Problem: OPTIONS:
- bacteria disappear in the inner part of ice
- bacteria must be also alive on other planets
- bacteria can grow in extreme weathers
- bacteria grow by breaking themselves down
Q: Read the following article and answer the question. Article: Lots of bacteria can grow in the seemingly unfriendly environment under glaciers , a region formerly considered free of much biology. This finding by glaciologists working in Switzerland could help solve some puzzles of the last ice age and point the way for finding life on other planets. Bacteria with odd lifestyles have been under increasing study lately, with most research focused on the species which prefer hot homes. The new study shifts attention to the other end of the thermometer . The exciting thing is the idea of pushing the window of acceptable bacterial environments a little bit farther open. Researchers have previously collected small numbers of bacteria from ice in Antarctica and Greenland, but they could not determine whether these were active bacteria or just frozen cells blown in by wind. In contrast, the earth beneath two Swiss glaciers harbors large colonies of bacteria--hundreds of millions of cells per gram--that appear to be growing at 0degC. Scientists followed upon these findings by taking samples of ice, water, and earth at two mountain glaciers. They found that earth beneath the glaciers contained much larger populations of bacteria than did surface and inner part of ice. Those findings indicate that the bacteria were growing at the bottom of the glacier and are not something washed in while the scientists drilled through the ice. Looking at the bacteria under a microscope , the researchers found that many were in the process of dividing, and healthy under the ice. The bacteria might break down minerals and plant remains originally buried beneath the glacier or later washed in by water going slowly through the ice, scientists say. "Some of the assumptions we have made in the past now must be seriously questioned," say researchers. "If bacteria can live under glaciers on Earth, why not on other planets? The new study points out in many ways that the bottoms of glaciers are probably quite good environments from the point of view of bacteria. So, maybe the bottom of the ice sheets on...

Read the following article and answer the question. Article: Pearl Buck(1892--1973)was born in Hillsboro, West Virginia. She grew up in China, but was educated at Randolph-Macon Woman's College. After her graduation she returned to China and lived there until 1934 with the exception of a year spent at Cornell University, where she took an MA in 1926.Pearl Buck began to write in the twenties; her first novel, East Wind; West Wind, appeared in 1930.It was followed by The Good Earth (1931),Sons(1932),and A House Divided(1935),together forming a trilogy on the stories of the family of Wang. The Good Earth stood on the American list of bestsellers for a long time and earned her several awards, including the Pulitzer Prize and the William Dean Howells Medal. She also published The first Wife and Other Stories(1933),All Men are Brothers(1933),The Mother(1934),and This Proud Heart(1938).The biographies of her mother and father, The Exile and Fighting Angel, were published in 1936 and later brought out together under the title of The Spirit and the Flesh(1944). Pearl Buck's works after 1938 are too many to speak about. Her novels have continued to deal with the differences between East and West. Her interest has spread to such countries as India and Korea. Pearl Buck was active in many charity organizations; in particular she set up an organization for the adoption of Asian-American children and took an active interest in children with low IQ. Question: According to the passage, Pearl Buck was interested in _ . Answer:
****
A: doing charity work

Read the following article and answer the question. Article: Your glasses may someday replace your smartphone, and some New Yorkers are ready for the switch. Some in the city can't wait to try them on and use the maps and GPS that the futuristic eyewear is likely to include. "I'd use it if I were hanging out with friends at 3 a. m. and going to the bar and wanted to see what was open," said Walter Choo, 40, of Fort Greene. The smartphone-like glasses will likely come out this year and cost between $250 and $600, the Times said, possibly including a variation of augmented reality, a technology already available on smartphones and tablets that overlays information onto the screen about one's surroundings. So, for example, if you were walking down a street, indicators would _ showing you the nearest coffee shop or directions could be plotted out and come into view right on the sidewalk in front of you. "As far as a mainstream consumer product, this just isn't something anybody needs," said Sam Biddle, who writes for Gizmodo.com. "We're accustomed to having one thing in our pocket to do all these things," he added, "and the average consumer isn't gonna be able to afford another device that's hundreds and hundreds of dollars." Google publisher Seth Weintraub, who has been reporting on the smartphone-like glasses since late last year, said he is confident that this type of wearable device will eventually be as common as smartphones. "It's just like smartphones 10 years ago," Weintraub said. "A few people started getting emails on their phones, and people thought that was crazy. Same kind of thing. We see people bending their heads to look at their smartphones, and it's unnatural," he said. "There's gonna be improvements to that, and this is a step there. " Question: According to Sam Biddle, the smartphone-like glasses are _ . Answer:
OPTIONS:
- necessary for teenagers
- attractive to New Yorkers
- available to people worldwide
- expensive for average consumers
expensive for average consumers

input: OPTIONS:
- To tell us that Information Technology is developing fast.
- To persuade us to resist counterfeit goods.
- To advise us to use phone apps while going shopping.
- To inform us that phone apps can help stop counterfeiters' trade. Now, answer this question: Read the following article and answer the question. Article: Counterfeit goods, or false versions of products, may cost the government of Kenya as much as $1 billion each year. The fake goods also hurt business owners who find it hard to keep customers. But information technology is being used to try to stop the problem. Jemima Mwafigu is a 34-year-old businesswoman who sells products like perfume. But in the first year of running her business, she found it hard to keep customers because of counterfeit goods. Ms. Mwafigu says her business has improved since she began using a smart phone application called Barcode Scanner. The app is used to authenticate products. It checks to make sure the products are not counterfeit. "With this application I'm able to scan the bar codes of each perfume and instantly I get the production date, the _ and I'm able to know the safety," she says. "That way, I have confidence in selling to my customers." In 2010, Kenya created the Anti-Counterfeit Agency, or ACA, to fight against illegal trade. The ACA has successfully asked government officials for stronger punishments for counterfeiters. Agnes Karingu is the agency's acting director for research and awareness. She says the ACA is trying to stay one step ahead of those making fake goods. "We are also looking into IT solutions where we can be able to use SMS programs, bar codes and information sharing," she says. "The end users of the products will actually be able to get the authentication information, and this information comes back to ACA and intellectual property rights holders." The agency is testing another program called Allvirtuous. The application is another way to find out if a product is real or not by scanning its barcode. The barcode information is sent to a database. Then a result is sent back to the app. The International Chamber of Commerce is a global business organization. It says the value of counterfeit goods produced around the world is expected to be more than $1.7 trillion this year. Question: What's the main purpose of this passage? Answer:
A:
output:
To inform us that phone apps can help stop counterfeiters' trade.
