Article: On July 1 at exactly 7:59:59, Bejing time, the world' s atomic clocks will pause for a single second, or, more precisely, change to the unusual time of 7:59:60. The addition of a leap second , is to keep our clocks in time with the slowing of Earth' s rotation and astronomical time as measured by the sun. Just one extra second could affect the way computers and websites work, however. When the last leap second was added back in 2012, the community website Reddit crashed. For Reddit, the problem was that a Linux system got confused when it checked the network time and found an extra second. Speaking to Wired about the problem back in 2012, Linux creator Linus Torvalds commented:"Almost every time we have a leap second, we find something. It' s really annoying, because it' s code that is almost never used, and thus not tested by users under their normal conditions. " Companies have thought of their own solutions, and Google' s"leap smear"may be the best- known example. As company engineer Christopher Pascoe explains in a blog post, companies usually try to turn back the clocks by one second at the end of the day so that they play that second again. However, Pascoe believes this creates problems. He asked:"Does email that comes in during that second get stored correctly?"Google has a solution: Cut the extra second into milliseconds and then put these tiny amounts of time into the system throughout the day."This means that when it became time to add an extra second at midnight."Says Pascoe."Our clocks have already taken this into account over the course of the day." For many companies without Google' s money, however, the leap second will likely still cause some crashes. Question: How do companies usually deal with the problem of the extra second? Yes or no, is the answer "By turning the clocks back by one second at the end of the day."?
No

Article: If you look outside, you probably will see some kind of insect. If your first instinct is to kill it, take a moment to think about all of the benefits insects provide to the environment. Entomologists, scientists who study insects, estimate that there are more than 800,000 species of insects found throughout the world. Only a few hundred of these insects are considered harmful. Mosquitoes, for example, are considered harmful. They bite humans and other animals, and their bites can cause skin pain and spread disease. Desert locusts also are considered harmful because they destroy crops causing billions of dollars in damage each year. However, the number of helpful insect species far outweighs the number of harmful species. Some insects make up a vital part of the food chain. Many different birds, reptiles, fish and even plants eat insects. There are also about 500 insects that people in various parts of the world eat. These insects are considered delicious food and prized for their high protein, mineral, and vitamin content. Other insects produce valuable commercial products such as silk, wax, and honey. Of all the insects, perhaps the most important are those that travel from flower to flower and pollinate the plants they visit. Agriculture around the world would be very different without the bees, butterflies, moths, flies and wasps that pollinate many crops. In fact, nearly one-third of the food you eat depends on plants that are pollinated by insects! While it is true that some species of insects harm or annoy us, _ . You may be destroying one of the hundreds of thousands of insects that provides many benefits to human beings. Question: According to the passage, the most important type of insects are _ . Yes or no, is the answer "insects that travel around and pollinate plants"?
No

Q: Article: Alan Tong was the worst driver in town. He had an accident of some kind almost every week. Alan lived with his mother. His mother was always worried about him. Every day she worried that police would turn up to arrest him. This wasn't a foolish worry because they usually called on the Tong household about once a week to deliver a speeding ticket or to serve him notice to appear in court. Most of his accidents were caused by his carelessness. He drove through red lights. He turned right without signaling. He drove at night without proper lights. He overtook other cars on hills and sharp curve. In short there wasn't a traffic regulation Alan had not broken, and he had had so many accidents that it was a miracle he was still alive. But luckily for Alan, he had never hurt anyone in his accidents or even gone to the hospital. Although Alan wasn't popular with the police, he was very popular with his lawyer. Alan's lawyer, Mr.Tsui, had earned a lot of money from Alan's cases and always rubbed his hands expectantly when he saw Alan coming into his office. One day Alan was working in the garage spraying painting his car when his mother walked in. "What are you doing?" his mother asked. "Painting my car," Alan replied. "I can see that," his mother said, "but why are you painting one side of the car red and the other side blue?" "Because every time I have to go to court for a traffic offense, there are always two witnesses . "What color1 was the car?" the prosecutor always asks, and the two witnesses always give the same answer. Well, in the future, one witness will say it was blue. Mr. Tsui will then say to the judge, "Your honor, the witnesses cannot even agree on the color1 of the car involved in the accident." And the judge will have to dismiss the case against me. Question: Why was he doing this? Yes or no, is the answer "To confuse the evidence against him."?
A: No
