Q: I'm taking a test and have to guess the right answer to the question after the article. Article: In jokes, the chicken only crosses the road. In Australia,cane toads use roads to travel. A new study finds that Cane toads are using roads to spread across the continent. They take shelter overnight close to the opencorridors , and then hit the road each evening in their damaging way. Cane toads were brought into Australia from Hawaii in 1935 to control the spread ofbeetles that were destroying Australia's sugar cane crop. _ are now moving into new places at the speed of 30 miles a year. Toads can grow as large as dinner plates and can weigh up to 4.5 pounds. Their heads and backsides are covered with rows ofwarts . They are known to kill snakes, lizards and other animals, including pet dogs. They have no natural enemy in Australia. According to a research, toads make slower progress through thick plants than along open spaces and they hop alongside roads and fences whenever possible. Toads use long corridors that are well-suited for them to travel long distances. Another study recently found that toads haveevolved longer legs in recent years and that this is also helping them in their spread. Efforts to kill toads have been largely unsuccessful, although scientists tried their best. Another new finding suggests ways to slow down its population. For example, roadside borders can be changed to make them less attractive to toads, or allowing thick plants to grow along the sides of highways, thus forcing toads onto the road of themselves. Question: According to the passage, the ways to slow down the population of toads are based on the fact that cane toads _ . Options: A: move slower through thick plants B: have no natural enemy in Australia C: mainly live near the roadside D: like traveling at night
A: A

Q: I'm taking a test and have to guess the right answer to the question after the article. Article: Whenever we see a button, we are eager to press it because we know something will happen. This is true in most cases, for example on a doorbell and on the "on/off" button on the TV. But some buttons are actually fake, like the "close" button on a lift. Many people are in the habit of pressing the "close" button because they don't have the patience to wait for the lift doors to shut. But lifts' "close" buttons are a complete scam , at least in the US-the doors will not close any faster no matter how hard you press. It started in the 1990s when the Americans with Disabilities Act was passed in the US, making sure that all lifts stayed open long enough so that people with disabilities could enter. Only US firefighters and repairmen can use the buttons to speed up the door-closing process if they have a code or special keys. But to normal lift riders, the buttons aren't completely useless. According to psychologists, fake buttons can actually make you feel better by offering you a sense of control. "Perceived control is very important. It reduces stress and increases well-being," Ellen J. Langer, a psychology professor, said, " having a lack of control is associated with depression." Experts have revealed that a lot of buttons that don't do anything exist in our lives _ . For example, many offices in the US have fake thermostats because people tend to feel better when they think they can control the temperature in their workspace. But psychologists found it interesting that even when people are aware of these little "white lies", they still continue to push fake buttons because as long as the doors eventually close, it is considered to be worth the effort. "That habit is here to stay," John Kounios, a psychology professor, said. "Even though I have real doubts about the traffic light buttons, I always press them. After all, I've got nothing else to do while waiting. So why not press the button in the hope that this one will work?" Question: According to John Kounios, people who press fake buttons _ . Options: A: should give up this habit B: probably do so to kill time C: consider what they do to be meaningless D: don't know that what they press is fake
A: B

Q: I'm taking a test and have to guess the right answer to the question after the article. Article: Today, over six billion people live on the planet. This means that there are very few places on Earth with no people. One place that has very few people is at the bottom of the Earth. In Antarctica, the icy continent surrounding the South Pole, you will not find anyone who lives there all the time. First, Antarctica is the coldest place on Earth. For example, it can be -l30degC in the winter. Humans cannot live in this kind of environment. Because it is so cold, very few plants or animals live there. This means there are no farms and no places to find wild plants or animals to eat. Second, Antarctica can be dangerous. Many people think that it is safe to travel to Antarctica in the summer months when it is warmer. However, Antarctica is mostly ice, so when it's summer, the ice melts. When the ice melts, the ice can break. So, people cannot travel around Antarctica during the summer. If the ice breaks, they could fall into the water and die. Another serious problem in Antarctica is the sun. Because Antarctica is mostly ice, there are no trees so there is no shade. Also, the ground is mostly white ice so the sun bounces off it. The light from the sky and the light from the ground can burn people's skin and hurt their eyes. People must be very careful in this situation. For example, they must wear sunglasses to protect their eyes. They must also cover their hands and faces all the time. Although Antarctica is a tough place to live, explorers have discovered coal in Antarctica. This leads them to believe that Antarctica at one time was a land of swam and forests. Question: When is the most dangerous time to travel around Antarctica? Options: A: In spring. B: In summer. C: In autumn. D: In winter.
A: B
