Article: If you were on the street in Mexico today you might think you were in an operating room, surrounded by doctors. You could see many concerned people with masks trying their best to stop the swine flu . And the masks aren't only being used in Mexico. A friend of mine traveling from New York City to Florida was given a mask and a pair of gloves just after he reached the airport. And another friend went to get a haircut only to be faced with a hairdresser wearing a mask! But do the masks really work? Is covering your nose and mouth the key to stopping the swine flu? To find out the truth, ABC's reporter Sharyn Alfonsi talked with germ expert Dr. Elaine Larsen. It turns out that when you sneeze the air coming out of your mouth at a speed of one hundred miles per hour carries germs which can travel anywhere around you and make people around you infected . However, whether you become infected actually depends on the weather. As Sharyn reported, when you sneeze, the germs leave your body in small drops of water coming out of your mouth. If the weather is wet, the wet air will make the small drops bigger and heavier and they drop down towards our feet. If this happens, we won't become infected. But if the air is dry, those small drops can float higher up, making it possible for them to touch someone else's nose, mouth or their mask. Larsen says the masks can stop the germs well but after a few hours, they start to get wet, holding a lot of germs they come across and causing you to breathe them in. The masks do work, but the key to stopping the germs is changing your masks often. Question: According to Para.1, in Mexico you can see that _ . Yes or no, is the answer "many people wear masks in the street"?
No

Article: A pioneer who made poor lands bloom is the winner of this year's World Food Prize. Daniel Hillel developed drip irrigation techniques that squeeze the most crop out of a drop of water, making farming possible in places where water is scarce . Farmers now rely on it in water-scarce regions from Spanish vineyards, to African onion fields, to America's fruit and salad bowl. "We in California grow about 50 percent of the fruits and vegetables of the continental United States," says University of California at Davis hydrologist Jan Hopmans. "And the reason that is possible is because of, indeed, these drip and micro-irrigation techniques." Hillel got his start in dryland farming as a pioneer in Israel's Negev Desert in the 1950s."The issue was efficient use of water," he says, "because land is available. It's extensive. Water is limited."These desert farmers did not have the luxury of running irrigation water through channels to their crops, the way farmers have since ancient times.So Hillel and others gave plants just what they needed, just where they needed it. "The idea was to apply the water little by little, the way you spoon-feed a baby," Hillel says.It worked so well that Hillel was soon traveling the world, showing others how to do it.Experts say drip irrigation is an innovation whose importance is growing, as climate change and rising population strain(......) water supplies in many parts of the world. "This is where water use, water availability, water-use efficiency and climate change and crop production all converge," Hillel says. "And this has been really the essence of my career." A career whose legacy can be measured drop by drop. Question: What makes drip irrigation seem increasingly important? Yes or no, is the answer "Water shortages."?

No

Ques: Article: Every day it seems that people are coming up with new and innovative ways to use mobile devices like cellphones and smart phones. Researchers at Princeton University are looking for new ways to measure a person's sense of _ with mobile devices. To gain a better understanding of how cellphones and other mobile devices can measure our sense of happiness, the research team conducted a study that was published recently in the journal Demography. To gather data for their study, the team created an application for mobile devices using the Android operating system. Once the app was developed, the researchers invited people to download it and take part in their study. Over a three-week period, the research team was able to collect data from some 270 participants living in 13 countries. Participants came not only from the United States, but also from other nations like Australia, Canada, China, France, Germany, Israel, Japan, Norway, South Korea, Spain, Sweden and the United Kingdom. Over the course of the study, participants received occasional text questions from the researchers that asked "How happy are you?". Along with recording their response, the app used the mobile device's built-in GPS to keep track of the participant's location. The study participants were asked to rate their current state of happiness on a scale of zero to five. As they gathered data from the information collected through the application, the researchers then were able to create new methods that could help provide a better understanding of how our surroundings can influence our emotional well-being. The researchers learned that mobile devices can provide an effective way to quickly grab information that, because of today's active lifestyle, can be difficult to record. Being able to quickly grab this information was something the researchers felt was important. They said feelings and emotions that were recorded as they were happening were most likely to be more honest and precise than using other methods like writing down how they felt on a... Question: What did the researchers find vital as to rate people's sense of happiness from the passage? Yes or no, is the answer "Recording people's feelings and emotions quickly."?
Ans: No

Ques:Article: Doctors have known for a long time that extremely loud noises can cause hearing damage or loss. The noise can be the sound of a jet airplane or machines in factories of loud music or other common sound at home and at work. A person only needs to hear the noise for little more than one second to be affected. An American scientist has found that using aspirin increase the temporary hearing loss or damage from loud noise. He did an experiment using a number of students at a university who all had normal hearing. He gave them different amounts of aspirin for different periods of time, then he tested their hearing ability. He found that students who were given four grams of aspirin a day for two days suffered much greater temporary hearing loss than those who did not use aspirin. The hearing loss was about two times as great. The scientist said millions of persons in the U.S. use much larger amounts of aspirin than were used in his experiment. He said these persons face a serious danger of suffering hearing loss from loud noise. Question: Doctors have long known that _ . Yes or no, is the answer "one may lose his hearing when he hears a terribly loud noise."?

Ans:
No
