TASK DEFINITION: In this task, you're given an article and an answer. Your task is to generate the question for the answer based on the given article.
PROBLEM: Article: A father wanted to buy a horse for his son. After looking at many horses, the man's decision was almost made. It had come down to a choice between two horses. They were quite similar and the prices were the same. He decided to take another look so he could make a final decision. The first farmer was eagerly trying to sell his horse and talked much about how cute his horse was, but the father didn't reach a decision. The second farmer was different. He didn't say anything about the horse, but he simply said that he was sure the man's son would love his horse. He offered to bring the man a saddle , a bridle , the horse and enough food for it for 30 days. In return , the father should give him a check, and he would hold it for 30 days. If the man's son decided to keep the horse, he could let him know at the end of the 30 days, and he would cash the check. Otherwise, he would give back the man's check, pick up the horse and even clean up where the horse had been to. Which farmer do you think sold his horse? Can you see that if you promise buyers reliable business dealings with you, you are more likely to be successful? The farmer gave more far beyond what the father thought or even imagined.
Answer: The two horses were quite similar.

SOLUTION: Why was it hard for the father to make a decision at first?

PROBLEM: Article: A recent study, while showing a generally positive attitude toward science, also suggests a widespread worry that it may be "running out of control". This idea is dangerous. Science can be a force for evil as well as for good. Its applications can be channeled either way, depending on our decisions. The decisions we make, personally or collectively, will determine the outcomes of science. But here is a real danger. Science is advancing so fast is so strongly influenced by businesses that we are likely to believe whatever decisions we come to will make little difference. And, rather than fighting for the best possible policies, we may step back and do nothing. Some people go even further. They say that despite the moral and legal objections , whatever is scientifically possible will be done ----somewhere, sometime. They believe that science will get out of control in the end. This belief is dangerous too, because it a fuels sense of hopelessness and discourages them from making efforts to build a safer world. In our interconnected world, the lack of agreement in and of the world of science can lead to the failure to control the use of science. Without a common understanding, the challenges of "controlling" science in this century will be really tough. Take human cloning for example. Despite the general agreement among scientists on its possible huge impact on traditional moral values, some countries still go ahead with the research and development of its related techniques. The outcomes are hard to predict. Therefore, discussions on how science is applied should be extended far beyond scientific societies. Only through the united efforts of people with hope, can we be fully safe against the misuse of science and can science best serve mankind in the future.
Answer: People hold mixed opinions about science.

SOLUTION: What can we conclude from the recent study?

PROBLEM: Article: Using too much water or throwing rubbish into our rivers are clear ways that humans can put our water supply in danger , but we also affect our water supply in less obvious ways. You may wonder how paving a road can lead to less useable fresh water. A major part of the water we use every day is groundwater. Groundwater does not come from lakes or rivers. It comes from underground. The more roads and parking lots we pave the less water can flow into the ground to become groundwater. Human activity is not responsible for all water shortages . Drier climates are of course more likely to have droughts than areas with more rainfall, but in any case, good management can help to make sure there is enough water to meet our basic needs. Thinking about the way we use water every day can make a big difference, too In the United States , a family of four can use 1. 5 tons of water a day! This shows how much we depend on water to live, but there's a lot we can do to lower the number. You can take steps to save water in your home. To start with use the same glass for your drinking water all day. Wash it only once a day. Run your dishwasher only when it is full . Help your parents fix any leaks in your home. You can even help to keep our water supply clean by recycling batteries instead of throwing them away.
Answer: Throwing rubbish into lakes.

SOLUTION:
Which of the following is most likely to lead to less groundwater?
