Ques: Read the following article and select the best answer. Article: A machine that takes sweat-laden clothes and turns the moisture into drinking water is in use in Sweden. The device spins and heats the material to remove the sweat, and then passes the vapor through a special membrane designed to only let water molecules get through. Since its Monday launch, its creators say more than 1,000 people have "drunk others' sweat(h)" in Gothenburg. They add the liquid is cleaner than local tap water. The device was built for the United Nation's child-focused charity UNICEF to promote a campaign highlighting the fact that 780 million people in the world lack access to clean water. The machine was designed and built by engineer Andreas Hammar, known locally for his appearances on TV tech show Mekatronik. He said the critical part of the sweat machine was a new water purification component developed by a company named HVR in collaboration with Sweden's Royal Institute of Technology. "It uses a technique called membrane distillation ," he told the BBC."We use a substance that's a bit like Gortex that only lets steam through but keeps bacteria, salts, clothing fibers and other substances out."They have something similar on the International Space Station to treat astronaut's urine - but our machine was cheaper to build. Volunteers have been sampling the treated sweat since the start of the week in Gothenburg ."The amount of water it produces depends on how sweaty the person is - but one person's T-shirt typically produces 10ml , roughly a mouthful." The equipment has been put on show at the Gothia Cup - the world's largest international youth football tournament. MattiasRonge, chief executive of Stockholm-based advertising agency Deportivo - which organized the stunt - said the machine had helped raise awareness for UNICEF, but in reality had its limitations. "People haven't produced as much sweat as we hoped - right now the weather in Gothenburg is lousy," he said."So we've installed exercise bikes alongside the machine and volunteers are cycling like crazy."Even so, the demand for... Question: What can we infer from the passage ? _ . - The water processed by the machine is cleaner than local tap water . - The machine can help raise awareness of lacking water in the world . - The machine is cheaper than the similar one on the International Space Station - The amount of water the machine produces is roughly a mouthful.
Ans: The machine can help raise awareness of lacking water in the world .

Ques: Read the following article and select the best answer. Article: Americans have developed an olive oil habit. Out to dinner recently, I saw a man dipping his white bread in olive oil and then pouring it all over his salad, saying, "Wow, this is so good for me!" But is olive oil the healthiest fat? No, it's not. You might ask, doesn't it lower cholesterol ? Well, only when you substitute olive oil in equivalent amounts for butter or oils that are higher in saturated fat. Olive oil doesn't lower cholesterol; it just doesn't raise it as much. You may be better off with canola oil. The 1999 Lyon Diet Heart Study found that a Mediterranean diet significantly reduced heart attacks and premature deaths. Many people attributed this to eating a lot of olive oil. But it was increased consumption of canola oil that accounted for these improvements. Also, study participants ate more whole-grain bread, vegetables, fish and fruit, and less meat. Butter and cream were replaced with man-made butter made from canola oil, which has more healthy omega-3 fatty acids than olive oil does. Another study found that olive oil reduced blood flow by 31%. Canola oil and fish oil don't. (You want to increase blood flow to all body parts.) I like the taste of olive oil, and I use it sometimes. It's a healthier fat than many others, but it's not nearly as healthy as canola oil -- or fish oil and flaxseed oil, for that matter, which also have lots of omega-3s. And a tablespoon of any oil has 126 calories. Think about that before you pour it on. Question: According to the author, olive oil _ . - isn't as health as most people think - can be used as a substitute for meat - can help increase the blood flow - contain less calories than other oils
Ans: isn't as health as most people think

Ques: Read the following article and select the best answer. Article: It's that time of year when people need to lock their cars. Is it because there are many criminals stealing cars? Not indeed. Rather, it's because of good-hearted neighbors who want to share their harvest. Sharon recently had a good year for tomatoes. She and her family had eaten and canned so many that they'd begun to feel their skin turn slightly red. That's when she decided it was time to share her blessings. Eventually she found a neighbor willing to have the tomatoes."Feel free to take whatever you want,"Sharon told her. Later that day, Sharon found that her garden had indeed been harvested. She thought it a good way to help someone and the food didn't go to waste. A few days later, the neighbor knocked at the door, holding a loaf of bread:"I want to thank you for all of the tomatoes, and I have to admit that I took a few other things and hoped you wouldn't mind."Sharon couldn't think of anything in her garden that had been worth harvesting and said so."But you did,"the neighbor said."You had some of the prettiest zucchini." Sharon was confused. She hadn't even planted any zucchini. But her neighbor insisted that there were bright green zucchini. Sharon's curiosity got the better of her and she had to go to see where the zucchini had grown. When the neighbor pointed at the long green vegetables, Sharon smiled."Well, actually, those are cucumbers that we never harvested, because they got too big, soft and bitter." The neighbor looked at Sharon, shock written all over her face. She hesitated a few times, and then smiling, held out the bread, part of a batch she had shared all over the neighborhood,"I brought you a loaf of cucumber bread. I hope you like it." Question: Why did Sharon want to share the tomatoes? - Her family's skin became red. - Her neighbors did the same thing. - There were too many to consume. - It was good for neighborhood relationships.
Ans:
There were too many to consume.
