Without such problems, animals in zoos should live to a ripe old age. But that may not be true for the largest land animals on Earth. Scientists have known that elephants in zoos often develop diseases, joint problems and behavior changes. Sometimes, they even become unable to have babies. To learn more about how captivity affects elephants, a team of international scientists led by Mason, a biologist, compared the life spans of female elephants born in zoos with female elephants living outdoors in the wild. Zoos keep detailed records of all the animals in their care, documenting factors such as birth dates, illnesses, weight and death. These records made it possible for the researchers to analyze 40 years of data on 800 elephants in zoos. The team found that female elephants born in zoos lived an average of 16.9 years. Their wild counterparts who died of natural causes lived an average of 56 years----more than three times as long. Scientists don't yet know for sure why wild elephants seem to live so much better than their zoo-raised counterparts. Mason thinks stress and obesity may be to blame. Zoo elephants don't get the same kind of exercise as they do in the wild, and most are very fat. Elephant social lives are also much different in zoos than in the wild, where they live in large groups. Another finding from the study showed that elephants born in zoos were more likely to die earlier than elephants captured in the wild and brought to zoos. Mason suggests stress in the mothers in zoos might cause them to have babies that are less likely to survive. The study raises some questions about acquiring more elephants to keep in zoos. While some threatened and endangered species living in zoos reproduce successfully and keep healthy populations, that doesn't appear to be the case with elephants. Question: Which of the following can be the best title? - Comparison between two species of elephants - Longer lives for wild elephants - Female elephants suffer from poor health. - Longer lives for zoo animals.
Longer lives for wild elephants

Read the following article and select the best answer. Article: It is 4 o'clock in the early morning. Everything but the computing room on the campus of the university appears as quiet and misty as the mysterious hell. In the computing room, 30 students with sleepy eyes, sit still at their desk, beating the dirty and worn keys. Staring at the colorful screen, they tap continuously for hours. For the other parts in the world, it might be in the middle of the night, nevertheless here time represents nothing. It is an entirely enclosed field. These young computer "hackers" are tracing a sort of stimulus , a drive so exciting and absorbing that it ignores nearly anything else in their lives and becomes the focus of their being. They are addicted computer programmers. Some of these students have been glued to the console for no less than twenty hours even with no break for meals or rest. Some have been sleeping on sofas and chairs in the computing room, trying to struggle for a few moments' rest but hating to get too far away from their addicted machines. It is not necessary for most of these students to be at the computing room in the middle of the night. What they are working belong to no assignments. They remain there because they desire to be -- they can not resist the attraction of the computers. Furthermore, they are in groups instead of being alone. There are hackers at computing rooms all over the country. In the unimaginable way, they focus on nothing but computer. They escape from schooling and live beyond friendship; they might have difficulty being employed, choosing to travel from one computing room to another. They may even give up personal health. "There is one hacker in my memory. We actually had to lift him away from his chair to feed him and arrange him to rest and sleep. We truly worried about his health," says a computing science professor at California University. Professors of computer science are nowadays paying more attention to this hacker phenomenon and are on the watch for future hackers and more and more severe computer addicts. They believe... Question: We can learn from the passage that those at the computing room in the middle of the night are _ . - students working on a program - students using computers to amuse themselves - hard-working computer science majors - students deeply fascinated by the computer
students deeply fascinated by the computer

Q: Read the following article and select the best answer. Article: One day in January, my uncle, my cousin and I decided to go hunting.We left by car in the afternoon.It was a Range Rover with four-wheel drive.It took us three hours to get there.After we arrived at 5:15 p.m., we fixed the tent, then made coffee and had a short rest.After that, we went hunting, using a falcon .We spent two hours without finding anything.On our way back to the camp, my cousin saw a rabbit.I removed the falcon's bead cover and let go of the aggressive falcon.When the rabbit saw the falcon, it ran fast, but my falcon was a professional hunter.He flew up and came down to trick the rabbit.After two minutes, the rabbit was caught.We took it back to the camp to cook our dinner.We ate the delicious food, drank Arabic coffee, and sat around the fire talking until 10:30 p.m. We left the camp the next day at 7 o'clock in the morning.We went north.However, around 10:00 a.m.our car got stuck in the sand! We spent about three hours trying to pull out the car without any progress.Finally, we decided to walk.As it was hard for an old man or a young boy to walk more than 40km in the desert, I decided to get help myself.I took a bottle of water with me and started to walk south alone.I knew the way well, but it was a long way in the sand.I walked more than four hours without stopping.When I felt so tired and thirsty, I stopped to rest.I drank all the water and slept for around two hours. When I got up, it was dark.I continued to walk south.I was worried about my uncle and cousin.Suddenly, I met a Bedouin man who was riding his camel.He took me to his house.When I had had enough rest, I asked him to take me to the road where I found a car.It took me to the city to get help.I had one day to get back to my uncle and cousin.When I got back to them, they were so happy because I had gotten help and they were able to see me again. Question: What can be inferred from the story? - It's an easy job to walk 40km in the desert. - The author loved to go hunting with his family. - The hunting trip is much longer than expected. - To hunt in the desert one must train a falcon well.
A: The hunting trip is much longer than expected.
