A few days later the man returned and said that his wife liked the pearl so much that she wanted another one just like it. It had to be exactly the same size and quality, because she wanted a pair of earrings made, "Can you give me any advice on how to get such a pearl? " said the man. The jeweler regretfully replied, "I would say it's exactly impossible to find one exactly like that pearl. " The rich man insisted that the jeweler advertise in the newspapers, offering $ 25,000 for the matching pearl. Many people answered the advertisement but nobody had a pearl that was just right. Just when the jeweler had given up hope, a little old lady came into his store. To his great surprise, she pulled the perfect pearl from her purse. "I don't like to part with it," she said sadly, "I inherited it from my mother, and my mother inherited it from hers. But I really need the money. " The jeweler was quick to pay her before she changed her mind. Then he called the rich man's hotel to tell him the good news. The man, however, was nowhere to be found. Question: He paid $ 5,000 for the black pearl without bargaining because _ .

Question: Read the article and select the best answer. Article: The Washington post - NASA's newest space habitat looks sort of like a kids' moon bonce, a big, bright, inflatable globe that could be lots of fun to play in. Soon astronauts on the International Space Station could get the chance to try . The expandable habitat made by Bigelow Aerospace recently passed NASA's strict certification requirements and is scheduled to be flown to the station in September. Called the BEAM ( Bigelow Expandable Activity Module), the habitat would be attached to the space station, where it would stay for two years. While there, it would be tested to see how it handles the _ of space - the radiation, the station's movement and even how it stands up to the debris flying around in orbit. The private Las Vegas company, founded by millionaire real estate mogul Robert Bigelow, won a $17.8 million contract from NASA to provide the module to the space station. "Today is the first step, but it's a big step," said Bigelow's George Zamka. Replace the space station or make it larger. It also hopes to build the habitats on the moon. Its B330 module would be even bigger, with 330 cubic meters of internal ( ) space. The modules could be connected. Creating research facilities, the company says, or even space hotels. In an interview ,NASA's William Gerstenmaier, said he was eager to see how the module performs , and said he was especially pleased " to see how the private sector can step up and help us meet our requirements." The module will be flown to the space station by SpaceX, the first commercial company to resupply the space station. Question: The passage is most probably taken from _ . Options: A: a newspaper B: a booklet C: a magazine D: a science fiction
Answer: A

Question: Read the article and select the best answer. Article: Every vehicle needs tires, but eventually they wear out. Roads wear out too, and they often need repairing. But new research by a pair of teens suggests the rubber from worn-out tires could lengthen the lifetime of asphalt pavement. Also roads made with this material might need fewer patches . The young researchers presented their findings in May, 2014, as finalists at the International Science and Engineering Fair (ISEF). The 64th annual Intel ISEF shows some of the best high school science projects from around the globe. Many roads are made with asphalt, which requires much petroleum. But Jordan is a country that has very few oil wells or other sources of petroleum, notes Mohammad Salameh, who is a 10th-grader at the International School in Amman, Jordan. For Jordan, having to import most of the country's petroleum adds greatly to its cost, the teen notes. The extra expense means that there's less money to build and maintain roads. That has resulted in poorer quality roads. As a result, those roads need to be patched almost constantly. Therefore, 16-year-old Mohammad and his research partner, 15-year-old classmate Adam Belaid, came up with the idea of adding rubber to asphalt. But that rubber can come from old tires. Even a worn-out tire contains much rubber, which means the material should be plentiful, says Mohammad. Drivers in Jordan replaced 9 million tons of tires between 2006 and 2010, and only 0.3% of that rubber was recycled. That leaves much rubber that could possibly go into road construction. But first the teens had to show adding rubber to asphalt resulted in better roads. To test their idea, they created several different asphalt-rubber recipes. They also tried out different temperatures at which the mix was heated. And their tests suggested that when the surfacing material includes 8% rubber, it should hold up for 10 to 15 years of traffic instead of the normal 5 years. And their recipe should reduce the need for patching worn areas from once a year, to maybe once every 5~7 years... Question: We can know from the passage that in Jordan . Options: A: the roads are the worst across the world B: many people are interested in recycling old tires C: a typical road is replaced every five years or so D: most roads require patching once every five years

C
