Read the article and select the best answer. Article: If you knew a bottle of water had been recycled from urine , would you drink it? Astronauts at the International Space Station (ISS) may soon do so. NASA said it would use a high-tech machine to recycle wastewater at the ISS. The machine will recycle everything from sweat , the water for washing hands, shower water, water used for brushing teeth, and even urine, to make drinking water. It will save NASA millions of dollars each year. At present, each ISS astronaut uses about 4.4 liters of water every day. It costs about $24 million a year to transport water up to ISS. NASA says that a liter of water costs about $11,000. The machine will be sent to the ISS in October 2008. NASA hopes it will recycle about 93% of all water used on the station. Will the water be clean? Scientists say the wastewater will go through a very complicated process . For example, different chemicals will be put in the wastewater; the water will be heated to 130degCto get rid of bacteria . The recycled water is thousands of times better than the water from a city tap, scientists say. Question: Scientists plan to get rid of bacteria in the wastewater by _ . Options: A: freezing B: heating C: shaking D: precipitating
(Answer)
B

Read the article and select the best answer. Article: What can we learn from the special, very successful people in the world who make the impossible possible? Lesson 1: Ways of creative thinking are needed Bill Gates and Mark Zuckerberg both dropped out of college. They prefer to teach themselves because they like to develop their own ways of thinking. They think standard ways of teaching might stop people from being creative and having new ideas. Lesson 2: The answer might not be what you expect Find your answers from facts -- not start with an expectation of what you will find. Stephen Jacobsen from Northwestern University believed what he was taught: that water on Earth came from icy comets or planets which hit into Earth. However, by studying a special rock, he discovered that it acts like a sponge . This suggests that Earth's water may have come from inside, driven to the surface to form the oceans, by geological activity. "I had a pretty hard time making others believe it," he said. "But thinking about the fact that you may the first person to see something for the first time doesn't happen very often. When it does, it's amazing." _ Years of planning went into a recent achievement in space travel. The European Space Agency's "Philae", a robot landing craft, met up with Comet 67P, which is 480 million kilometers away. The trip from Earth by "Philae" had taken ten years! The scientists had no idea what the surface of the comet would be like. If the landing failed, it would be impossible to get information from the spacecraft. Twenty years of work would have been wasted. When "Philae" tried to land, it bounced away from the comet's icy surface twice. Luckily, however, "Philae" landed successfully and began sending information back to Earth. Question: In Lesson 2, the writer mainly wants to tell us that _ . Options: A: we should get answers from facts B: we can believe what we are taught C: it's hard to make others believe something D: an expectation can help get an answer in research
