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: Treat with Respect The speed with which Man is changing the face of Earth has outstripped all the mighty processes of nature put together. In his haste to supply himself with increasing quantities of Earth's treasures he risks destroying one he greatly needs, his natural surroundings. Some countries set aside unspoiled areas of natural beauty. prefix = st1 /Canadahas the largest system of national parks in the world, 29 in all covering about 13 million hectares, preserving the different landscapes and the plant and animal life. Other countries are restoring areas which have been reduced to waste land by mining. At Broken Hill in Australiadrifting sand from rock crushing turned the area into a desert swept by sand storms. This is now being irrigated, fertilized and planted with grass and trees. In Great Britain quarries and gravel pits are being filled in or made into lakes, industrial wasteland is being turned into playing fields and waste tips into sloping green hills. However Man tries to look after Earth, the fact is that he is using up at a great rate resources, especially fuel resources, which have taken millions of years to accumulate and which he cannot renew. Yet every day the Earth receives a huge supply of energy from the Sun. Man has made several experiments in using solar energy to heat furnaces , cookers, and water-distillers. In space technology, e.g. on satellites, solar cells convert sunlight into electricity. Houses and offices have been designed which are centrally heated by water or air heated by the sunlight. When Man can trap and store this energy, so that he can use it exactly as he needs it, he will have not only an endless supply, but a clean and safe one.
Answer: Energy from the Sun.

SOLUTION: According to this selected passage, which energy is considered to be endless, clean and safe?

PROBLEM: Article: Science can't explain the power of pets,but many studies have shown that the company of pets can help lower blood pressure and raise chances of recovering from a heart attack,reduce loneliness and spread all-round good cheer. Any owner will tell you how much joy a pet brings.For some.an animal provides more comfort than a husband/wife.A 2002 study by Karen Allen of the State University of New York measured stress 1evels and blood pressure in people-half of them pet owners-while they performed 5 minutes of mental arithmetic or held a hand in ice water.Subjects completed the tasks alone,with a husband/wife,a close friend or with a pet.People with pets did it best.Those tested with their animal friends had smaller change in blood pressure and returned most quickly to baseline heart rates.With pets in the room,people also made fewer math mistakes than when doing in front of other companions.It seems people feel more relaxed around pets,says Allen,who thinks it may be because pets don't judge. A study reported last fall suggests that having a pet dog not only raises your spirits but may also have an effect on your eating habits.Researchers at Northwestern Memorial Hospital spent a year studying 36 fat people and their equally fat dogs on diet-and-exercise programs;a separate group of 56 people without pets were put on a diet program.On average,people lost about 11 pounds,or 5% of their body weight.Their dogs did even better,losing an average of 12 pounds,more than 15%of their body weight.Dog owners didn't lose any more weight than those without dogs but,say researchers,got more exercise overall-mostly with their dogs--and found it worth doing.
Answer: What pets bring to their owners.

SOLUTION: What does the text mainly discuss?

PROBLEM: Article: It was a winter morning,just a couple of weeks before Christmas of 2005. While most people were warming up their cars,Trevor,my husband,had to get up early to ride his bike four kilometers away from home to work. On arrival,he parked his bike outside the back door as he usually does. After putting in 10 hours of labor, he returned to find his bike gone. The bike,a black Kona 18 Speed,was our only transport. Trevor used it to get to work,putting in 60-hour weeks to support his young family. And the bike was also used to get foods, saving us from having to walk along long distances from where we live. I was so sad that someone would steal our bike that I wrote to the newspaper and told them our story. Shortly after that,several people in our area offered to help. One wonderful stranger even bought a bike,then called my husband to pick it up. Once again my husband had a way to get to and from his job. It really is an honor that a complete stranger would go out of their way for someone they have never met before. People say that a smile can be passed from one person to another,but acts of kindness from strangers are even more so. This experience has had a spreading effect in our lives because it made us believe more in the beauty of humanity as a whole. And it has influenced us to be more mindful of ways we,too,can share with others. No matter how big or how small,an act of kindness shows that someone cares. And the results can last forever.
Answer: They used it for work and daily life.

SOLUTION:
Why was the bike so important to the couple?
