Ques:Read the article and select the best answer. Article: Solar   water heaters can use energy from the sun to heat water. They are used around the world. The solar water heater is based on a design developed some years ago in Afghanistan. Since then, it has been built and used in many countries. It can heat seventy liters   of water to 60degC. It can do this between sunrise and noon on a clear day with an average temperature of 32degC. There are two parts of the solar water heater. One part, the collector, is made of a metal plate painted black. This metal surface, placed in contact with the water, will heat the water. Black-painted surfaces that receive the sun's heat become hotter than those of any other color1. Metal plates that have raised parts on the surface work better than those without them. Once the water is heated, it is kept hot with special material, which allows the water to stay warm for a long time. The second part of the solar water heater holds the water for the system. This water tank   can hold about one hundred liters of water. Two rubber pipes are connected to the water tank. One pipe lets water go into the system. The other lets water go out. When the water heater is working correctly, water will flow from the tank to the collector and back again. You can use the hot water at the top of the tank for washing and cleaning. This solar water heater is easy to build and operate. It will last about two years before the rubber pipes need to be replaced. Question: The color1 of the collector is black because   _  . Options: A: it is the cheapest color1 paint B: it can be found easily in daily life C: it can take in more energy than other color1s D: it is good for protecting the metal surface

Ans:C

Ques:Read the article and select the best answer. Article: The World Bank is warning that the West Africa Ebola outbreak could seriously harm the economies  of Guinea, Liberia and Sierra Leone unless action is taken quickly. World Bank President Jim Yong Kim spoke to reporters recently to discuss the effects of the Ebola spread. "Our findings show that if the virus  continues to spread, the economic cost to these countries could grow eight times by 2015. This would be a big _ to their already weak economies," said Kim. Mr. Kim says, "saving lives and preventing new spread" is most important. The bank has given $117-million for an "immediate help." The World Bank President says the SARS outbreak between 2002 and 2004 showed how a disease could damage economies. 800 people died from SARS and the economic losses were up to $40-billion. Mr. Kim says SARS and the H1N1 outbreak of 2009 taught that fear and avoidance resulted in about 90-percent of the economic losses. That means the disease is causing two levels of economic damage. "There are two kinds of contagion . One is connected with the virus itself and the second is connected with the spread of fear about the virus," said Kim. The World Bank thinks the losses to the economies of Liberia, Sierra Leone and Guinea will be big .Mr. Kim says losses could be about $97-million at the moment. Mr. Kim says fast action is necessary. He says getting the disease under control is still far away. That is because there are not enough health care workers in the affected areas. The World Bank President says the most important measure is to act quickly in order to limit economic losses. Question: What's the main idea of the whole passage? Options: A: Ebola is a serious and infectious illness. B: Large numbers of people have died from Ebola. C: People in the West Africa are in great fear of the spread of Ebola virus.
