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 28 to 35. In America, when dining, people consider it rude for a guest or dining partner to belch or burp, eat with an open mouth, smack, or lick your fingers. Napkins, generally provided are available at every meal and should be placed in one's lap and then used throughout the meal to clean one's fingers and mouth. It is acceptable to refuse additional servings of food by saying "No, thank you" and the host or hostess will not be insulted if you do so. Similarly, if you leave a small amount of uneaten food on your plate at a restaurant or in a home, it is not considered an insult. If you eat everything on the plate, a host or hostess may possibly feel that they have not prepared enough food and might be embarrassed. People in the United States serve and eat food with either hand, but never take food from a communal serving dish with their hands. Generally, a serving utensil is used. Americans typically use forks, spoons and knives to eat, but there are some types of foods that are acceptable to eat with one's fingers, like sandwiches or pizza. When in doubt, look to see what others are doing. In formal dining situations, if you wonder whether or not it is acceptable to begin eating, you should wait until the oldest woman (or oldest man if no women are present) begins to eat. When eating, do not pick up the bowl or plate from the table to hold underneath your mouth, Even noodles, soup, and rice are eaten with the plate or bowl remaining on the table. When consuming soup and hot liquids, it is considered impolite to slurp - do not do this. When consuming noodles, twirl them around your fork and then put it in your mouth. If you are a man taking out a woman for dinner, you are almost always expected to pay. This is for the woman to gauge your intentions and interest with her. For example, taking a woman for coffee, versus tacos, versus a fancy dinner, versus for drinks at 11:30pm, all signal many different things to them. So, the date is a -test- of many. Paying is just as important as where you take her, and how late. So, don't assume she is just trying to get a "free meal". Most girls aren't. Also, if you are going out with a friend to eat, almost always, the bill is expected to be split in half, or each person pays for themselves. If you are eating in a restaurant, you will be expected to add a 15 to 20 % tip for the server to your bill. In America, wait staff might occasionally stop by your table to ask how your meal is, which is considered good service. They will also bring you your check when it seems reasonable that you are finished with your meal, however this is not necessarily an indication that you must leave right away (Do not be too embarrassed to ask for the check either waiters and waitresses cannot read minds.) Take your time to finish your meal, and unless there is a line of people waiting at the door, it is not considered rude to linger at your table for as long as you like. Question 28: Which of the following could be the best title of the passage?

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 35 to 42. Most desert animals will drink water if confronted with it, but many of them never have any opportunity. All living things must have water, or they will expire. The herbivores find it in desert plants. The carnivores slake their thirst with the flesh and blood of living prey. One of the most remarkable adjustments, however, has been made by the tiny kangaroo rat, who not only lives without drinking but subsists on a diet of dry seeds containing about 5% free water. Like other animals, he has the ability to manufacture water in his body by a metabolic conversion of carbohydrates. But he is notable for the parsimony with which he conserves his small supply by every possible means, expending only minuscule amounts in his excreta and through evaporation from his respiratory tract. Investigation into how the kangaroo rat can live without drinking water has involved various experiments with these small animals. Could kangaroo rats somehow store water in their bodies and slowly utilize these resources in the long periods when no free water is available from dew or rain? The simplest way to settle this question was to determine the total water content in the animals to see if it decreases as they are kept for long periods on a dry diet. If they slowly use up their water, the body should become increasingly dehydrated, and if they begin with a store of water, this should be evident from an initial high water content. Results of such experiments with kangaroo rats on dry diets for more than 7 weeks showed that the rats maintained their body weight. There was no trend toward a decrease in water content during the long period of water deprivation. When the kangaroo rats were given free access to water, they did not drink water. They did nibble on small pieces of watermelon, but this did not change appreciably the water itent in their bodies, which remained at 66.3 % to 67.2 % during this period. This is very close to the water content of dry-fed animals (66.5 %), and the availability of free water, therefore, did not lead to any “storage” that could be meaningful as a water reserve. This makes it reasonable to conclude that physiological storage of water is not a factor in the kangaroo rat’s ability to live on dry food. According to the passage, the results of the experiments with kangaroo rats showed that

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. Today's cars are smaller, safer, cleaner, and more economical than their predecessors, but the car of the future will be far more pollution-free than those on the road today. Several new types of automobile engines have already been developed that run on alternative sources of power, such as electricity, compressed natural gas, methanol, steam, hydrogen, and propane. Electricity, however, is the only zero- emission option presently available. Although electric vehicles will not be truly practical until a powerful, compact battery or other dependable source of current is available, transportation experts foresee a new assortment of electric vehicles entering everyday life: shorter-range commuter electric cars, three-wheeled neighborhood cars, electric delivery vans, bikes, and trolleys. As automakers work to develop practical electrical vehicles, urban planners and utility engineers are focusing on infrastructure systems to support and make the best use of the new cars. Public charging facilities will need to be as common as today's gas stations. Public parking spots on the street or in commercial lots will need to be equipped with devices that allow drivers to charge their batteries while they stop, dine, or attend a concert. To encourage the use of electric vehicles, the most convenient parking in transportation centers might be reserved for electric cars. Planners foresee electric shuttle buses, trains, buses, and neighborhood vehicles all meeting at transit centers that would have facilities for charging and renting. Commuters will be able to rent a variety of electric cars to suit their needs: light trucks, one-person three-wheelers, small cars, or electric/gasoline hybrid cars for longer trips, which will no doubt take place on automated freeways capable of handling five times the number of vehicles that can be carried by a freeway today. The word “commuters” in paragraph 4 refers to ____________.

This makes it reasonable to conclude that physiological storage of water is not a factor in the kangaroo rat’s ability to live on dry food. Which of the following is NOT a source of water for the desert animals?

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 35 to 42. Most desert animals will drink water if confronted with it, but many of them never have any opportunity. All living things must have water, or they will expire. The herbivores find it in desert plants. The carnivores slake their thirst with the flesh and blood of living prey. One of the most remarkable adjustments, however, has been made by the tiny kangaroo rat, who not only lives without drinking but subsists on a diet of dry seeds containing about 5% free water. Like other animals, he has the ability to manufacture water in his body by a metabolic conversion of carbohydrates. But he is notable for the parsimony with which he conserves his small supply by every possible means, expending only minuscule amounts in his excreta and through evaporation from his respiratory tract. Investigation into how the kangaroo rat can live without drinking water has involved various experiments with these small animals. Could kangaroo rats somehow store water in their bodies and slowly utilize these resources in the long periods when no free water is available from dew or rain? The simplest way to settle this question was to determine the total water content in the animals to see if it decreases as they are kept for long periods on a dry diet. If they slowly use up their water, the body should become increasingly dehydrated, and if they begin with a store of water, this should be evident from an initial high water content. Results of such experiments with kangaroo rats on dry diets for more than 7 weeks showed that the rats maintained their body weight. There was no trend toward a decrease in water content during the long period of water deprivation. When the kangaroo rats were given free access to water, they did not drink water. They did nibble on small pieces of watermelon, but this did not change appreciably the water itent in their bodies, which remained at 66.3 % to 67.2 % during this period. This is very close to the water content of dry-fed animals (66.5 %), and the availability of free water, therefore, did not lead to any “storage” that could be meaningful as a water reserve. This makes it reasonable to conclude that physiological storage of water is not a factor in the kangaroo rat’s ability to live on dry food. The word “expire” in paragraph 2 is closest in meaning to _________.

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 28 to 34. The main difference between urban growth in Europe and in the American colonies was the slow evolution of cities in the former and their rapid growth in the latter. In Europe they grew over a period of centuries from town economies to their present urban structure. In North America, they started as wilderness communities and developed to mature urbanism’s in little more than a century. In the early colonial day in North America, small cities sprang up along the Atlantic Coastline, mostly in what are now New America, small cities sprang up along the Atlantic United States and in the lower Saint Lawrence valley in Canada. This was natural because these areas were nearest England and France, particularly England, from which most capital goods (assets such as equipment) and many consumer goods were imported Merchandising establishments were, accordingly, advantageously located in port cities from which goods could be readily distributed to interior settlements. Here, too, were the favored locations for processing raw materials prior to export. Boston, Philadelphia, New York, Montreal, and other cities flourished, and, as the colonies grew, these cities increased in importance. This was less true in the colonial South, where life centered around large farms, known as plantations, rather than around towns, as was the case in the areas further north along the Atlantic coastline. The local isolation and the economic self-sufficiency of the plantations were antagonistic to the development of the towns. The plantations maintained their independence because they were located on navigable streams and each had a wharf accessible to the small shipping of that day. In fact, one of the strongest factors in the selection of plantation land was the desire to have it front on a water highway. When the United States became an independent nation in 1776, it did not have a single city as large as 50,000 inhabitants, but by 1820 it had a city of more than 10,000 people, and by 1880 it had recorded a city of over one million. It was not until after 1823, after the mechanization of the spinning and weaving industries, that cities started drawing young people away from farms. Such migration was particularly rapid following the Civil War (1861-1865). The word “drawing” in the last paragraph is closest in meaning to _________.

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. Today's cars are smaller, safer, cleaner, and more economical than their predecessors, but the car of the future will be far more pollution-free than those on the road today. Several new types of automobile engines have already been developed that run on alternative sources of power, such as electricity, compressed natural gas, methanol, steam, hydrogen, and propane. Electricity, however, is the only zero- emission option presently available. Although electric vehicles will not be truly practical until a powerful, compact battery or other dependable source of current is available, transportation experts foresee a new assortment of electric vehicles entering everyday life: shorter-range commuter electric cars, three-wheeled neighborhood cars, electric delivery vans, bikes, and trolleys. As automakers work to develop practical electrical vehicles, urban planners and utility engineers are focusing on infrastructure systems to support and make the best use of the new cars. Public charging facilities will need to be as common as today's gas stations. Public parking spots on the street or in commercial lots will need to be equipped with devices that allow drivers to charge their batteries while they stop, dine, or attend a concert. To encourage the use of electric vehicles, the most convenient parking in transportation centers might be reserved for electric cars. Planners foresee electric shuttle buses, trains, buses, and neighborhood vehicles all meeting at transit centers that would have facilities for charging and renting. Commuters will be able to rent a variety of electric cars to suit their needs: light trucks, one-person three-wheelers, small cars, or electric/gasoline hybrid cars for longer trips, which will no doubt take place on automated freeways capable of handling five times the number of vehicles that can be carried by a freeway today. The word “foresee” in this passage could best be replaced with __________.
