet James Dyson, a UK inventor. While praising the students for their creativity, Dyson said the single-handed lever could improve safety for all cyclists. "By using both brakes at once," he explains, "you could prevent the possibility of flying over the handlebars and ending up with an injury." The students are hoping to sell the patent to a major company. It may be used in other devices that require two hands for operation. Question: The bike brake lever was designed for the purpose of_. Options: A: winning James Dyson Awards B: helping people become confident C: applying for a patent for the invention D: helping the disabled ride their bike safely

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
