Question: Write a multi-choice question for the following article, with the given choices and answer: Article: While astronauts in space get to do many exciting things, they miss out on ordinary things that we all take for granted--being able to walk on firm ground, hanging out with family and digging into a slice of hot steaming pizza. Though not much can be done about the first two things, there may soon be a solution to the third one, thanks to this cool 3-D pizza printer! About a year ago, NASA offered $125 ,000 to Anjan Contractor, a 3-D technology expert, to build a device that would allow astronauts to make pizza on demand. The mechanical engineer promised that his invention would produce pies in large quantities that looked, tasted and even smelled like pizza made in common ovens. Late last year, the engineer presented a video of his first prototype that begins by creating a single slice of dough that is cooked and printed at the same time. Then comes the tomato "sauce" -- a mix of tomato powder, oil and water and finally, a protein slice that resembles cheese. While the video doesn't show the baking process, the inventor says that once the pizza is printed, it can be ready to be consumed in 7 seconds. While the pie in the video looks delicious enough to attract any pizza lover, Anjan Contractor is far from ready for astronauts. That's because he still has to find a solution to make the food container in the printer last for 30 years. Though that may sound unrealistic, actually it is not. Anjan Contractor believes that the only way that is possible is that the water is removed from all the ingredients and then they are reduced to the powder form. This, as you can imagine, will not be so easy. But, while the printer may not be ready for space, it certainly looks ready enough for people on earth. Hopefully, NASA and Contractor will consider selling it to those not fortunate enough to go to Mars! Options: A NASA is trying its best to help astronauts eat better B Astronauts may soon be able to enjoy steaming hot pizza C NASA is working on making pizza for common people D A 3-D pizza printer has been used to make pizza Answer: B Astronauts may soon be able to enjoy steaming hot pizza Question:

[Q]: Write a multi-choice question for the following article, with the given choices and answer: Article: Cell phone use and texting are increasingly common, especially among teens. And that could be a problem. Texting affects learning and performing on test, a new study finds. So a Montana teen, Colin decided to test that. They asked 47 classmates to take part in a two-part experiment. The goal was to test how well these students understood written material. Each one had to read a paragraph or two about a certain topic, then answer questions about it. In the first part, the participants had 15 minutes to understand and then answer questions about six readings. Throughout this test, they met no distractions. During a new set of readings, the brothers sent messages to the participants' cell phones every 90 seconds. In each message, there were questions that required a reply. Participants should have scored better on the second test because it was easier. In fact, they scored worse when distracted by messages. Only a few students scored as well when replying to messages as they did when undistracted. But importantly, nobody performed better during the texting part. The brothers presented details of their findings at the Intel International Science and Engineering Fair. Boys and girls scored equally poorly while texting, the brothers noticed. Older participants didn't do any better than younger ones. And it didn't matter if a student thought he was good at multitasking. On average, the brothers found that even students who were confident of their abilities did just as poorly while texting. Surprisingly, even though the students remembered less of what they read while texting, most of them answered questions in messages perfectly. "Our teachers are very happy to see these results," says Coler. The teens' new data strongly support their teachers' opinion that texting while studying is a serious distraction. Options: A Cell phone use and texting are more common. B Teens should avoid cell phone use and texting. C Texting affects students' performance on test. D The effect of texting differs from person to person. Answer: C Texting affects students' performance on test. Question:

input: Please answer the following: Write a multi-choice question for the following article, with the given choices and answer: Article: "Long time no see" is a very interesting sentence. When I first read this sentence from an American friend's email, I laughed. I thought it was a perfect example of Chinglish. Obviously, it is a word-by-word literal translation of the Chinese greetings with a ruled English grammar and structure! Later on, my friend told me that it is a standard American greeting. I was too thrilled to believe her. Her words could not convince me at all. So I did a research on google.com. To my surprise, there are over 60 thousand web pages containing "Long time no see." This sentence has been widely used in emails, letters, newspapers, movies, books, or any other possible places. Though it is sort of informal, it is part of the language that Americans use daily. Ironically, if you type this phrase in Microsoft Word, the software will tell you that the grammar needs to be corrected. Nobody knows the origin of this Chinglish sentence. Some people believe that it came from Charlie Chan's movies. In the 1930s, Hollywood moviemakers successfully created a world wide famous Chinese detective named "Charlie Chan" on wide screens. Detective Chan likes to teach Americans some Chinese wisdom by quoting Confucius. "Long time no see" was his trademark. Soon after Charlie Chan, "Long time no see" became a popular phrase in the real world with thanks to the popularity of these movies. Some scholars refer to America as a huge pot of stew. All kinds of culture are mixed in the stew together, and they change the color and taste of each other. American Chinese, though a minority ethnic group in the United States, is also contributing some changes to the stew! Language is usually the first thing to be influenced in the mixed stew. You can have some other examples than adoptions from Chinese, such as pizza from Italian, susi from Japanese, and deja vu from French etc. There is a long list! Americans do not just simply borrow something from others. They will modify it and make it their own, so you would not be surprised to find a tofu and peanut... Options: A some Chinese expressions are introduced into English B you'll not be surprised at a tofu in a restaurant in America C some American expressions can be used in China D American English keep being enriched from different cultures Answer: D American English keep being enriched from different cultures Question:
