Article: Here are many kinds of vacations. People can go traveling abroad or spend their holidays at the seaside. One kind of vacation is camping. Many Americans enjoy going camping because it is good for them. Each summer millions of Americans drive to the countryside where they find places to camp. There are a lot of national parks in the USA and these national parks mostly stand on the mountains. They are people's favorite camping places. Campers are free from the busy life in the noisy and crowded city. They throw themselves into the arms of Mother Nature. They enjoy the fresh air, lakes and forests in these parks. Hiking, swimming and fishing are the main kinds of exercise. They can see different sorts of animals and plants there. Some campers have trailers which they pull behind their cars to the camping places. Trailers are like small houses on wheels, having many of the things that people use in their homes, such as electricity, hot water, kitchen tools and things like that. But most campers don't have trailers. Tent campers lead a very simple but healthy life. Camping is a pleasant sports activity. After living a while in the open, campers become as fresh as paintings. They feel relaxed. Question: According to the passage, what do many Americans get from camping? Yes or no, is the answer "Health and happiness."?
No

Article: Could cities that float on the sea solve the problems caused by floods and provide food for the world? Some scientists think so. The idea is already being tested and they believe that floating citied will provide more homes for a growing population, without having to use land needed to grow food. And they believe floating areas will allow more food to be grown, so that no one in the world is hungry. In some places, cities that float on the sea are already being planned, A company in the Netherlands called DeltaSync thinks that sea cities will save the world, with more than one in ten people living in them. They say sea cities solve many of the problems the world faces in the 21st century, like not having enough land , more and more people needing homes, fossil fuels running low and the increasingly serious problems caused by floods. DeltaSync says building in the desert is not possible because there is no enough water and that developing ways for people to live in space is still too expensive. So they believe the answer is our oceans, which cover over two thirds of the Earth's surface. Their plans for floating areas include using algae to produce fuel and food. More than a quarter of the land in the Netherlands already lies underwater and scientists there have spent years trying to find ways to deal with it. In the city of Rotterdam they already have floating homes. Bart Roeffen from DeltaSync says: "We have plans for neighbourhoods including roads and, in the end, I believe we can build floating cities on the sea." Question: What is the best title for the text? Yes or no, is the answer "Will sea cities save the world?"?

Article: When I was seven, my father gave me a Timex, my first watch. I loved it, wore it for years, and haven't had another one since it stopped ticking a decade ago. Why? Because I don't need one. I have a mobile phone and I'm always near someone with an iPod or something like that. All these tell the time -- which is why, if you look around, you'll see lots of empty wrists ; sales of watches to young adults have been going down since 2007. But while these wise people have realized that they don't need them, others -- including some distinguished ones of our time -- are spending total fortunes on them. Brands such as Rolex, Patek Philippe and Breitling command shocking prices, up to PS 250.000 for a piece. This is ridiculous. Expensive cars go faster than cheap cars. Expensive clothes hang better than cheap clothes. But these days, all watches tell the time as well as all other watches. Yes, you may say expensive watches will come with some extra functions -- but who needs them? How often do you dive to 300 metres into the sea to test its function of waterproof, or need to find your direction in the area around the South Pole by using its compass? So why pay that much of five years' school fees for watches that allow you to do these things? If justice were done, the Swiss watch industry should have closed down when the Japanese discovered how to make accurate watches for a five-pound note. Instead, the Swiss re-invented the watch, with the aid of millions of pounds' worth of advertising, as a message about the man ---- usually a famous star, wearing it. Rolexes are for those who spend their weekends climbing icy mountains; a Patek Philippe is for one from a rich or noble family; a Breitling suggests you like to pilot planes across the world. Watches are classified as "investment items" now. A 1994 Philippe recently sold for nearly PS 350, 000, while 1960s Rolexes have gone from 15, 000 to 30, 000 plus in a year. But, to some wealthy people, a watch is more than an investment. It's a valuable toy for... Question: Which would be the best title for the passage? Yes or no, is the answer "Super-level Watches? Not for Me!"?
No

Article: A study published in September suggests there is a surprising way to get people to avoid unhealthy foods: change their memories. Scientist Elizabeth Loftus of the University of California at Irvine asked volunteers to answer some questions on their personalities and food experiences. "One week later," Loftus says, "we told those people we'd fed their answers into our smart computer and it came up with an account of their early childhood experiences." Some accounts included one key additional detail. "You got sick after eating strawberry ice-cream." The researchers then changed this detail into a manufactured memory through leading questions --- Who were you with? How did you feel? By the end of the study, up to 41% of those given a false memory believed strawberry ice-cream once made them sick, and many said they'd avoid eating it. When Loftus published her findings, she started getting calls from people begging her to make them remember hating chocolate or French fries. Unfortunately, it's not that easy. False memories appear to work only for foods you don't eat on a regular basis. But most importantly, it is likely that false memories can be implanted only in people who are unaware of the mental control. And lying to a patient is immoral , even if a doctor believes it's for the patient's benefit. Loftus says there's nothing to stop parents from trying it with their overweight children. "I say, wake up --- parents have been lying about Father Christmas for years, and nobody seems to mind. If they can prevent diseases caused by fatness and all the other problems that come with that, you might think that's more moral lie. Decide that for yourself." Question: What did Loftus find out from her research? Yes or no, is the answer "People can be led to believe in something false."?
No
