In this task, you're given an article and an answer. Your task is to generate the fill-in-the-blank question for this answer based on the given article. The blanks are always at the end of the question, and can be filled with more than one word or phrase.

Example Input: Article: It was the summer of 1965. Deluca, then 17, visited Peter Buck, a family friend. Buck asked Deluca about his plan for the future. "I'm going to college, but I need a way to pay for it," Deluca recalls saying. "Buck said, 'you should open a sandwich shop.'" That afternoon, they agreed to be partners. And they set a goal: to open 32 stores in ten years. After doing some research, Buck wrote a check for $1,000. Deluca rented a storefront in Connecticut, and when they couldn't cover their startup costs, Buck kicked in another $1,000. But business didn't go smoothly as they expected. Deluca says, "After six months, we were doing poorly, but we didn't know how badly, because we didn't have any financial controls." All he and Buck knew was that their sales were lower than their costs. Deluca was managing the store and to the University of Bridgeport at the same time. Buck was working at his day job as a nuclear physicist in New York. They'd meet Monday evenings and brainstorm ideas for keeping the business running. "We convinced ourselves to open a second store. We figured we could tell the public, 'We are so successful; we are opening a second store.'" And they did--in the spring of 1966. Still, it was a lot of learning by trial and error. But the partners' learnasyougo approach turned out to be their greatest strength. Every Friday, Deluca would drive around and handdeliver the checks to pay their supplies. "It probably took me two and a half hours and it wasn't necessary but as a result, the suppliers got to know me very well, and the personal relationships established really helped out," Deluca says. And having a goal was also important. "There are so many problems that can get you down. You just have to keep working toward your goal," Deluca adds. Deluca ended up founding Subways Sandwich, the multimilliondollar restaurant chain.
Answer: pay for his college education
Example Output: Deluca opened the first sandwich shop in order to _ .

Example Input: Article: Humans are well-equipped for life on Earth. But in space, it is different. Low or _ changes how the blood flows and causes motion sickness, muscle loss and tiredness. Weightlessness can also cause bone loss. But scientists are experimenting with little worms to better understand how space travel affects astronauts. The millimeter-long worm is called C. elegans. The see-through worm is often used in medical studies because its life is only about two weeks long. Seventy percent of its DNA is the same as human DNA. Sabanayagam is a scientist, who built a micro-gravity simulator to test how C. elegans would perform in the actual zero gravity of space. Scientists put the worms into the simiulator full of water. After a week they take out the worms. They look for changes in the worms' epigenome,which are chemical markers that tell the DNA in the cells how to perform. The epigenome can be changed by the environment. And those changes pass from one generation of worms to the next. "When the worms are in a liquid environment, some epigenomic marks remain even when we take the animal out of the liquid environment and put it back into normal ground conditions. So its offspring keeps this epigenomic memory of the parents' liquid environment or microgravity environment." The information the scientists have gathered suggests that the epigenomic marks appear during the early part of a worm's life. Mr. Sabanayagam says he thinks scientists can find genes in the human similar to those in the worms that responded to microgravity and scientists could possibly observe those genes closely when astronauts travel in space. Sabanayagam expects C. elegans to visit the International Space Station within two years. He says he hopes information gathered from the worm studies can be used to develop simple, low-cost and quick tests to measure an astronaut's health.
Answer: has a short life period
Example Output: From the passage we can know C. elegans _ .

Example Input: Article: Though war is something people hate, Director Feng Xiaoning often exposes his audience to it. "If we don't impress the audience, who are without the painful experience of war, with the cruel injury to life and human nature war causes, how can we bring them a love of peace and objection to war?" asked the director with a glance in his eyes. After Red River Valley and Lover's Grief over the Yellow River, both of which star Chinese model and actress Ning Jing, Feng drew a satisfactory full stop to his war trilogy last month with Purple Sunset. The film tells a story which took place in 1945, at the very moment when World War II was drawing to an end. A Chinese peasant and a Soviet woman soldier flee into a forest, where they seize a Japanese girl. They follow the girl in the hope that she will take them out of the forest, but instead they arrive in a Japanese base. Humanity prevents them from killing the young, innocent victim of Japanese militarism. This humanity, the longing for peace and eagerness to survive, make the three unite. "If people are touched by justice, tolerance and unselfishness, I think I have achieved my goal," Feng said. Feng admits that there are violent and bloody scenes in the film, such as tanks fighting and Japanese burning Chinese people alive, to show the cruelty of the war. But that's never his personal preference, he says. "Everyone who has watched my films can tell how much I hate war," he said. "I wrote all the things for my war films by myself. Whenever I finished one, I felt as though I had suffered great pain." Feng regards every one of his productions as an opportunity to learn about human nature and humanity. In spite of violent scenes which frighten and sicken the audience, a balance is sought with beautiful scenery. Just like the snowy mountains in Red River Valley and the grand plateau in Lover's Grief over the Yellow River, a beautiful vast grassland appears in this film. "I used to study art, and I appreciate beautiful things," Feng said. "I believe that films should offer the audience a chance to enjoy beauty."
Answer: he dreamed of becoming a world-famous director
Example Output:
Director Feng Xiaoning shot war film because _ .
