Ques: I'm taking a test and have to guess the right answer to the question after the article. Article: It's illegal for the police to attach a GPS unit to your car without your permission, as the U.S. Supreme Court settled in 2012.But if the police are in hot pursuit of a bank robber or other escaping criminals that threaten public safety, a GPS tracker is acceptable. But exactly how can the police GPS track a car that is moving fast? The answer to that question comes from StarChase,a new police technology being used by a small but growing number of law enforcement agencies.It allows the police to fire 4.5-inch glue-covered GPS bullet-like projectiles from an air gun fixed in their police cars.If the GPS tracker makes contact with the escaping robber's car, it'll stick no matter how fast the vehicle is going.That way, the police will have a constant read on the car's location and heading.Aside from simply apprehending criminals,it's believed this new technology could help save lives.If the police successfully fire a GPS unit at a speeding criminal,they can pull back from a high-risk chase.Chases can be incredibly dangerous to all involved,including innocent bystanders and other drivers.Once the GPS bullet connects,there's no need for the chase any longer. Now,predictably,a GPS-loaded gun isn't cheap. Police departments need to pay about $5.000 per vehicle for the technology,and individual GPS bullets cost as much as $250 each.That may sound expensive,but remember:The alternative is often thousands of dollars in property damage,and great human cost in injury and lost life.According to Star Chase,their GPS bullet system has an apprehension rate of 80%without any report of inury or property damage.If you'd like to learn more about the StarChase system,Popular Mechanics has just published a good article about it.There's also plenty more information available at the company's website. Question: When the GPS bullet sticks to the escaping robber's car,the police can _ Options: A: know the car's condition B: ensure the robber's safety C: play a fair game with the robber D: know the car's position and direction
Ans: D

Ques: I'm taking a test and have to guess the right answer to the question after the article. Article: George Gershwin, born in 1998, was one of America's greatest composers. He published his first song when he was eighteen years old. During the next twenty years he wrote more than five hundred songs. Many of Gershwin's songs were first written for musical plays performed in theatres in New York City. These plays were a popular form of entertainment in the 1920s and 1930s. Many of his songs have remained popular as ever. Over the years they have been sung and played in every possible way -- from jazz to country. In the 1920s there was a debate in the United States about jazz music. Could jazz, some people asked, be considered serious music? In 1924 jazz musician and orchestra leader Paul Whiteman decided to organize a special concert to show that jazz was serious music. Gershwin agreed to compose something for the concert before he realized he had just a few weeks to do it. And in that short time, he composed a piece for piano and orchestra which he called Rhapsody in Blue. Gershwin himself played the piano at the concert. The audience were thrilled when they heard his music. It made him world-famous and showed that jazz music could be both serious and popular. In 1928, Gershwin went to Paris. He applied to study composition with the well-known musician Nadia Boulanger, but she rejected him. She was afraid that classical study would ruin his jazz-influenced style. While there, Gershwin wrote An American in Paris. When it was first performed, critics were divided over the music. Some called it happy and full of life, to others it was silly and boring. But it quickly became popular in Europe and the United States. It still remains one of his most famous works. George Gershwin died in 1937, just days after doctors learned he had brain cancer. He was only thirty-nine years old. Newspapers all over the world reported his death on their front pages. People mourned the loss of the man and all the music he might have still written. Question: Which of the following best describes Gershwin? Options: A: Talented and productive B: Serious and boring C: popular and unhappy D: Friendly and honest
Ans: A
