Article: Many science fiction stories tell about explorers arriving in a new world. The explorers then use some kind of high-tech device to test for breathable air or signs of life. But here on Earth, science fiction is becoming reality through a new sampling technology called environmental DNA, or e-DNA for short. Scientists can use it to identify rare or invasive species, study bio-diversity or estimate fish populations with just a little air or water. Ryan Kelly is an ecologist at the School of Marine and Environmental Affairs at the University of Washington in Seattle. He works in a laboratory there with other researchers. They study the genetic material released by living creatures. "Essentially we can take a sample of soil or air -- and in our case -- water, and we can sequence(to arrange the order of genes)the DNA out of it and tell you what is there." Ryan Kelly says he and his research team are studying water samples collected from Puget Sound. He says the cost of gene sequencing has "been reduced greatly in recent years." That makes DNA testing more widely available. Environmental DNA can be used in two ways. One is to identify the creatures that live in a certain place. The other is to confirm the presence or lack of a specific creature. Caren Goldberg heads the new e-DNA lab at Washington State University in Pullman, Washington. She is one of the first biologists in the northwestern United States to take the technology from the testing phase to actually using it. "It is extremely useful for species that are really hard to find. I have spent many hours looking for species that I was pretty sure were there -- looking under rocks, looking in water, doing all kinds of surveys." Caren Goldberg sees e-DNA as a way to get answers more efficiently, safely and with less destruction compared to traditional survey techniques. Until recently, scientists depended on diving deep, netting or using an electric current to temporarily catch fish. "We're absolutely at this point where proof-of-concept has been established. I... Question: What has made E-DNA magic is that with E-DNA _ . Yes or no, is the answer "you are likely to find information about a species with a little air, water, or soil"?
No

Article: There are many famous museums throughout the world where people can enjoy art. Washington, D.C. has the National Gallery of Art; Paris has the Luvre; London, the British Museum. Florida International University (FIU) in Miami also shows art for people to see. And it does so without building, or even a wall for its drawing and paintings. FIU has opened what it says is the first computer art museum in the United States. You don't have to visit the University to see the art. You just need a computer linked to a telephone. You can call the telephone number of a university computer and connect your own computer to it. All of the art is stored in the school computer. It is computer art, produced electronically by artists on their own computers. In only a few minutes, your computer can receive and copy all the pictures and drawings. Robert Shostak is direction of the new computer museum. He says he starts the museum because computer artists had no place to show their works. A computer artist can only record his pictures electronically and send the records to others to see on their computers. He can also put his pictures on paper. But to print good pictures on paper, the computer artist needs an expensive laser printer . Robert Shostak says the electronic museum is mostly for art or computer students at school and universities. Many of the pictures in the museum are made by students. Mr Shostake said the FIU museum will take computer art more fun for computer artists because more people can see it. He says artists enjoy their work much more if they have an audience. And the great number of home computers in America could mean a huge _ for the electronic museum. Question: To see the art in FIU museum, you need _ . Yes or no, is the answer "a computer connect to the museum by telephone line"?
Yes

Q: Article: The food we eat seems to have great effects on our health. Although science has made great steps in making food more fit to eat, it has, at the same time, made many foods unfit to eat. Some research has shown that perhaps eighty percent of all human illnesses are related to diet and forty percent of cancer is related to diet as well. Different cultures are subject to certain illnesses because of the food that is characteristic in these cultures. That food is related to illness is not a new discovery. In 1945, government researchers realized that nitrates and nitrites , commonly used to keep color in meats, and other food additives, caused cancer. Yet, these additives remain in our food, and it becomes more difficult all the time to know which things on the packaging labels of processed food are helpful or harmful. The additives which we eat are not all so direct. Farmers often give penicillin to cows and chick and because of this, penicillin has been found in the milk of treated cows. Sometimes similar drugs are given to animals not for medicinal purposes, but for financial reasons. The farmers are simply trying to fatten the animals in order to get a higher price on the market. Although the FDA has tried repeatedly to control these, the practices continue. Question: What are nitrates used for? Yes or no, is the answer "They keep the color in meats."?
A: Yes

Article: Yasuda is 95 years old. Looking for easier ways to search the Web and send email, he bought Apple's iPad. The company has sold 3.27 million iPads since they entered the market in April. Although it's impossible to know with certainty how many seniors are buying them, evidence suggests that it's a hit with seniors. The iPad's intuitive interface makes it attractive to seniors around the world, says Takahiro Miura, a researcher at the University of Tokyou. "The iPad is a good tool for seniors because it's very easy to use," he says. "Unlike the PC, it doesn't require former knowledge." James Cordwell, a researcher in London, says the iPad's popularity with seniors is helping Apple reach beyond its traditional base of young customers. "The world's population, especially in developed markets, is getting older. It's probably a market where Apple has least entered, " Cordwell says. Senior users are "a key source of growth for them in the future." Seniors make up about 22 percent of the population in Japan. They may prove that seniors are willing to accept the iPad. Besides the customer group under 30, they spend more than any other group in the country, according to a report. Motoo Kitamura, 78, a former gas salesman, bought an iPad to help him communicate with his 2-year-old grandson and prevent him from experiencing some of the mental problems that sometimes come with getting older. "Trying new things like that is good mental exercise," he says. Question: Which of the following is NOT an advantage of the iPad? Yes or no, is the answer "People can use it as a way to do mental exercise."?
No
