Question: Plants need green leaves to make food. A plant needs sunlight and carbon dioxide  from the air for making food and it also needs water and salts from the soil to make food too. There are certain cells   in the leaves which change carbon dioxide and water into sugar. To do this the cells needs energy, which they get from the sunlight. Green leaves make food for the whole plant. A red leaf can make food too because under the red color1ing of the leaf there are food----making cells. There are no leaves which are completely yellow, for they can't make food. The plant makes sugar for its food. In sunlight green leaves make a lot of sugar. The veins   can't carry all this sugar away, so the leaves change the sugar into starch  , which is kept and so stored in the leaves. At night, the starch changes back to sugar. It is then carried away from the leaves. Some of the sugar is used as food by the plant while the rest is stored as starch. In some plants, food is stored in the roots, in others it is stored in the stem   and in leaves, fruits and seeds. Which of the following best gives the main idea of this passage?   _  . A) How green plants make food. B) How green plants make sugar. C) How green plants get their energy. D) How green plants change sugar into starch.

Question: Consumers are being confused and misled by the hodge-podge  of environmental claims made by household products, according to a "green labeling" study published by Consumers International Friday. Among the report's more unacceptalbe findings - a German fertilizer described itself as "earthworm friendly"; a brand of flour said it was "non-polluting" and a British toilet paper claimed to be "environmentally friendlier". The study was written and researched by Britain's National Consumer Council (NCC) for lobby group Consumers International. It was funded by the German and Dutch governments and the European Commission. "While many good and useful claims are being made, it is clear that there is a long way to go in ensuring shoppers are adequately informed about the environmental impacts they buy," said Consumers International director, Anna Fielder. The 10-country study surveyed product packaging in Britain, Western Europe, Scandinavia and the United States. It found that products sold in Germany and the United Kingdom made the most environmental claims on average. The report focused on claims made by specific products, such as detergent  , insect sprays and some garden products. It did not test claims, but compared them to labeling guidelines set by the International Standards Organization (ISO) in September, 1999. Researchers documented claims of environmental friendliness made by about 2,000 products and found many too vague or too misleading to meet ISO standards. "Many products had specially designed labels to make them seem environmentally friendly, but in fact many of these symbols mean nothing," said report researcher Philip Page. "Laundry detergents made the most number of claims with 158. Household cleaners were second with 145 separate claims, while paints were third on our list with 73. The high numbers show how confusing it must be for consumers to sort the true from the misleading," he said. The ISO labeling standards ban vague or misleading claims on product packaging, because terms such as... It can be inferred from the passage that the lobby group Consumer International wants to   _  . A) make product labeling satisfy ISO requirements B) see all household products meet environmental standards C) warn consumers of the danger of so-called green products D) verify the effects of non-polluting products
