Q: I'm taking a test and have to guess the right answer to the question after the article. Article: Nearly all our food comes from the soil. Some of us eat meat, of course, but animals live on plants. If there were no plants, we would have no animals and no meat. So the soil is very necessary for life. The top of the ground is usually covered with grass or other plants. There may be dead leaves and dead plants on the grass. The waste matter from animals also falls on it. All soil needs food. If we do not give it any, the plants will be weak. Farmers found that animals' waste is the best food for the soil, but chemical fertilizers are also very useful. The same crop should not be grown in the same place every year; it's better to have a different crop. A change of crop and the use of a good fertilizer will keep the land good. Question: Why do we often grow a different crop in the same place every year? Options: A: Because we can keep the soil rich this way. B: Because we don't have enough land. C: Because we want to have a different food. D: Because we do this as a habit.
A: A

Q: I'm taking a test and have to guess the right answer to the question after the article. Article: Air pollution by sources ranging from cooking fires to auto fumes contributed to an estimated seven million deaths worldwide in 2012, the UN health agency has said. "Air pollution, and we're talking about both indoors and outdoors, is now the biggest environmental health problem, and _ is affecting everyone, both developed and developing countries," said Maria Neira, the World Health Organisation's public and environmental health chief. Globally, pollution was linked to one death in eight in 2012, new WHO research found. The biggest pollution-related killers were heart disease, stroke, pulmonary disease and lung cancer. The hardest-hit regions of the globe were what the WHO labels Southeast Asia, which includes India and Indonesia, and the Western Pacific, ranging from China and South Korea to Japan and the Philippines. Together, they accounted for 5.9 million deaths. The global death toll included 4.3 million deaths due to indoor air pollution, chiefly caused by cooking over coal, wood and biomass stoves. The toll from outdoor pollution was 3.7 million, with sources ranging from coal heating fires to diesel engines. Many people are exposed to both indoor and outdoor pollution, the WHO said, and due to that overlap the separate death toll attributed to the two sources cannot simply be added together, hence the figure of seven million deaths. The new figure is "shocking and worrying", Ms Neira told reporters. When it last released an estimate for deaths related to air pollution, in 2008, the agency had put the figure related to outdoor pollution at 1.3 million, while the number blamed on indoor pollution was 1.9 million. But a change in research methods makes comparison difficult between the 2008 estimate and the 2012 figures, Neira said. In the past, for example, the WHO did not take into account the overlap between exposure to both forms, and only assessed urban pollution. Satellite imagery has made it easier to assess rural pollution, and new knowledge about the health impact of exposure has enabled a... Question: The death toll in 2008 can hardly compare with that in 2012 because _ . Options: A: the death toll included 4.3 million deaths due to indoor air pollution. B: in 2008 the WHO only assessed rural pollution. C: the research methods changed. D: the risks from air pollution are now far greater than previously thought.
A: C

Q: I'm taking a test and have to guess the right answer to the question after the article. Article: Thousands of years ago, people only ate food that was grown near their homes. Some kinds of food were only grown in one place, so people from other places didn't know about them. When Europeans first traveled to Central and South America in the 1500s, they discovered strange kinds of food that they had never seen before. Today, these are grown in a lot of different countries and they're sold in supermarkets all over the world. They don't seem strange any more! Potatoes were first grown in the Andes in South America. In 1586, they were taken to Europe by explorers . In 1719, they were taken to North America. Before 1719, nobody in North America had ever seen or eaten a potato. Today each American eats more than 60 kilos of potatoes a year. Tomatoes were also first grown by native Americans. When European explorers visited the south of America in 1500, they took tomato seeds back to Europe. Soon, tomatoes were grown in Europe, but people in England didn't eat them. At that time, a lot of English people thought that tomatoes were _ ! Chilies have been eaten in Central and South America for more than 8,000 years!
