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: Despites its advantage, we are still not sure of something about E-DNA. That is _ . Yes or no, is the answer "the lasting time and the spreading area of E-DNA"?
No

Article: For Yali Liu, the hardest thing about UK higher education is having to go to the pub. "It's how much you need to invest socially with other students," she says. "I don't like going to a pub or club, but people just keep going out and I feel the pressure to go out too." This is because, unlike in China, she says, there is so much emphasis during the course on teamwork and group projects, so socialising with other students - especially British people, is crucial. Liu, 23, who is in her final year of a BSc in business administration at the University of Bath, is one of more than 80,000 Chinese students studying in UK universities. They are responsible for a large proportion of the more than PS10bn a year that international students contribute to the UK economy. However, research shows that where their academic attainment is concerned, the picture is not satisfactory. While nearly 58% of all students - and 45% of overseas students graduated with a first-class degree last year, this was true of only 35% of students from China. To find an explanation, Zhiqi Wang and Ian Crawford, lecturers at the University of Bath, compared the performance of Chinese and British undergraduates in each year of their degree. Taking a sample of 100 British and Chinese students and comparing their average marks and final degree classification, they found a dramatic drop in performance among the Chinese students between year one, when they performed better than their UK counterparts, and year two, when they performed worse. They believe the drop results from two factors. First, Chinese students fail to adapt their approaches to learning and so their performance declines in the later years when the complexity of the work increases. Second, many young people in China enroll in higher education due to pressure from family rather than their own motivation. Professor Sedghi thinks part of the problem may be the changing socio-economic background of Chinese undergraduates. While 85% of Chinese students at British universities before 2000... Question: Which of the following is NOT a possible factor for Chinese students' unsatisfactory attainment? Yes or no, is the answer "They are too young and mostly come from poor families."?
(Answer)
Yes

Ques: Article: Should e-cigarettes (electronic cigarettes) be a new choice for the smokers trying to get rid of the habit? Reactions from Americans are mixed. More than half of the people questioned in a survey think e-cigarettes should be controlled by the US Food and Drug Administration, but 47 percent believe the e-cigarettes should be available to the smokers who want to quit. "In the hunt for a safter cigarette, e-cigarettes are becoming a popular choice among those either trying to quit."or looking to replace standard tobacco smoke with an alternative that manufacturers claim to be safer, "Zogby International, which conducted the survey, said in a statement. About half of the 4,611 adults who took part in the survey had heard about e-cigarettes, which are battery-powered, or rechargeable cigarettes that vaporize a liquid nicotine solution. They do not produce smoke but a water vapor without smell. Sold mostly on the Internet, e-cigarettes were first made in China. Last year the World Health Organization (WHO) warned against using e-cigarettes, saying there was no evidence to prove they were safe or helped smokers break the habit. The WHO said people who smoke e-cigarettes breathe in a fine fog of nicotine into the lungs. Nearly a third of people questioned in the survey think that e-cigarettes should be allowed in places where smoking is forbidden, because they don't produce smoke, but 46 percent disagree. Men who were aware of the availability of e-cigarettes were more likely than woman to say they should be a choice available to smokers who want to quit. Young people, aged 18-29, and singles were the groups most open to trying e-cigarettes. Smoking is the single largest cause of preventable death worldwide, according to the WHO. Question: According to Zogby International, e-cigarettes _ . Yes or no, is the answer "are popular among people who want to quit smoking"?
Ans: No
