I'm taking a test and have to guess the right answer to the question after the article. Article: Turning the lights out or wearing a blindfold while eating could be a quick way to lose weight, according to scientists. The simple trick works because it stops diners eating for pleasure rather than for calories. It also triggers a part of the brain that is worried that unseen food may go bad. An experiment by the University of Konstanz, in Germany, found that people who were blindfolded consumed nine percent fewer calories before they felt full, compared to those who could see. They also vastly overestimated how much they had eaten because they could not see how much was left on the plate. Blindfolded volunteers estimated they had eaten 88 percent more than they actually had. Scientists believe that not seeing food on the table also allows the body to know when it is full in real time rather than remembering past experiences where it might have taken a full plate to feel full. In the experiment, 50 people were blindfolded and 40 were allowed to see their food. All were told not to eat within two hours of the experiment. They were then given three 95g bowls of chocolate ice cream and invited to eat for 15 minutes. Their bowls were taken away and the remaining ice-cream weighed, while the participants were quizzed on how much they thought they had eaten. On average the group who could see ate 116g while the blindfolded groups ate 105g. However, the blindfolded group believed they had eaten 197g while compared with 159g for the non-blind volunteers. They were also asked how pleasant the ice-cream tasted and the blindfolded group rated lower than those who could see. "The experienced pleasure of eating was significantly lower in the blindfolded group. Not seeing the food might have decreased the appetite. Sight plays an important role in the eating experience and in the overall dining experience." Previous studies have shown that the visual influence of food plays a large part in the taste. While restaurants that allow diners to eat in the dark state that it triggers other senses, in fact eating in darkness... Question: The main purpose of the passage is to _ . Options: A: provide statistics related to eating in the dark B: offer reasons for people to eat in the dark areas C: inform the readers of the result of an experiment D: persuade the readers to lose weight in a new way

I'm taking a test and have to guess the right answer to the question after the article. Article: Electronic books have changed the way many people read for pleasure. Now online textbooks are changing the way some students learn and some teachers teach. More than one hundred seventy-five thousand students attend the public schools in Fairfax County, Virginia, outside Washington. Last year, the school system used digital books in fifteen schools. This school year, middle schools and high schools changed from printed to electronic textbooks in their social studies classes. Luke Rosa is a history teacher at Falls Church High School. His students work on laptop computers at school. He explains the idea to them this way. "I mean, it's just like a regular textbook, except it's got it all online." Peter Noonan, an assistant superintendent of schools, said, "The world's changing. And the online textbooks can change right along with the events that are happening." Digital books also cost less than printed textbooks, he said. A student named Melanie Reuter said, "I don't have to carry a textbook around, so that's nice." But another student said, "I don't like it because the Internet sometimes doesn't work." Students also need access to the Internet when they are not at school. About ten percent of students in Fairfax Country do not have a computer or online access at home. Public libraries in the country have free Internet. There are also after-school computer labs as well as computer clubhouse supported by the country. Middle school student Slieman Hakim is happy about that. He said, "My family only has one computer; my sister and I both do our homework on it. So I come here to do my homework. It's good." Other school systems in the area are also considering online textbooks. Question: Which of the following is /are NOT used when students have social studies classes? Options: A: Paper textbooks. B: The Internet. C: Computers. D: Electronic textbooks.

Q: I'm taking a test and have to guess the right answer to the question after the article. Article: The UN Security Council was created in 1945. It is made up of 10 rotating members and five permanent members, which have a veto, the power to stop a resolution . Most UN members now consider the organization's structure outdated. But any changes need the agreement of two-thirds of the 191 members, and no veto from any of the five permanent council members. Last year, Japan, Germany, Brazil and India formed a lobbying group to get permanent council seats. But North and South Korea have doubts about Japan, Italy opposes Germany for a seat, Pakistan is against India's candidacy and Mexico and Argentina Brazil. A wave of emotion swept through China last week as millions voiced their opposition to Japan's permanent membership of the United Nations (UN) Security Council. By last Friday over 22 million Chinese had signed an online petition against Japan's bid for a permanent seat on the council. According to major Chinese websites, such as sina.com, more than 170,000 overseas Chinese also signed. This is the first online activity of its kind. The petition was started by US-based Alliance for Preserving the Truth of the Sino-Japanese War . They want Japan to apologize for crimes during World War II. The group also plans to present the petition to the UN this autumn. Chinese Foreign Ministry spokesman Liu Jianchao said he didn't think the petition shows anti-Japanese feeling. He believed instead it is a request for Japan to take a responsible attitude towards history. Question: What's the main reason for China's opposition to Japan's permanent membership of the Council? Options: A: Japan is unwilling to admit to its crimes against the Chinese in the World War II. B: Millions of people in Asia signed a petition against it. C: The Chinese people have strong anti-Japanese feeling. D: Japan is an irresponsible country that once had a history of invasion.

I'm taking a test and have to guess the right answer to the question after the article. Article: It's true that many dads in the wild aren't interested in parenting, but there are some that work pretty hard to give their little ones a good start. Maybe one of these dads will make you remember your own dad! The male giant water bug doesn't seem to mind a heavy load on his back for his kids. The female puts about 100 to 150 eggs on the back of the male, and then she leaves. Once the female is gone, the male has to look after the eggs. It usually takes one to two weeks for the eggs to hatch. The father giant water bug jumps around to make sure the growing eggs get enough air and water. All this time he can't fly because of the weight of the eggs growing rapidly on his back. Now let's turn to the male stickleback fish. When the mother leaves after laying her eggs, the father tends his young. If the young fish go too far away, their father helps with their safe return by carrying them back in his mouth. The male stickleback looks after all his young -- as many as 100 -- until they can live on their own. A similar example can be found in emperor penguins living in cold areas. The male emperor penguin goes without food while looking after his egg until it hatches. For about 62 to 67 days, the egg stays on top of the father's feet, in very cold temperatures that drop down to -39deg C. As a result, the father may lose nearly 50 percent of his body weight while waiting for his baby penguin to be born! Question: What do we know about the giant water bug? Options: A: It is unable to fly. B: The eggs grow on the father's back. C: The male must keep still to hatch the eggs. D: The female looks after her eggs together with the male.
