Read the article and select the best answer. Article: The average temperature around the world is rising. People living in the US Midwest might find this fact hard to believe, though. Two new studies show that in America's heartland, summers are now cooler and wetter than they were in years past. The scientists suggest that the change in the Midwest climate may have happened because of farming. The first study was led by David Changnon, a climatologist at Northern Illinois University in DeKalb. A climatologist studies the climate of an area, which includes measuring rainfall, temperature and wind. Climatologists want to know how these factors have changed in the past, and how they'll change in the future. Changnon and his team studied temperature records from Chicago and 13 other sites in the Midwest. "These two changes--lower temperatures and more rainfall--may be connected by humidity," Changnon says. Humidity is the measure of how much moisture is in the air. Humid air, which contains a lot of moisture, takes longer to heat up than dry air. So where did the extra _ in the air come from? Changnon points to farms in the region. As plants grow, they pull moisture from the ground and release it into the air. And among plants, soybean and corn plants release a lot of moisture. Midwestern farms now plant more soybeans and corn than in the past, with 97 percent of farmland today planted with these two crops. He also notes that the plants are planted closer together now than they used to be, so there are more plants per acre than in the past. The second study was led by famous scientists from the US. The researchers studied a vast area of the United States that stretches from South DaKota to Oklahoma and the Texas panhandle. They found that in 1930, farmers in that region irrigated only about 1.8 million acres of farmland, an amount roughly half the size of Connecticut. In 1980, however, farmers irrigated nearly 15 million acres--more land than Vermont and New Hampshire combined. Question: The best title for the article is _ .

Read the article and select the best answer. Article: A 15-year-old Saanich student who invented a flashlight powered by body heat is heading home today from California with a big prize--and an opportunity to expand on her work. St. Michaels University School student Ann Makosinski was the only Canadian among the four winners at Google's annual international science fair, beating out thousands of other young scientists from around the world. Winning the international contest was "a total shock", Ann said from San Francisco. "I definitely think it will have an influence on my future." Ann thanked her family for encouraging her interest in science, telling the judges that her first toy was a box of transistors . Ann's prize includes a $25,000 scholarship and a "once-in-a-lifetime experience" from either the European Organization for Nuclear Research, Lego or Google for her Hollow Flashlight, which has no moving parts or batteries. Ann created the flashlight for a local science fair. The inspiration for the invention came from seeing unwanted batteries and after visits to the Philippines, where she saw the need for a battery-free flashlight. A friend at school there failed in her studies because of a lack of electricity and light to study when it became dark. In her project, Ann wrote that she "made two flashlights that do not use any batteries, harmful chemicals, or kinetic energy . They do not create any noise and will always work. The flashlight's only limitation is its need for at least a 5degC temperature difference to provide usable light." A You Tube video of Ann explaining how she created the flashlight has been viewed more than 1.4 million times. Despite her success, the private school student is undecided about her career path. Ann hopes she can find a way to combine her love of film with science. The four winners were chosen from 15 finalists from eight countries. The contest attracted thousands of entries from students in 120 countries. Question: In which part of a newspaper can we probably read this passage?

Read the article and select the best answer. Article: This brief book is aimed at high school students, but speaks to anyone learning at any stage of life. Its formal, serious style closely matches its content, a school-masterly book on schooling.The author, W.H.Armstrong, starts with the basics: reading and writing.In his opinion, reading doesn't just mean recognizing each word on the page; it means taking in the information, digesting it and incorporating it into oneself just as one digests a sandwich and makes it a part of himself.The goal is to bring the information back to life, not just to treat it as dead facts on paper from dead trees.Reading and writing cannot be completely separated from each other; in fact, the aim of reading is to express the information you have got from the text.I've seen it again and again:some-one who can't express an idea after reading a text is just as ineffective as someone who hasn't read it at all. Only a third of the book remains after that discussion, which Armstrong devotes to specific tips for studying languages, math, science and history.He generally handles these topics thoroughly and equally, except for some weakness in the science and math sections and a bit too much passion regarding history to his students, that was a hundred times more than my history teachers ever got across.To my disappointment, in this part of the book he ignores the arts.As a matter of fact, they demand all the concentration and study that math and science do, though the study differs slightly in kind.Although it's commonly believed that the arts can only be naturally acquired, actually, learning the arts is no more natural than learning French or mathematics. My other comment is that the text aged.The first edition apparently dates to the 1960s--none of the references seem newer than the late 1950s.As a result, the discussion misses the entire computer age. These are small points, though, and don't affect the main discussion.I recommend it to any student and any teacher, including the self-taught student.
