Q: I'm taking a test and have to guess the right answer to the question after the article. Article: Have you ever felt annoyed when left talking to yourself after your mobile phone battery runs out in the middle of a call? If yes, then here comes some good news. Scientists are now perfecting a way to recharge electrical equipment while on the move. Researchers from theprefix = st1 /Netherlands,FranceandPortugalannounced last week that they have developed very thin solar panels that can be put on clothes. They can also be added to furniture and rooftops. They change light from the sun into electricity. In about three years, you'll be able to wear a jacket that will recharge your phone as you walk. For camping fans, the development could lead to a tent which charges batteries all day so you can have light or music at night. The basic technology of wearable solar panels is the same as that used for traditional solar panels. Pairs of sheets of semi-conducting silicon are linked together to form the panel. But scientists made them much thinner by using different silicon. At one micrometre, they are of the same thickness as photographic film. "This technology will make it easier for people to use clean energy sources," said a physicist in theNetherlandswho led the team of scientists. But the thin panels are not as efficient as the thicker ones. While some solar panels now operate at an efficiency of about 20 per cent, the new flexible panels are only 7 per cent efficient. But the thinner panel is cheaper. An A4 sized panel put onto the back of a jacket cost less than US$13. It could charge a cellphone during a summer walk in the countryside. As long as you stay within range of the transmitting masts that relay a call to the networks, phones will never again run out of power. Question: The passage is written to _ . Options: A: advertise a new product B: explain how a new product works C: introduce a new product D: comepare different ways to use solar energy
A: C

Q: I'm taking a test and have to guess the right answer to the question after the article. Article: Do you know about a series of books that say they are for dummies? These American selfhelp books have been translated into more than thirtynine languages including Chinese, Arabic, Russian, French, German, Greek and Spanish. "Dummy" is a word for a stupid person. The dummy books are not really for stupid people. They are designed to show people how to do something they may never have tried before, like painting a house or learning a language. The books all say in a funny way that they are for dummies, such as WorldHistoryforDummies, RabbitsforDummies, ChineseCookingforDummies, andWeddingPlanningforDummies. The first such book,DOS forDummies, was published in 1991.It helped people learn how to use the DOS operating system for computers. Since then, more than one hundred and fifty million dummy books have been sold. The dummies.comwebsite explains the idea behind the books. It says that they show that people can be taught to do anything. First they can make fun of ideas that are difficult to understand. Then they show how the information can be interesting and easy. he publishers say that the books do not provide more information than necessary. They give readers just enough information to do what they want. They say that the dummy books give the best and easiest way to do something. And the books use simple and easy language. There are more than one thousand different dummy books. A report in NewYorkTimessays that the topselling dummy books are those that explain technology and personal finance. The publishers say that the bestselling dummy books are those providing information many people need--like information about diseases,education and cooking. People interested in opera,car repair and wine can also find dummy books to help them. And there are even more dummy books to come. The publishers say that they publish about two hundred new dummy books every year. Question: Which of the following can be the best title of the passage? Options: A: Books for Dummies B: The Easiest,the Best C: Books for Stupid People D: New Ideas Behind the Books
A: A

Q: I'm taking a test and have to guess the right answer to the question after the article. 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: According to the passage, which of the following is NOT true? Options: A: A black hole can be very tiny but extremely heavy. B: The gravity of a black hole holds all light in its center. C: Scientists observe high-energy light through their own eyes. D: Some small black holes came into being as early as the universe.
A: C
