Please answer this: Write a multi-choice question for the following article, with the given choices and answer: 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... Options: A you are likely to find information about a species with a little air, water, or soil B some kind of high-tech device can be used to test for breathable air or signs of life C you are able to get answers more efficiently, safely though with more damage D the cost of gene sequencing has been reduced greatly in recent years. Answer: A you are likely to find information about a species with a little air, water, or soil Question:

Answer: What has made E-DNA magic is that with E-DNA _ .

Problem: Write a multi-choice question for the following article, with the given choices and answer: Article: "Joe? Is chat you?" The woman speaking to me at he baseball game looked somewhat familiar, "Marci? " "It IS you ! " she exclaimed, smiling broadly. "God, it's good to see you again !" It was good to see Marci, too. Very often during the past few decades, I've wondered about her, I almost tried to reach her a few years ago after talking to a shared friend, who had indicated that the 1990s had been pretty rough for Marci. So, running into her at the baseball game was, at the very least, just happening by chance. We spent a few minutes talking about the business of our lives: kids and grandkids, husbands and houses, education and recreation. It's always a little upsetting to see how few words are required to summarize 32 years of living. We played a little "have you seen...?" and "did you know,..?" And we recalled the good old, bad old days we used to spend together. Then Marci grew quiet for a moment, looking out over the crowd walking about the marketing area at the stadium. "You know, Joe." she said, "I've always wanted to tell you...how...you know...how sorry I am for the way I treated you." Hearing that, I felt I was suffering extreme embarrassment. One does not like to remember when one has been rid of by others roughly and suddenly. "It's OK." I said. "No big deal." At least, I thought to myself, not now. "But I was so stupid: she continued. Yes, you were. I thought. "We were both pretty young:' I said. "I know," she said. "But that's no excuse for..." She hesitated. then continued. "It's just always bothered me, remembering how mean I was to you.And I've wanted to tell you that I'm sorry. So...I'm sorry." The smile on her face was warm and sincere, and there was something in her eyes, it looked a lot like relief-- _ since she had played Wif'fle ball with my heart. "OK:'I said. "Apology accepted! Overcome by the sweetness of the moment. I reached an arm around her and gave her a quick hug Just then, the... Options: A surprised and delighted B embarrassed and sorry C sensitive and curious D upset and concerned Answer: A surprised and delighted Question:

A: When Joe and Marci saw each other by chance at a stadium, they both felt _ .

Q: Write a multi-choice question for the following article, with the given choices and answer: 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. Options: A It has intuitive interface. B It is easy to operate. C Beginners can use it without similar experiences. D People can use it as a way to do mental exercise. Answer: D People can use it as a way to do mental exercise. Question:
A:
Which of the following is NOT an advantage of the iPad?
