I'm taking a test and have to guess the right answer to the question after the article. Article: Ideas about polite behavior are different from one culture to another. Some societies, such as America and Australia for example, are mobile and very open. People here change jobs and move house quite often. As a result, they have a lot of relationships that often last only a short time, and they need to get to know people quickly. So it's normal to have friendly conversations with people that they have just met, and you can talk about things that other cultures would regard as personal. On the other hand there are more crowded and less mobile societies where long-term relationships are more important. A Malaysian or Mexican business person, for example, will want to get to know you very well before he or she feels happy to start business. But when you do get to know each other, the relationship becomes much deeper than it would in a mobile society. To Americans, both Europeans and Asians seem cool and formal at first. On the other hand, as a passenger from a less mobile society puts it, it's no fun spending several hours next to a stranger who wants to tell you all about his or her life and asks you all sorts of questions that you don't want to answer. Cross-cultural differences aren't just a problem for travelers, but also for the flights that carry them. All flights want to provide the best service, but ideas about good service are different from place to place. This can be seen most clearly in the way that problems are dealt with. Some societies have 'universalist' cultures. These societies strongly respect rules, and they treat every person and situation in basically the same way. 'Particularist' societies, on the other hand, also have rules, but they are less important than the society's unwrinen ideas about what is right or wrong for a particular situation or a particular person. So the normal rules are changed to fit the needs of the situation or the importance of the person. This difference can cause problems. A traveler from a particularist society, India, is checking in for a flight in Germany, a... Question: The writer of the passage thinks that the Indian and the German have different ideas about rules because of different _ . Options: A: interests B: habits and customs C: cultures D: ways of life

I'm taking a test and have to guess the right answer to the question after the article. 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... Question: Which of the following facts proves that bacteria under glaciers are alive? Options: A: Water is going slowly through the ice. B: The drills used by scientists are free of bacteria. C: Many of the bacteria are in the process of dividing. D: The earth beneath the glacier contains more bacteria.

I'm taking a test and have to guess the right answer to the question after the article. Article: A woman was walking her dog along a beach in New Zealand in late June when she saw something that looked like a white ball in the sand. It turned out to be a young Emperor penguin that was lost. At his age, he should have been close to Antarctic, swimming for fish and playing on the ice floes . But this penguin started swimming north and just kept going. The penguin attracted a lot of attention in New Zealand. It has been 40 years since an Emperor penguin was last seen there. Researchers at the Department of Conservation were called in. They decided to watch the penguin closely, but not to disturb it in any way. Many New Zealanders came to Peka Peka Beach to look at the elegant penguin. They were careful to keep their dogs away from it so it wouldn't be frightened. The public nicknamed the animal Happy Feet. Researchers started to notice that Happy Feet didn't seem well. It turns out that he had been eating the sand from the beach, likely thinking it was snow. The public raised more than 11,000 pounds for an operation to get the sand out of his stomach. The operation was a success, and Happy Feet was taken to a zoo in Wellington, NZ. A group of experts met to decide how to help Happy Feet return to the wild. Last Sunday, they put him on a boat called the Tangaroa, in a specially built ice-filled box and took him out into the Southern Ocean, southeast of New Zealand. There, they released him into the ocean, which is his natural habitat. He took one last look at his human helpers and then dived into the ocean. "Emperor penguins spend their first five years at sea," said Peter Simpson of New Zealand's Department of Conservation. " What happens now is up to the penguin." Happy Feet was fitted with a satellite transmitter so they can monitor his progress using the Internet. So far, the trackers shows that he swam northeast for a little while before getting his bearings and heading south. Question: The public collected some money to _ . Options: A: build a home for the penguin B: get the sand out of the penguin's belly C: do some research on the penguin D: return the penguin to his habitat
