Flying Drones into Danger Zones
A plane is sent deep into the enemy territory with a deadly mission. It is assigned to eliminate several key targets with a precision bombing campaign. This mission won’t be easy, however, as to be successful, the plane will have to avoid enemy rockets and tank fire. There will be no risk to the life of the “pilot” of the plane because he will not be able to aboard the vessel. Instead, he will be thousands of miles away inside a control tower, as he is operating a drone. Drones, which are also called UVAs or unmanned aerial vehicles, marked a major step forward in technology. Inventors have been working on them since the early 1900s. Although some devices were designed back then, they weren’t able to do much more than a standard model airplane. In fact, it was not until a US plane was shot down in 1959 during the Cold War that the US military really got serious about drones. The aim was to save pilots’ lives while flying over hazardous territories. Drones usually fall into two categories. The first type of drones relies on human control from a remote location. The second type of drones is pre­programmed with computer instructions, and it then completes its mission operating autonomously. In addition to protecting pilots’ lives, drones also have several other advantages. They can stay in the air for longer periods of time because there is no concern for eating, sleeping, or rest breaks that pilots typically require. Drones can also be produced cheaper since manufacturers don’t need to value safety precautions as they would for aircraft flown by humans. Despite their usefulness, military drones have been the cause of great criticism over the past decade. There have been cases of British and American drones missing their targets and killing innocent civilians instead. The Brookings Institution released a statistic that for every military leader who is killed by a drone strike, ten civilians die. Some suggest that if human pilots were flying these planes, they wouldn’t have made these errors. Drones don’t always have targets that they must eliminate. The military also employs special surveillance drones that use long-range cameras to gather information about buildings, enemy soldier formations, and other vital information from the ground. In the end, whether people are for or against the use of drones, it appears that they are certain here to stay.

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:
Butterflies are among the most extensively studied insects - an estimated 90 percent of the world's species have scientific names. As a consequence, they are perhaps the best group of insects for examining patterns of terrestrial biotic diversity and distribution. Butterflies also have a favorable image with the general public. Hence, they are an excellent group for communicating information on science and conservation issues such as diversity.
Perhaps the aspect of butterfly diversity that has received the most attention over the past century is the striking difference in species richness between tropical and temperate regions.
For example, in 1875 one biologist pointed out the diversity of butterflies in the Amazon when he mentioned that about 700 species were found within an hour's walk, whereas the total number found on the British islands did not exceed 66, and the whole of Europe supported only 321. This early comparison of tropical and temperate butterfly richness has been well confirmed. A general theory of diversity would have to predict not only this difference between temperate and tropical zones, but also patterns within each region, and how these patterns vary among different animal and plant groups. However, for butterflies, variation of species richness within temperate or tropical regions, rather man between them, is poorly understood. Indeed, comparisons of numbers of species among the Amazon basin, tropical Asia, and Africa are still mostly "personal communication" citations, even for vertebrates, In other words, unlike comparison between temperate and tropical areas, these patterns are still in the documentation phase.
In documenting geographical variation in butterfly diversity, some arbitrary, practical decisions are made. Diversity, number of species, and species richness are used synonymously; little is known about the evenness of butterfly distribution. The New World butterflies make up the preponderance of examples because they are the most familiar species. It is hoped that by focusing on them, the errors generated by imperfect and incomplete taxonomy will be minimized.

Read the following passage and choose the best answer (A, B, C, D):
Carbohydrates, which are sugars, are an essential part of a healthy diet. They provide the main source of energy for the body, and they also function to flavor and sweeten foods. Carbohydrates range from simple sugars like glucose to complex sugars such as amylose and amylopectin. Nutritionists estimate that carbohydrates should make up about one-fourth to one-fifth of a person's diet. This translates to about 75- 100 grams of carbohydrates per day. A diet that is deficient in carbohydrates can have an adverse effect on a person's health. When the body lacks a sufficient amount of carbohydrates it must then use its protein supplies for energy, a process called gluconeogenesis. This, however, results in a lack of necessary protein, and further health difficulties may occur. A lack of carbohydrates can also lead to ketosis, a buildup of ketones in the body that causes fatigue, lethargy, and bad breath.

"The United States has been criticized* for its treatment of its elderly citizens. Although in many other countries the elderly usually live with their children’s family, many older Americans live alone, without the close companionship of their children. This situation is sometimes blamed on the “selfishness” of the younger generation but a closer look shows that many of the elderly prefer to maintain their independent lives.
 Research on the situation of the elderly in America has shown that while grandparents are delighted to be visited periodically by their children and grandchildren, they prefer to continue living in the surroundings that they are familiar with. This suggests that children should permit their parents to live alone if they wish to, and should encourage them to maintain close ties to the rest of the family.
 Another surprising result of the research on the elderly in the United States has been the very positive influence which pets have been found to have on the elderly people that they live with. It has been shown that elderly people who care for small pets, such as cats or dogs, live longer, are healthier, and have better attitudes towards their lives than similar elderly people without these companions."

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:
Niagara Falls, one of the most famous North American natural wonders, has long been a popular tourist destination. Tourists today flock to see the two falls that actually constitute Niagara Falls: the 173-foot-high Horseshoe Falls on the Canadian side of the Niagara River in the Canadian province of Ontario and 182-foot-high American Falls on the U.S. side of the river in the state of New York. Approximately 85 percent of the water that goes over the falls actually goes over Horseshoe Falls, with the rest going over American Falls.
Most visitors come between April and October, and it is quite a popular activity to take a steamer out onto the river and right up to the base of the falls for a close-up view. It is also possible to get a spectacular view of the falls from the strategic locations along the Niagara River, such as Prospect Point of Table Rock, or from one of the four observation towers which have heights up to 500 feet.
Tourists have been visiting Niagara Falls in large numbers since the 1800’s; annual visitation now averages above 10 million visitors per year. Because of concern that all these tourists would inadvertently destroy the natural beauty of this scenic wonder, the State of New York in 1885 created Niagara Falls Park in order to protect the land surrounding American Falls.
A year later Canda created Queen Victoria Park on the Canadian side of the Niagara, around Horseshoe Falls. With the area surrounding the falls under the jurisdiction of government agencies, appropriate steps could be taken to preserve the pristine beauty of the area.
