Ques: Read the following article and select the best answer. Article: Scientists at Harvard University and Bates College find female chimpanzees appear to treat sticks as dolls, carrying them around until they have children of their own. Young males engage in such behavior much less frequently. The new work by Sonya M. Kahlenberg and Richard W. Wrangham, described this week in the journal Current Biology, provides the first evidence of a wild nonhuman species playing with dolls, as well as the first known sex difference in a wild animal's choice of playthings. The two researchers say their work adds to a growing body of evidence that human children are probably born with their own ideas of how they want to behave, rather than simply mirroring other girls who play with dolls and boys who play with trucks. Doll play among humans could have its origins in object--carrying by earlier apes , they say, suggesting that toy selection is probably not due entirely to socialization. "In humans, there are obvious sex differences in children's toy play, and these are remarkably similar across cultures," says Kahlenberg. "While socialization by elders and peers has been the primary explanation, our work suggests that biology may also have an important role to play in activity preferences." In 14 years of data on chimpanzee behavior at the Kibale National Park in Uganda, Kahlenberg and Wrangham counted more than 100 examples of stickcarrying. Some young chimpanzees carried sticks into the nest to sleep with them and on one occasion built a separate nest for the stick. "We have seen juveniles occasionally carrying sticks for many years, and because they sometimes treated them rather like dolls, we wanted to know if in general this behavior tended to represent something like playing with dolls," says Wrangham, a Professor at Harvard. "If the doll hypothesis was right, we thought that females should carry sticks more than males do, and that the chimpanzees should stop carrying sticks when they had their first child. We have now watched enough young chimpanzees to prove both points." Question: It can be concluded from the passage that _ . - both humans and chimpanzees choose their playthings due to sex difference - different factors cause humans and chimpanzees to choose different playthings - only female chimpanzees have playthings - chimpanzees usually choose playthings for their children
Ans: both humans and chimpanzees choose their playthings due to sex difference

Ques: Read the following article and select the best answer. Article: The largest known outbreak of the lethal Ebola virus in West Africa is prompting authorities as far away as Asia to take preventive measures, although scientists say a global spread of the disease is unlikely. At South Korea's Incheon International airport, a major hub for air travel in Asia, quarantine inspections of arriving passengers are being enhanced. Authorities say all passengers are being recorded by an infrared camera to detect fevers because Ebola is becoming a big concern. The incubation period of the Ebola virus is between two and 21 days, during which time an infected person might not show any signs of infection. In Hong Kong, the Center for Health Protection says public hospitals will begin to report and test all those who developed fever who, within the past 21 days, traveled to the three affected African countries. Singapore's health ministry is urging the public there "not to be alarmed." It has issued a statement deeming Ebola to pose "a low public health risk to Singapore," in part because "there is low travel connectivity to West Africa where the current outbreak remains limited to." Some airlines have suspended flights into the affected region. But health authorities say there is little risk of passengers contracting the virus on a flight from an infected person.Dr. Day, a tropical medicine researcher, explains Ebola is only spread through direct contact with blood, saliva and other bodily fluids. Since March, there have been more than 1,200 confirmed Ebola cases in West Africa. This is believed to be a new strain of the virus and nearly 700 of those infected in this worst-known outbreak have died.There is no known cure for Ebola. It was first recognized in Zaire (now the Democratic Republic of Congo) in 1976. There is no approved vaccine, but at least four are under development. Question: The passage may come from _ . - a school magazine - a travel booklet - a newspaper - a textbook
Ans: a newspaper

Ques: Read the following article and select the best answer. Article: One Sunday a few of us decided to take advantage of the first sunny day we'd have for ages to take a trip down to the coast to visit the penguins again. Last time I went down there was a couple of months ago and it was a dull cold day. Sunday couldn't have been more different -- clear skies and sunshine made it feel like summer, although it was still -25degC. Six of us drove to the coast. It was the first time we'd been off the base on our own without our field assistant, so it had a slightly different feeling -- more like a few friends going to the seaside than an Antarctic field trip! When we reached Windy Creek, we luckily caught sight of quite a few small flying seabirds, which are seldom seen there. Once on the sea ice we found that some of the more curious penguins had wandered over from the main group to come and check us out. We'd been told that then they were nursing their chicks and they would be more careful and nervous than last time, We walked across to the main group which were stretched for a couple of miles along the coast. We sat down for some sandwiches and soon found ourselves surrounded by many curious observers. Without any attackers on land, they were very brave and came within a meter of us to pose for photos. Before heading back, we spent a few hours on the sea ice watching the penguins and their chicks, which had grown dramatically since our last visit. It was such a nice day. Question: What does the writer mean by saying "but that didn't seem to be the case"? - They were told a lie. - A wrong decision was made. - The truth was the opposite. - They didn't believe what they were told.
Ans: The truth was the opposite.

Ques: Read the following article and select the best answer. Article: Martha was busy with her job. She believed she had to work harder because she loved her father who was sick with cancer. She had to provide for his expensive medicines. Her brothers and sisters meanwhile stayed with their father most of the time. They bathed him, sang for him, spoon-fed him or simply kept him company. One day Martha was hurt. She overheard her father telling her mother, "All our children love me except Martha." "How can this be?" Martha thought. "Am I not the one killing myself in my work to have money to pay for his medicines? My brothers and sisters do not even provide their share in the expenses." One night, as Martha was as usual late in going home, she saw her father was lying awake. She walked close to his bedsides. Her father held her hands and said, "I miss you. I don't have much time. Stay with me." And she stayed with her father holding his hand the whole night. The next morning Martha said to everybody, "I have taken a leave of absence. I would like to be with father. I will bathe him and sing for him from now on." Her father had a beautiful smile. He knew Martha loved him, too. As children, we need the presence of our loved ones. Adults need no less. I have observed my mother's orchids . When she is away for a long time, they are unhealthy and many of them wither . But when she is around , they bloom with beautiful flowers. My mother does nothing special . She just spends her time looking after them. Question: By telling Matha's story, what does the author try to express? - Nothing is more important than the company of loved ones. - Money and a successful career don't always bring happiness - Adults need the presence of their loved ones more than children do. - Plants like orchids do have feelings.
Ans:
Nothing is more important than the company of loved ones.
