Article: Visiting animals in their natural homes may sound like a great idea that helps to save them, but is it ? Researchers writing in Trends in Ecology & Evolution on Oct9 said that the interactions between wild animals and friendly eco-tourists who want to take their pictures may put animals at greater risk of being eaten. It is clear that many people visit protected areas every year. "Recent data showed that protected areas around the globe have 8 billion visitors per year; that's like each human on Earth visited a protected area once a year, and then some!"said Dainel Blumstein of the University of California, Los Anglels. "This amount of nature tourism and eco-tourism can be added to the long list of ways in which humans cause fast environmental change. The basic idea of the report the report is that humans change the ways animals act and those changes might affect other parts of their lives, according to Science Daily. Those changes in behavior and activity may put animals at risk. "When animals spend time in 'harmless' ways with humans, they may let down their guard," Blumstein said. As animals get used to feeling comfortable with humans, they may become braver in other situations, he says . "If this bravery continues when they meet real predators , then they will die more often when they meet them." Eco-tourism is in some ways similar to making animals live in human homes or in cities. In all three cases, regular interactions between people and animals tame. Evidence has shown that silver foxes that live with people become more laid-back and less fearful; this results from evolutionary changes but also from spending time with humans. Simply put , as Blumstein asked in the Scientific American magazine:"Does eco-tourism make animals _ ?" And that's not all - humans can also scare away natural predators , creating the so-called "human shield effect" and a safe environment for smaller animals that might make them braver, too. When humans are around, for example, vervet monkeys don't see as many leopards trying... Question: We can infer that the writer wrote this passage mainly to _ . Yes or no, is the answer "Wildlife tourism may seem helpful, but it can be deadly for some animals"?

Article: A new American report says water-related problems will likely increase tensions around the world in the next ten years. These problems include water shortages, poor water quality and floods. The problems will increase the risk of failure of governments. However, countries are unlikely to go to war over water. But the real question is that some governments may use water as a weapon to pressure others ten years later. The report looks at possible effects of water problems on the United States national security interests over the next thirty years. It says the areas that will be most affected by water problems are North Africa, the Middle East and South Asia. The United States Secretary of State Hillary Clinton says, "Reliable water resources are essential for feeding the hungry, running industries and creating energy. Certainly they are central when we think about how climate changes will affect future generations." The report also predicts an increased demand for American assistance and expert help to solve those problems. That demand for help could create opportunities for leadership and influence. Water shortages, poor water quality, and floods are unlikely to result in state failure. But these could combine with poverty, social tensions, environmental problems, poor leadership and weak governments to produce social disorder. And that combination could cause state failure. The report predicts that from now through 2040 water shortages and pollution probably will harm the economic performance of important trading partners. During the next ten years the loss of groundwater supplies in some agricultural areas will create a risk to national and global food markets. These shortages will be a result of poor management. Agriculture uses about seventy percent of the world's freshwater. The report says technology that reduces the amount of water needed to grow crops will offer the best way to fight against water shortages. Question: This article mainly talks about _ . Yes or no, is the answer "effects of water problems around the world"?

No

Article: Upon reaching an appropriate age (usually between 18 and 21 years), children are encouraged, but not forced, to "leave the nest" and begin an independent life. After children leave home, they often find social relationship and financial support outside the family. Parents do not arrange marriages for their children, nor do children usually ask permission of their parents to get married. Romantic love is most often the basis for marriage in the United States; young adults meet their future spouses through other friends, at jobs, and in organizations and religious institutions. Although children choose their own spouses, they still hope their parents will approve of their choices. In many families, parents feel that children should make major life decisions by themselves. A parent may try to influence a child to follow a particular profession but the child is free to choose another career. Sometimes children do exactly the opposite of what their parents wish in order to be independent. A son may decide not to go into his father's business on purpose because of a fear that he will lose his autonomy in his father's workplace. This independence from parents is not an indication that parents and children do not love each other. Strong love between parents and children is universal and this is no exception in the American family. Coexisting with such love in the American family are cultural values of self-reliance and independence. Question: The writer discusses the marriage of young adults in order to show which of the following? Yes or no, is the answer "They have independence."?
**Answer**
No
