Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions from 13 to 50.           Carbon dating can be used to estimate the age of any organic natural material; it has been used successfully in archeology to determine the age of ancient artifacts or fossils as well as in a variety of other fields. The principle underlying the use of carbon dating is that carbon is a part of all living things on Earth. Since a radioactive substance such as carbon-14 has a known half-life, the amount of carbon-14 remaining in an object can be used to date that object.          Carbon-14 has a half-life of 5,570 years, which means that after that number of years, half of the carbon- 14 atoms have decayed into nitrogen-14. It is the ratio of carbon-14 in that substance that indicates the age of the substance. If, for example, in a particular sample the amount of carbon-14 is roughly equivalent to the amount of nitrogen-14, this indicates that around half of the carbon-14 has decayed into nitrogen-14, and the sample is approximately 5,570 years old.           Carbon dating cannot be used effectively in dating objects that are older than 80,000 years. When objects are that old, much of the carbon-14 has already decayed into nitrogen-14, and the molecule amount that is left doesn’t provide a reliable measurement of age. In the case of older objects, other age-dating methods are available, methods which use radioactive atoms with longer half-lives than carbon hasIt is implied in the passage that______.

Productivity Hacks for Great Success No matter who we are or where we are from, we only have 24 hours each day to get things done. Some people seem to make the most of their time, using it to achieve their goals and dreams. Others feel that life is passing them by and they aren’t accomplishing anything. If you are in the latter group, it is not too late to turn things around. By implementing a few simple hacks, you can start getting better results very quickly.  If you want to become more productive, it pays to learn about the Pareto principle (which is also known as the 80-20 rule). It states that for most tasks, 80 percent of the results we get come from 20 percent of the work we do. For example. 80 percent of the company sales usually come from 20 percent of customers. Therefore, the trick is to focus your efforts on the key 20 percent of actions that truly matter to greatly improve your results.  In some cases, people may be busy from morning to night but still seem to get nothing done. In this situation, the problem might be that clear goals haven’t been set. To fix this, set some time aside to list the things you want to achieve in life. Then, select the top three or four that you want to focus on for the next year. Look at your goals every night before bedtime and ask yourself what are the next actions to accomplish each day. Then, promise yourself that you will finish these tasks no matter how busy you get. If possible try completing the tasks first thing in the morning so you are assured of success.   Another common mistake regarding productivity is not considering our energy levels. If we try to work around the clock, we will eventually get tired and quit. Everyone needs time to sleep, eat, socialize with friends, and unwind from the stress of the day. To make sure you don’t burn out, be sure to schedule some time for breaks and fun activities into your schedule every day. Finally, no matter how difficult your goals may seem, remember the old saying that “a journey of a thousand miles begins with a single step”Which of the following sentences is true?

Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questionsTRACKING THE SNOW LEOPARD“When a snow leopard stalks its prey among the mountain walls, it moves softly, slowly,” explains Indian biologist Raghunandan Singh Chundawat, who has studied the animal for years. “If it knocks a stone loose, it will reach out a foot to stop it from falling and making noise.” One might be moving right now, perfectly silent, maybe close by. But where? And how many are left to see?Best known for its spotted coat and long distinctive tail, the snow leopard is one of the world’s most secretive animals. These elusive cats can only be found high in the remote, mountainous regions of central Asia. For this reason, and because they hunt primarily at night, they are very rarely seen.Snow leopards have been officially protected since 1975, but enforcing this law has proven difficult. Many continue to be killed for their fur and body parts, which are worth a fortune on the black market. In recent years, though, conflict with local herders has also led to a number of snow leopard deaths. This is because the big cats kill the herders’ animals, and drag the bodies away to eat high up in the mountains.As a result of these pressures, the current snow leopard population is estimated at only 4,000 to 7,000, and some fear that the actual number may already have dropped below 3,500. The only way to reverse this trend and bring these cats back from near extinction, say conservationists, is to make them more valuable alive than dead.Because farming is difficult in Central Asia’s cold, dry landscape, traditional cultures depend mostly on livestock (mainly sheep and goats) to survive in these mountainous regions. At night, when snow leopards hunt, herders’ animals are in danger of snow leopard attacks. Losing only a few animals can push a family into desperate poverty. “The wolf comes and kills, eats, and goes somewhere else,” said one herder, “but snow leopards are always around. They have killed one or two animals many time. Everybody wanted to finish this leopard.”To address this problem, local religious leaders have called for an end to snow leopard killings, saying that these wild animals have the right to exist peacefully. They’ve also tried to convince people that the leopards are quite rare and thus it is important to protect them. Financial incentives are also helping to slow snow leopard killings. The organization Snow Leopard Conservancy–India has established Himalayan Homestays, a program that sends visitors to the region to herders’ houses. For a clean room and bed, meals with the family, and an introduction to their culture, visitors pay about ten U.S. dollars a night. Having guests once every two weeks through the tourist season provides the herders with enough income to replace the animals lost to snow leopards. In addition, Homestays helps herders build protective fences that keep out snow leopards. The organization also conducts environmental classes at village schools and trains Homestays members as nature guides, available for hire. In exchange, the herders agree not to kill snow leopards.In Mongolia, a project called Snow Leopard Enterprises (SLE) helps herder communities earn extra money in exchange for their promise to protect the endangered cat. Women in Mongolian herder communities make a variety of products—yarn for making clothes, decorative floor rugs, and toys—using the wool from their herds. SLE buys these items from herding families and sells them abroad. Herders must agree to protect the snow leopards and to encourage neighbors to do the same.The arrangement increases herders’ incomes by 10 to 15 percent and “elevates” the status of the women. If no one in the community kills the protected animals over the course of a year, the program members are rewarded with a 20 percent bonus in addition to the money they’ve already made. An independent review in 2006 found no snow leopard killings in areas where SLE operates. Today the organization continues to add more communities. Projects like the Homestays program in India and SLE’s business in Mongolia are doing well, though they cover only a small part of the snow leopard’s homeland, they make the leopards more valuable to more people each year.

Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questionsTRACKING THE SNOW LEOPARD“When a snow leopard stalks its prey among the mountain walls, it moves softly, slowly,” explains Indian biologist Raghunandan Singh Chundawat, who has studied the animal for years. “If it knocks a stone loose, it will reach out a foot to stop it from falling and making noise.” One might be moving right now, perfectly silent, maybe close by. But where? And how many are left to see?Best known for its spotted coat and long distinctive tail, the snow leopard is one of the world’s most secretive animals. These elusive cats can only be found high in the remote, mountainous regions of central Asia. For this reason, and because they hunt primarily at night, they are very rarely seen.Snow leopards have been officially protected since 1975, but enforcing this law has proven difficult. Many continue to be killed for their fur and body parts, which are worth a fortune on the black market. In recent years, though, conflict with local herders has also led to a number of snow leopard deaths. This is because the big cats kill the herders’ animals, and drag the bodies away to eat high up in the mountains.As a result of these pressures, the current snow leopard population is estimated at only 4,000 to 7,000, and some fear that the actual number may already have dropped below 3,500. The only way to reverse this trend and bring these cats back from near extinction, say conservationists, is to make them more valuable alive than dead.Because farming is difficult in Central Asia’s cold, dry landscape, traditional cultures depend mostly on livestock (mainly sheep and goats) to survive in these mountainous regions. At night, when snow leopards hunt, herders’ animals are in danger of snow leopard attacks. Losing only a few animals can push a family into desperate poverty. “The wolf comes and kills, eats, and goes somewhere else,” said one herder, “but snow leopards are always around. They have killed one or two animals many time. Everybody wanted to finish this leopard.”To address this problem, local religious leaders have called for an end to snow leopard killings, saying that these wild animals have the right to exist peacefully. They’ve also tried to convince people that the leopards are quite rare and thus it is important to protect them. Financial incentives are also helping to slow snow leopard killings. The organization Snow Leopard Conservancy–India has established Himalayan Homestays, a program that sends visitors to the region to herders’ houses. For a clean room and bed, meals with the family, and an introduction to their culture, visitors pay about ten U.S. dollars a night. Having guests once every two weeks through the tourist season provides the herders with enough income to replace the animals lost to snow leopards. In addition, Homestays helps herders build protective fences that keep out snow leopards. The organization also conducts environmental classes at village schools and trains Homestays members as nature guides, available for hire. In exchange, the herders agree not to kill snow leopards.In Mongolia, a project called Snow Leopard Enterprises (SLE) helps herder communities earn extra money in exchange for their promise to protect the endangered cat. Women in Mongolian herder communities make a variety of products—yarn for making clothes, decorative floor rugs, and toys—using the wool from their herds. SLE buys these items from herding families and sells them abroad. Herders must agree to protect the snow leopards and to encourage neighbors to do the same.The arrangement increases herders’ incomes by 10 to 15 percent and “elevates” the status of the women. If no one in the community kills the protected animals over the course of a year, the program members are rewarded with a 20 percent bonus in addition to the money they’ve already made. An independent review in 2006 found no snow leopard killings in areas where SLE operates. Today the organization continues to add more communities. Projects like the Homestays program in India and SLE’s business in Mongolia are doing well, though they cover only a small part of the snow leopard’s homeland, they make the leopards more valuable to more people each year. If these programs continue to do well, the snow leopard may just have a figting chance.According to conservationists, what is the best way to save the snow leopard?
