Example Input: Article: For a writer, there is hardly any greater honor than winning the Nobel Prize for literature. And for a woman writer, claiming the prize is even harder, for only eight women once won it. Austria's Elfriede Jelinek is the ninth and the first since 1996. The Stockholm-based Swedish Academy announced last Thursday that Jelinek won this year's Nobel Prize in literature. She is recognized for her socially critical novels and plays. Jelinek, 57, made her literary debut in 1967. She has written plays, novels and poetry. She is best known for her autobiographical 1983 novel "The Piano Teacher", made into a movie in 2001. The basic theme of her work is the inability of women to live as people beyond the roles and personalities traditionally expected of _ . Her characters struggle to lead lives not normally acceptable in society. "The nature of Jelinek's texts is often hard to define. They shift between prose and poetry and songs, they contain theatrical scenes and film script," said the academy. The Nobel Prize was founded by Swedish inventor Alfred Nobel. Nobel died in 1896 and left his fortune of about US $920 million to a fund to honor people who have helped other human beings. This year each prize is worth US $13 million.

Example Input: Article: We don't have beds in the space shuttle, but we do have sleeping bags. During the day, when we are working, we leave the bags tied to the wall, out of the way. At bedtime we untie them and take them wherever we've chosen to sleep. On most space shuttle flights everyone sleeps at the same time. No one has to stay awake to watch over the space plane: the shuttle's computers and the enginers at the Control Office do that. If anything goes wrong. The computers ring a warning bell and the engineers call us on the radio. On the space shuttle, sleep-time doesn't mean nighttime. During each ninety-minute flight around the earth, the sun "rises" and shines through our windows for about fifty minutes: then it "sets" as our flight takes us around the dark side of the Earth. To keep the sun out of our eyes, we wear black sleep masks. It is surprisingly easy to get comfortable and fall asleep in space, and we sleep differently. Some sleep upside down, some sideways, some right side up. When it's time to sleep, I take my bag, my sleep mask, and my tape player with earphones and float up to the flight platform. Then I get into the bag, and float into a sitting position just above a seat, right next to a window. Before I pull the mask down over my eyes, I relax for a while, listening to music and watching the Earth go by under me. When I'm in space I don't need as much sleep as I do on Earth Maybe that's because when I am weightless, I don't feel as tired. Or maybe it's because I'm excited to be in space and don't want to waste time sleeping.
Question: What do the shuttle people do with their sleeping bags while working?
Options: (A) Keep them where they work. (B) Leave them where they sleep. (C) Place them on the beds. (D) Fix them to the wall.
Example Output:
D
