Read the article and select the best answer. Article: We've reached a strange--some would say unusual--point. While fighting world hunger continues to be the matter of vital importance according to a recent report from the World Health Organization (WHO), more people now die from being overweight, or say, from being extremely fat, than from being underweight. It's the good life that's more likely to kill us these days. Worse, nearly l8 million children under the age of five around the world are estimated to be overweight. What's going on? We really don't have many excuses for our weight problems. The dangers of the problem have been drilled into us by public-health campaigns since 2001 and the message is getting through--up to a point. In the 1970s, Finland, for example, had the highest rate of heart disease in the world and being overweight was its main cause. Not any more. A public-health campaign has greatly reduced the number of heart disease deaths by 80 per cent over the past three decades. Maybe that explains why the percentage of people in Finland taking diet pills doubled between 2001 and 2005, and doctors even offer surgery of removing fat inside and change the shape of the body. That has become a sort of fashion. No wonder it ranks as the world's most body-conscious country. We know what we should be doing to lose weight--but actually doing it is another matter. By far the most popular excuse is not taking enough exercise. More than half of us admit we lack willpower. Others blame good food. They say: it's just too inviting and it makes them overeat. Still others lay the blame on the Americans, complaining that pounds have piled on thanks to eating too much American-style fast food. Some also blame their parents--their genes. But unfortunately, the parents are wronged because they're normal in shape, or rather slim. It's a similar story around the world, although people are relatively unlikely to have tried to lose weight. Parents are eager to see their kids shape up. Do as I say--not as I do. Question: What is the "strange" point mentioned in the first sentence? Options: A: The good life is a greater risk than the bad life. B: Starvation is taking more people's lives in the world. C: WHO report shows people's unawareness of food safety. D: Overweight issue remains unresolved despite WHO's efforts.

Read the article and select the best answer. Article: Washoe, a female chimpanzee believed to be the first non-human to acquire human language, has died of natural causes at the research institute where she was kept.The chimp died on Tuesday night, according to Roger and Deborah Fouts, co-founders of The Chimpanzee and Human Communications Institute in Washington, where she lived. Washoe was born in 1965 in Africa, where she was captured by the Air Force and taken to the US for research use in the space program. In 1966, she left the program and began living with two scientists, Allen and Beatrix Gardner, who led a project to teach the chimp American Sign Language (ASL) in Washoe, Nevada, for which it was named. Washoe had been living on Central Washington University's Ellensburg Campus since 1980. She had a vocabulary of about 250 words. Also, Washoe taught sign language to three younger chimps: Tatu, 31, Loulis, 29, and Dar, 31 Primate researcher Jane Goodall, in Fouts' book Next of Kin, noted the importance of the work with Washoe. "Roger, through his ongoing conversations with Washoe and her extended family, has opened a window into a chimpanzee's mind," Goodall said. Though previous efforts to teach chimps spoken languages had failed, the researchers believed there was a better chance using signs. But Washoe's language skills were disputed by scientists who believed that language is unique to humans. Among those who doubted that chimps could use language were linguist Noam Chomsky and Harvard scientist Steven Pinker. They believed primates simply learn to perform certain acts in order to receive rewards, and do not acquire true language. Question: As for its first task, Washoe was involved with _ . Options: A: some space research B: a study on African animals C: an ASL project D: the program of training the Air Force

Read the article and select the best answer. Article: Polluted airborne particles kill 7 million people a year, reports the World Health Organization. That news may not come as a surprise to anyone who has seen images of chimneys in Beijing, Delhi or Mexico. But those factories-or even the jammed roadways of modern cities-are not the biggest killer. Each year, some 4.3 million people die earlier than they should because of polluted air inside their homes, says the WHO. What's causing the air inside people's homes to be so poisonous that it kills around 11,000 people a day? Stoves. "Having an open fire in your kitchen is like burning 400 cigarettes an hour." says Kirk Smith, a professor at the University of California at Berkeley, whose research suggests that household air pollution from cooking killed between 3.5 million and 4 million people in 2013. Not all stoves cause this kind of harm. The ones Smith's talking about are those that the 3 billion people in the developing world use for heat and cooking, which burn solid fuels such as wood, coal, or crop waste instead of gas. The smoke from those fires produces harmful fine particles and carbon monoxide into homes. Poor _ then prevents that smoke from escaping, raising fine particle levels 100 times higher than the limits that the WHO considers acceptable. Breathing this air day in day out eventually causes a lot of diseases: more than a third of the 4.3 million die of a stroke, while a quarter die of heart disease. And around one-third of annual lung disease deaths worldwide are due to waste from coal stoves. Exposure tends to be extremely harmful for the people who spend the most time around the fire-usually women and young children. In fact, the WHO reports that household air pollution almost doubles the risk for childhood lung disease. Question: The author intends to tell people _ . Options: A: how to avoid polluted air in their homes B: to stop cooking in the household kitchen C: to guard against household pollution from cooking D: how to prevent childhood lung diseases in household
