Ques: Article: A black hole is a place in space where gravity pulls so much that even light cannot get out. The gravity is so strong because matter has been squeezed into a tiny space. This can happen when a star is dying. Because no light can get out, people can't see black holes. Space telescopes with special tools can help find black holes. The special tools can see how stars that are very close to black holes act differently from other ones. Black holes can be big or small. Scientists think the smallest black holes are as small as just one atom. These black holes are very tiny but have the mass of a large mountain. Mass is the amount of matter, or "staff", in an object. Another kind of black hole is called "stellar" . Its mass can be up to 20 times more than the mass of the sun. There may be many stellar mass black holes in Earth's galaxy. Earth's galaxy is called the Milky Way. The largest black holes are called "supermassive" . These black holes have masses that are more than one million suns together. Scientists have found proof that every large _ contains a supermassive black hole at its center. The supermassive black hole at the center of the Milky Way galaxy has a mass equal to about four million suns and would fit inside a very large ball that could hold a few million Earths. Scientists think the smallest black holes formed when the universe began. Stellar black holes are made when the center of a very big star falls in upon itself, or falls apart. When this happens, it exploded part of the star into space. Scientists think supermassive black holes were made at the same time as the galaxy they are in. A black hole can not be seen because strong gravity pulls all of the light into the middle of the black hole. But scientists can see how the strong gravity affects the stars and gas around the black hole. Scientists can study stars to find out if they are flying around, or orbiting a black hole. When a black hole and a star are close together, high-energy light is made. This kind of light cannot be seen with human... Question: The gravity of a black hole may become so strong that light cannot get out when _ . Yes or no, is the answer "the star is going to die"?
Ans: No

Ques: Article: Everyone wants some degree of success. Many people believe that they deserve success simply because they believe that they deserve success. But there is a widespread belief that people who get on in life may be successful not because they deserve it, but because of influential friends or the right background. Sometimes it may just be a comforting and harmless belief, while at the other extreme it can be very destructive. I once met a brilliant young engineer who worked in a chemical plant. Because of her knowledge and experience, she should have been promoted to Production Manager. Instead, the job went to a man who was totally unsuited for the post. Everyone knew that he only got it because he was politically acceptable to his superiors . This injustice discouraged the young engineer and many of her colleagues. It also meant that the factory was much less efficient than it could have been. At the same time, we should not be pessimistic . More and more the modern world depends on having people who are in the job because they are good enough, not just because their faces fit. There is a story of a factory owner who sent for an engineer to see to a machine which would not go. He examined it, then took out a hammer and tapped, once. The machine started up immediately. When he presented his bill, the owner protested, "This can't be right! $ 100 just for tapping a machine with a hammer?" The engineer wrote out a new bill: "For tapping a machine, $1; for knowing where to tap. $99." Question: What can we learn about the author's attitude toward the widespread belief that "people get on in life may be successful not because they deserve it"? Yes or no, is the answer "He doesn't quite agree with it."?
Ans: Yes

Ques: Article: Everyone wants to know the secrets of a long and healthy life. Here are some discoveries from health experts. Many studies looking into the lives of centenarians look at what they eat. Many people who live into their hundreds live in the Mediterranean , so their diet, which is high in fruits, vegetables, nuts, and healthy fats like olive oil, gets a lot of attention. The diet has been linked to a healthier older age, lower risk for heart disease, and even protection against memory loss. Education is related to a longer life. A 2012 report from the CDC's National Center for Health Statistics found that people with a bachelor's degree or higher live about nine years longer than people who don't graduate high school. James Smith, a health economist at the RAND Corporation, is also a supporter of the argument for staying in school for better life expectancy. His findings show education should be an even bigger factor than race and income. Educated people are more likely to land better jobs, plan for their future, and make healthier lifestyle choices. Being a hard worker doesn't necessarily mean job-stress will harm you. The Longevity Study found that plenty of hard workers lived long lives. "Skeptics may wonder if hard workers really are enjoying life." the authors write, "We found that productive, hardworking people (even in old age) are not stressed or miserable, but tend to be happier, healthier, and more socially connected than their less productive peers." Having a strong social group is associated with a longer life. We often turn to friends and family for support, and taking care of the people that matter to us may help us take better care of ourselves, some evidence shows. Some research even suggests that immune function is improved when we are around our friends, and that they help with stress management. Research shows that sitting for long period of time put people at risk for shorter lifespans and other health risks. A 2011 study found that each hour people spent sitting down and watching TV after... Question: According to the passage, in order to live a long life, we should _ . Yes or no, is the answer "be social and make more friends"?
Ans: No

Ques: Article: Joker found one of the biggest diamonds in the world right in his own back yard. He sold the stone to a diamond dealer for over three hundred thousand dollars. In New York, the diamond was resold---this time for almost eight hundred thousand dollars. The true value of a diamond is never known until it has been cut. Once cut successfully, its value can increase a thousand times. It's easy to understand why the owner of Joker's diamond went to the best diamond cutter he knew, Kaplan. The cutter studied the diamond for twelve whole months. When he felt he was ready to start work, he discovered a flaw . He had to begin his calculations all over again, or he might have made the stone useless. Six months passed, and Kaplan finally said to the owner, "I am ready to start my work. There will be one excellent diamond that will be comparable one excellent diamond of first-class quality " Kaplan waited a few more days until he felt he was in the best physical and mental condition possible. He picked up his tools and held his breath as he made the diamond exactly as he promised. Question: The owner of the diamond thought that if the diamond was cut successfully it might be worth _ . Yes or no, is the answer "$ 800,000,000"?
Ans:
No
