I'm taking a test and have to guess the right answer to the question after the article. Article: For more than 40 years, scientists have sought to learn how well human beings can adapt to long periods in space. The International Space Station continues to provide valuable knowledge about spaceflight. But an earlier space station, Skylab, helped make the current space project possible. Canadian astronaut Chris Hadfield sang aboard the International Space Station on May 12, 2013. His music video has become extremely popular. The astronaut played his own version of David Bowie's song Space Oddity. He performed while floating weightlessly, with images of planet earth and space appearing in the window behind him. Chris Hadfield recently returned home after nearly five months on the space station. For him, the long flight produced a hit video on YouTube and no major physical problems. But 40 years ago, scientists did not know how humans would react to long-term spaceflight. To find out, NASA, the American space agency, launched Skylab in May, 1973. Over nearly a year, three teams of astronauts visited Skylab for stays of between 28 to 84 days. They learned how people react to extended periods in space. Gerald Carr commanded Skylab 4. He spoke at a NASA event marking the 40th anniversary of Skylab's launch. He said that the loss of the body's muscle mass was a main concern. Astronauts on Skylab used exercise equipment to stay strong. The astronauts spent their workdays carrying out experiments, including biomedical research. Marshall Porterfield is the director of NASA's Space Life and Physical Sciences Division. He says the Skylab astronauts' understanding of their own ability to deal with long-term spaceflight continues to help current astronauts. NASA says the next step for life away from Earth is a year-long space station mission, set for 2015. Question: Why was Chris Hadfield's song so special? Options: A: It was performed in space. B: It was created by an astronaut. C: It was a very familiar song. D: It was first sung by a famous singer.

I'm taking a test and have to guess the right answer to the question after the article. Article: It is widely known that any English conversation begins with The Weather.Such a fixation with the weather finds expression in Dr.Johnson's famous comment that"When two English meet,their first talk is of weather."Though Johnson's observation is as accurate now as it was over two hundred years ago,most commentators fail to come up with a convincing explanation for this English weatherspeak. Bill Bryson,for example,concludes that,as the English weather is not at all exciting,the _ with it can hardly be understood.He argues that"To an outsider,the most striking thing about the English weather is that there is not very much of it." Simply,the reason is that the unusual and unpredictable weather is almost unknown in the British Isles. Jeremy Paxman,however,disagrees with Bryson,arguing that the English weather is by nature attractive.Bryson is wrong,he says,because the English preference for the weather has nothing to do with the natural phenomena."The interest is less in the phenomena themselves,but in uncertainty."According to him,the weather in England is very changeable and uncertain and it attracts the English as well as the outsider. Bryson and Paxman stand for common misconceptions about the weatherspeak among the English.Both commentators,somehow,are missing the point.The English weather conversation is not really about the weather at all.English weatherspeak is a system of signs,which is developed to help the speakers overcome the natural reserve and actually talk to each other.Everyone knows conversations starting with weatherspeak are not requests for weather data.Rather,they are routine greetings,conversation starters or the blank "fillers".In other words,English weatherspeak is a means of social bonding. Question: The author mentions Dr.Johnson's comment to show that _ . Options: A: most commentators agree with Dr.Johnson B: Dr.Johnson is famous for his weather observation C: the comment was accurate two hundred years ago D: English conversations usually start with the weather

Q: I'm taking a test and have to guess the right answer to the question after the article. Article: Cats are creatures of habit. They like to go to sleep about the same time every day and for a certain length of time. They seem to have a natural clock inside them that tells them when to sleep. Cats increase their regular sleep with occasional cat naps . Some experts feel that humans could also benefit from this habit. Cat naps help to build up energy in the body. They are also a good way to get rid of trouble! Since cats have the same moods as humans, some experts believe that people can improve their moods. People might become happier. A number of famous people have copied cats by taking cat naps during the day. The naps would usually last from 15 to 30 minutes. Winston Churchill took cat naps. So did Presidents Harry Truman, John F. Kennedy, and Lyndon B. Johnson. These famous men were known for their energy. They were also able to work long hours, often into the night. Napping was their secret. Question: Naps usually last _ . Options: A: three hours B: less than half an hour C: forty-five minutes D: fifty-five minutes
A: B
I'm taking a test and have to guess the right answer to the question after the article. Article: Robots make me nervous--especially the ones which seem to think for themselves. I was embarrassed to admit this till I heard that Bill Gates, the founder of Microsoft, felt the same way. Gates said in an interview with the social networking and news website Reddit: "I am in the camp that is concerned about super intelligence. First the machines will do a lot of jobs for us and not be super intelligent.That should be positive if we manage well. A few decades after that though the intelligence is strong enough to be a concern." Well, maybe I don't have to worry about my computer and kitchen equipment yet. After I use them I can always pull the plug. But in the future, machines might find a way to prevent us from switching them off. There's a terrible thought! Maybe the problem with computers too clever for us is not that they are evil like some we've seen in sci-fi movies. What could put us in danger is that they might be too efficient. That's what philosopher Nick Bostrom from Oxford University believes. He says that machines are indifferent to humans and in pursuit of their own goals,the destruction of people might be just additional damage. Bostrom gives us an example: A machine which might have as its only goal to produce as many paperclips as possible might look at human bodies as extra material for paperclips and go after you. Because it is, well, a machine, it would not take pity on you. It's a good thing that American writer Isaac Asimov thought about how far robots can go and left us his three rules of robotics. They state that a robot may not hurt a human being or allow the human being to come to harm. I'm glad my machines at home are "dumb". All my cleaner wants to take over is the carpet in my living room. Let's hope they don't create an appliance which wants to take over the world!. Question: An intelligent paperclip machine would harm us because _ . Options: A: it is much cleverer than us B: it would take over the world C: it would see us just as material D: it has the strong feeling of destroying us
