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 _ .

Read the article and select the best answer. Article: Warm water freezes more quickly than cold water. Sir Francis Bacon said that almost four hundred years ago. But few people believed him until 1970. In that year Canadian scientist Geoge Kell proved the English physicist was right. Dr Kell filled one open bowl with cold water. He filled another with warm water. He put both bowls to the same low temperature. The warm water froze first. The lack of covers on the bowls was the secret . Some of the warm water changed into vapor. It evaporated into the air. This meant that less of the warm water was left to freeze. And so the warm water froze faster than the cold water. Question: Sir Francis Bacon was _ . Options: A: an American scientist B: a Canadian scientist C: a French scientist D: an English scientist
**Answer**
D

Jack Gleeson,17,a high school student working a summer job at the airport,caught up to Schum and,with Bochter's help, 1ifted the chain-link fence and brought Brillo underneath it.Moments later,the entire plane exploded. After the rescue team arrived,Bochter and Brillo were airlifted to a nearby hospital and treated for cuts,injuries and Brillo's broken arm, Bochter, an experienced pilot, 1ater said that the plane's electrical system had failed shortly after takeoff.He had been attempting to land at the East Hampton Airport when the plane began to nosedive.He managed to level the wings before crashing into the woods.

Read the article and select the best answer. 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: Most young adults in the U.S. get married because of _ . Options: A: their parents B: financial concern C: love D: family background
