Problem: Given the question: Write a multi-choice question for the following article: Article: Entire populations of American toads breed within the same few days at the same time each year, usually late April or early May. The toads hop to their breeding ponds after the ground has warmed and the first hard spring rain falls. To get there, many of the toads will cross roads that cut through their habitat. It will be a grand view of hopping toads as well as a disastrous killing by cars! The toads are "slow in moving at that time of year--it's still cool, they've been inactive--and they get killed" by cars when crossing roads, said Serrao, a naturalist. An April night five years ago, when Serrao went out to a country road to watch the moving of the toads, he counted 100 toads; 95 were hit by cars. A similar story can be told for several other species of toads, frogs, crocodiles and turtles around the world. The world's amphibians are reducing, and road-killing is just one factor behind it. Other better-known causes of the decline include global warming, insecticides , and the loss of wetlands. Serrao says unless these animals get help crossing the road, their local populations will disappear. Jackson, a biologist, said one way to help amphibians survive road crossings is to construct "amphibian tunnels" beneath the road. Jackson says tunnels should be a 0.6-meter-by-0.6-meter box, open at the top, and fitted with an iron grate to allow enough air and light into the tunnel. In addition, fences or walls should extend out from either side of a tunnel for about 30 meters, which guide amphibians toward the tunnels. European countries have built amphibian tunnels for decades. Jackson led a team that installed the first such tunnel in prefix = st1 /Americain 1987, which helped over 3/4 of the local amphibian population safely cross the road. Jackson says that there are about a hundred amphibian tunnels in the UStoday, but many of them were not carefully designed and probably not working well because land developers wanted to save money.

Problem: Given the question: Write a multi-choice question for the following article: Article: Besides giving off gases and dusts into the air, humans produce waste that is poured on the environment. Often, this waste produced by major industries and people is harmful to both nature and human life. One of the main causes of the large amount of dangerous waste is that people do not realize how large a problem it is. Because it can be simply removed and sent to a landfill ,the problem is often believed to end there. In addition, industries have often shown an unwillingness to find ways to deal with dangerous waste because of the related expenses. Many industries and governments build simple landfills to store waste, and often just pour waste chemicals into nearby bodies of water. Often, chemicals used for industrial production cause dangerous forms of waste.The amount of these chemicals has increased greatly in the past, but it is often difficult and expensive to get rid of these chemicals or to store them in a way safe to human life and the environment. Every year, major health problems result from dangerous waste. Sadly, it is often only after someone has died or become seriously ill that governments will take measures to reduce levels of harmful waste. Some governments have realized how serious the dangerous waste problem is and are now trying to settle this problem. They are also trying to limit the amount of waste industries are allowed to produce. Not only governments but ordinary people as well must work together to solve the problem. They can choose not to buy those products which require the production of dangerous waste, and produce less harmful waste themselves. Many scientists think that waste production can be cut. The waste can be reduced by at least one third using existing technologies and methods.

The answer is:
Question: What troubles industries most in dealing with the dangerous waste problem?Options:A How to get government support.B How to increase their production.C How to store harmful waste.D How to cut down the related costs.Answer:D

Problem: Given the question: Write a multi-choice question for the following article: Article: One day in Australia I decided to try hang gliding . I went up with an instructor, floated and flew above the waves for about 20 minutes, then landed on the sand. His wife was there to meet us so she could drive us back. Their son, about 8 years old, was with her. As the four of us were standing there a woman named Sue came up with a big smile. She gave a warm hello to the couple, and then asked the boy, "How's school, mate ?"With a troubled look on his young face, the boy quietly said, "Not good." In response Sue exclaimed ,sounding surprised , "Not good ?I bet it is fun." Then she turned her attention back to the boy's parents. They started talking about some of their friends, smiling and laughing . Meanwhile, all three of them completely ignored the boy . But I watched his head drop.I watched him turn away from the group, take a few steps ,and just stand there ,alone. I still find it hard to believe that anyone could miss a child's reaction that completely. I wondered how the three adults could stand there and laugh while that boy stood there alone, troubled not only about school but also that no one was interested in his troubles. Maybe his father tried to distract his son with risky sports. As long as you are active, you can't feel your emotional pain. But what if his son is not interested in sports? These were what most people would say are "good parents" . But I say that what they did was child abuse. It was total emotional neglect at that moment . And that is why I am writing this story. To remind everyone that it is little interactions with children that make a difference in their lives and in society.
