Q: Read the following article and select the best answer. Article: Although man has known asbestos for hundreds of years, it was not until 160 years ago that it was mined for the first time on the North American continent. H.W.Johns, owner of a New York City Supply Shop for roofers,was responsible for the opening of that first mine. Mr. Johns was given a piece of asbestos which had been found in Italy. He experimented with the material and then showed its surprising powers to his customers. After putting on a pair of asbestos gloves,which looked much like ordinary work gloves,he took red-hot coals from the fireplace and played with them in his hands. How astonished the customers were to discover that he was not burned at all. You can well imagine that he had increased business in asbestos roofing materials. However,because it was very expensive to transport them from Italy to the United States, Mr. Johns sent out a young scientist to seek a source nearer home. This young man found great vein, in the province of Quebec in Canada. Ever since 1881 Quebec has led the world in the production of this unusual mineral,which is made up of magnesium, silicon, iron, and oxygen. When it is mined, the asbestos is heavy, just as you would expect a mineral to be. When it is separated,a strange thing happens; the rock breaks down into fine, soft, soapy fibers. Scientists do not know why the rock can be separated easily into threads ,but they have found thousands of uses of this fireproof material, of the so- called "cloth of stone." Question: The author's main purpose in writing the passage was to _ . - show the need for more scientists - compare asbestos with other materials - increase the sales of asbestos - present facts about asbestos

Read the following article and select the best answer. Article: In Singapore,most of us love window-shopping while some others enjoy having a picnic at East Coast Park or Changi Beach on sunny days.Singaporeans are never bothered by the occasional thunderstorm.However,we know that if it rains for long continuous periods,there will be more serious effects.Just recently the main shopping street of Orchard Road was flooded and some part of Bukit Timah was impassable to traffic.People reacted by writing in to the newspaper to complain about this! We forget that other countries suffer much worse effects. Elsewhere,heavy tropical storms often result in floods that ruin crops especially in Thailand and Malaysia.This in turn usually means that the price of rice and vegetables here in Singapore will rise because we import these products from them.If there is a typhoon or tsunami,thousands of lives are lost too.This happened in Indonesia and Phuket in Thailand in 2004 and _ serves to remind us of how Mother Nature can cause great damage. Weather patterns in general have changed dramatically in recent years.Scientists believe that global warming and the resulting melting of the polar ice-cap has caused the level of the ocean to rise.This in turn causes flooding of low-lying areas in countries where the land is rather flat and some parts of which is below water level.It is believed that human activities have caused Mother Nature to show her extreme anger,so it is now important that we really work together to cut down on harmful activities,for example,illegal logging or irresponsible forest-burning to clear land for farming. Question: What should we do in order not to make Mother Nature angry? - Clear more land for farming. - Reduce harmful human activities. - Bring down the price of food. - Improve the quality of weather.
