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.

Example Input: Article: As a young girl, Margaret "Mattie" Knight never played with dolls, preferring to make toys for her brothers instead. In 1849, Knight went to work in a cotton factory where she witnessed a "shuttle," a device that carries thread back and forth across a textile loom , fly off the machine when the thread broke, striking and killing a young boy about her own age. The 12-year-old Knight developed a safety mechanism that made it impossible for a shuttle to leave the loom. The design was so effective, soon virtually every new power loom carried her invention, saving countless workers from injury or death. Being so young, she didn't bother to patent the device, so she never received payment. Knight wouldn't make the same mistake later in life when she invented a machine that could produce flat-bottomed paper bags. Knight had built a small wooden model in her home, but she needed a metal version to show it could hold up to the stress of mass production. So she hired Charles Annan to make the full-sized machine for her, only to have him try to claim the patent for himself. When Knight sued , Annan's argument was that the design had to be his, because no woman could possibly understand the complex mechanics. Knight proved him wrong when she brought back her wooden prototype and explained how every part worked. She won the case in 1871, making her the second woman to hold an American patent. Over a hundred years later, her design is still used as the basis for many modern flat-bottom bag machines. But that wasn't the last the world heard of Mattie Knight. During her lifetime, she made about 90 inventions and received 26 patents, becoming one of the most productive female inventors of the 19th century.
Answer: It reduced injuries at textile plants.
Example Output: What do we know about Knight's first invention?

Example Input: Article: My 11-year-old son and I rides bikes to and from his school every day. I accompany him on the 20-minute ride through Manhattan, drop him off and return at the end of day to pick him up. We always ride together; sometimes he leads; sometimes I do. And as we ride, we communicate the ways to minimize the dangers: Don't go too fast, and watch out for doors suddenly swinging out from parked cars and jaywalking pedestrians, etc. Some friends worry about the risk of riding in traffic, but is there a better way to let my son know how to deal with traffic dangers? But recently he requested me to start hanging back a half block or so. This way he could enjoy the feeling of riding on his own, with the security of knowing that I was nearby in case he needed me. This is healthy, of course, as my son needs space to develop independence in preparation for his inevitable (,) departure from home. However, that means soon he will want to ride to school on his own, and I will no longer have this wonderful routine. "Let your children go if you want to keep them." I understand this and am trying to let my son go in age-appropriate phases, but I still suffer. It's one of the most troubling experiences of parenthood -- recognizing that your presence is becoming less welcome. My dilemma as a husband mirrors the concern I feel as a parent. My wife has just left on a six-month mission to cover the situation in Libya. In the days leading up to her departure, we spoke openly about the possibility, however unlikely, that she might be killed. But while I influence her decisions, I do not control them. Finally, it was her decision. I know that letting go is the wisest path in this case too. As we travel through life's phases, we must let go of so much. And I don't think it gets easier with practice. But maybe just accepting that eventually we will have to let go is the secret to living a full life.
Answer: To teach his son to ride in traffic.
Example Output: Why does the writer accompany his son on his daily ride to school?

Example Input: Article: A victim of climate change A polar bear's dead body found on the Arctic island of Svalbard, the northernmost part of Norway, has shocked experts who say climate change may be to blame for the death. The starved polar bear in Norway was said to be in good bones by the time a group of explorers came across its body in July. The bear is thought to have been heading north in a desperate search for sea ice that would allow it to hunt for seals."From his lying position in death, the bear appears to simply have starved to health in April when the Norwegian Polar Institute examined and labeled it. However, the animal was reduced to skin and bones and died where he dropped," polar bear expert Dr. Ian Stirling, a professor at the University of Alberta said, "He had external suggestion of any remaining fat, having been reduced to little more than skin and bone." Stirling believes the bear starved to death as a result of a lack of sea ice which the animals use as a platform for hunting seals. That may also explain why the 16-year-old male bear was found about 155 miles north of where it was seen in April. Arctic sea ice reached a record low in 2012, according to a report released this week by the National Oceanic and Atmospheric Administration that pointed to continued signs of climate change. The International Union for Conservation of Nature currently classifies polar bears as _ e on its Red List of Threatened Species.
Answer: By his lying position in death.
Example Output:
How did Stirling know the reason for the death of the polar bear?
