input: Please answer the following: Write a multi-choice question for the following article: Article: What do astronauts eat in space, and why? How did astronaut food come into being? How do astronauts preserve food for long periods of time in space? NASA(the National Aeronautics and Space Administration) has been researching food for space travel since the 1960's to find the best way of keeping astronauts from going hungry. The research could date from an accident that took place on the first manned Gemini mission in 1965. astronaut John Young managed to sneak a corned beef sandwich onto the Geminni III capsule to eat during its orbit around Earth. To Young's surprise, the sandwich plan did not go as expected; instead the sandwich began to break apart and scatter through the Geminni IIIcapsule. This could have resulted in disaster, since a small piece of food could have stuck in the air vents and other equipment. The sandwich was stuffed into a pocket to avoid the further mess inside the small space capsule This incident caused NASA to enforce strict rules on what types of food can be taken into space. Space food has come a long way since then. During the Gemini period, the astronauts mostly ate cubed, compressed foods high in calories and lightweight. NASA expects a long shelf life for space food. The majority of food taken into space has been dried out or heat-treated. These process and use of sodium , make the food taken into space last longer. Research is ongoing into space food to seek out healthier ways to preserve it. Too much sodium is unhealthy, and can badly change the taste of some foods.

Please answer this: Write a multi-choice question for the following article: Article: Well, parents, surprise! Lots of us are using Twitter and Facebook to thumb rides, and not just to school. It's awkward to be refused when you call a friend and ask for a ride. But with Twitter, you just look for other people heading the same way. It may sound risky, so many teens stay within their own social circles to find rides, and don't branch out beyond friends when asking on Twitter just like me, but to some young people, especially those taking longer trips, stranger danger is less of a concern. "I think the digital connection of young people is really key, because younger generations grew up sharing things on line, sharing files, photos, music, etc, so they've been very used to sharing," said Juliet Schor, a sociology professor at Boston College. The sharing economy got big during the recession , allowing people to access more goods, services using technology and even to share costs. And that technology, for me, is what the car was for my mom, a gateway to more freedom, like what my friend Earl says, "The symbol of freedom isn't the car any more because there's technology out there connecting you to a car." According to the researchers at the University of Michigan, 30 years ago, eight in ten American 18-year-olds had a driver's license compared to six in ten today. So it's not that surprising that on my 16th birthday I wasn't rushing to get a license but an iPhone. "Driving, for young people, does mean they have to disconnect from their technology, and that's a negative. So if they could sit in the passage side and still be connected, that's going to be a plus." Schor continued. To me, another plus is that ridesharing represents something, something much bigger than trying to save money. I see it as evidence that people still depend on each other. My generation shares their cars and apartments the way neighbors used to share cups of sugar. For the system to work, some of us still need our own cars. But until I get my own version of the silver Super Beetle, you can find me on Twitter.

input question: Write a multi-choice question for the following article: Article: "Just take a deep breath." "Don't think about it." "You're more likely to die in a car wreck on the way to the airport than you are in a plane crash." These are just some words given to people with a fear of flying. But as Tom Cruise, playing Lt. Daniel Kaffee in the movie A Few Good Men, said, "I get sick when I fly because I'm afraid of crashing into a large mountain. I don't think Daniel will help." But there's a new application that just may. Today, the VALK Foundation, a Dutch group that's a partnership between KLM Royal Dutch Airlines and the University of Leiden, launches the app in the US. The VALK Foundation was one of the first centers for research and fear-of-flying treatment in the world and is the organizer of three world conferences on fear of flying.The foundation said the app, called Flight App VALK, is the first scientifically-developed, web-based treatment for people who suffer from mild to moderate fear of flying. "The fear of flying application we have created aims to transfer all of the knowledge we have developed through our program into a mobile application that will help ease travelers' fears," said Dr. Lucas van Gerwen, director of the VALK Foundation. Dr. van Gerwen is also a psychologist and professional pilot with more than 30 years experience. The foundation said up to 30% of adults are fearful fliers. The Flight App is designed to help relax passengers before and during flights by educating users about flight safety and turbulence. It explains the sounds and sensations they can expect during departure, flight and landing. And, if a passenger's flight stress reaches a panic level, they press a special panic button which provides audio and written information to help decrease stress levels. Most importantly, the Flight App can be used during the flight in the airplane mode. Once downloaded, the program does not require Internet connection in the air.???
