Read the following article and answer the question. Article: Water runs downhill from mountaintops to streams to rivers to oceans. But downhill isn't the only way that water moves .A new study measures how water travels from country to country for human consumption. This flow isn't the type we usually think about .These scientists looked at the water used to grow and make the products which get shipped from nation to nation as imports or exports. They call this a flow of"virtual water ". We typically think about water as the liquid that flows from a tap. However,92%of the water used by people goes into growing crops,according to water researcher Arjen Hoekstra. He recently studied the hidden travels of virtual water used in products made from things like crops and meats .These products are shipped around the world. For example.consider a sugary soft drink. Hoekstra estimated that to produce one half-liter of the drink requires between 170 and 310litersofthewater--about 95%--is used to grow and process the ingredients .Another 4%goes into the packaging and labeling. In Hoekstra's calculation, when one country produces a half-liter of soda and sells it abroad,it exports as much virtual water as would fill a large refrigerator. According to Hoekstra's new report,dry countries like Israel and Kuwait,both in the Middle East, get the majority of their virtual water from other countries,through imported products. More surprisingly, some wetter countries,like the Netherlands and the United Kingdom, also get the majority of their virtual water from other places. That means that most of the water used to grow or produce the products and food consumed in those countries came from other countries. In the United States most of the virtual water used comes from American sources .In China even less of the water associated with its products Question: The passage is most probably a _ . Answer:

OPTIONS:
- science news report
- book review
- newspaper advertisement
- science fiction story

Answer: science news report

Read the following article and answer the question. Article: Andy Steele lives just a few blocks from the campus of Black Hills State University in Spearfish, S.D., so commuting to class isn't the problem. But he doesn't like lectures much, isn't a morning person, and wants time during the day to restore motorcycles. So Steele, a full-time senior business major, has been taking as many classes as he can from the South Dakota State system's online offerings. He gets better grades and learns more, he says, and insists he isn't missing out on the college experience. "I still know a lot of people from my first two years living on campus, and I still meet a lot of people," he says. But now, he sets his own schedule. At least 2.3 million people took some kind of online courses, according to a recent survey by The Sloan Consortium, an online education group, and two-thirds of colleges offering "face-to-face" courses also offer online ones. But what were once two different types of classes are looking more and more alike and often falling into the same pool of students. At some schools, online courses originally intended for non-traditional students living far from campus have proved surprisingly popular with on-campus students. A recent study found 42 percent of the students enrolled in its distance education courses were located on campus at the university that was hosting the online courses. Numbers vary depending on the policies of particular colleges, but other schools also have students mixing and matching online and "face-to-face" credits. Motives range from lifestyle to adapting a job schedule to getting into high--demand courses. Washington State had about 325 on-campus undergraduates taking one or more distance courses last year. As many as 9,000 students took both distance and in-person classes at Arizona State last year. "Business is really about providing choices to their customers, and that's really what we want to do," said Sheila Aaker, extended services coordinator at Black Hills State. Many schools, such as Washington State and Arizona State, let... Question: We can learn from the passage that Andy Steele _ . Answer:
