  • Vocational General Knowledge (0890) Answers 1. The correct answer is C. In the social sciences, socialization 9. The correct answer is D. In sampling, the assumption is that is defined as the process by which an individual learns the rules the behavior of the sample mirrors the behavior of the total of expected behavior in a society. population. Thus, in this case, the ratio of the number of families in the sample that were watching the program is equal to the 2. The correct answer is A. Egypt is in the northeastern part of ratio of the number of families in the total population with the continent of Africa, which is pictured in Map 1. Map 2 depicts television sets that were watching. Therefore, 200/1,500 or 2/15 South America and most of North America. Map 3 depicts = n/64,000,000. Solving the proportion, 15n = (64,000,000)(2), so Central and East Asia as well as Australia. Map 4 shows the n = 128,000,000/15, which is approximately 8,500,000 families. continent of Antarctica. 10. Choice A is the correct answer. Since the entire rectangular 3. The correct answer is A. Inflation is an economic condition region in Figure I is used in Figure II, the area of Figure II must be characterized by a general rise in prices throughout an economy. equal to the area of Figure I. The area of Figure I is easily In periods of high inflation, the same amount of money buys far calculated as the length (2+2+1) times the height (3) = 15 square fewer goods; therefore consumer buying power, in general, units. decreases. 11. This question requires you to apply the given definition of 4. The correct answer is C. Roosevelt’s New Deal established range. According to the table, the lowest record low temperature, a wide range of new federal agencies concerned with issues in degrees Fahrenheit, is 31 and the highest record low including financial regulation of the economy, social welfare, and temperature is 39. Using the definition given, subtract 31 from economic development, thereby expanding the size, scope, and 39: 39  ( 31)  70 . Thus, the range is 70 degrees. The responsibility of the national government. Banks were not correct answer is D. nationalized, the size of the Supreme Court did not expand, and decisions about welfare spending were concentrated in the 12. The minimum length of wallpaper border needed to federal government. decorate the room is equal to the perimeter of Ann’s living room. Since the perimeter is the sum of the lengths of the four sides of 5. The correct answer is D. The idea of “Manifest Destiny” the room, the perimeter can be written: proposed that the United States had a right to spread its 18 ft 18 ft 12 ft 12 ft and is equal to 60 feet. The civilization across the continent. Though economic gain number of rolls of border needed is determined by dividing the motivated much of the westward expansion in the 1800s, the perimeter by the length of each roll of border. notion of a Manifest Destiny provided an ideological basis for conquering and/or acquiring Native American, Mexican, and 60 ft 1 rolls 7 Canadian lands in North America. 8 ft 2 1 Since Ann needs a minimum of 7 rolls 6. The correct answer is D. Article II of the United States 2 Constitution spells out the powers of the President. Among them and no partial rolls are sold, she must buy 8 rolls. The cost of 8 is the power to reject, or veto, a law that is passed by the rolls of the border is found by multiplying the cost of each roll, Congress. Only the House of Representatives has the power to $6.47, by the number of rolls needed. impeach a federal official or a judge, A. Passing laws, B, is the $6.47 8 = $51.76 duty of the Congress; and coining money, C, is a power reserved to the Congress. The correct answer is B. 7. Choice A is the correct answer. Given that M = 2N, dividing 13. According to the graph, the total amount budgeted for the both sides of the equation by 2 yields M/2 = N, which is school trip is $12,000 and the percent of the total budget equivalent to writing (1/2)M = N. allocated to transportation is 27%. To find 27% of $12,000, express 27% as a decimal, 0.27, and multiply $12,000 by that 8. Choice D is the correct answer. If the average number of decimal. 0.27 × $12,000 = $3,240. Thus, $3,240 is the amount miles per gallon the car gets were known, the number of gallons budgeted for transportation. The correct answer is D. used could be calculated by dividing the total miles driven (the sum of the distances in the problem) by the average number of miles per gallon. 7 Copyright © 2009 by Educational Testing Service.

  • Vocational General Knowledge (0890) 14. According to the graph, the percent of the total budget 19. The correct answer is C. Homeostasis refers to any process allocated for food is 22%, and for lodging it is 39%. The percent that living things use to actively maintain fairly stable conditions allocated for food and lodging is the sum of these two percents. necessary for survival. For example, the human body maintains 22% + 39% = 61%. To express 61% as a fraction, divide 61 by levels of temperature and other vital conditions that are within an 100. acceptable range. Feedback arises out of balances between 61 forces and factors that mutually influence each other. Thus, 100 internal conditions are monitored and, based on feedback Since the question asks which of the given fractions is closest, received, adjustments are made to conditions to keep them 61 within an acceptable range. This is very much like the manner in round 61 to 60, and simplify . 100 which a thermostat works. Air temperature is monitored by the 61 60 3 thermostat, and when the air temperature drops below a preset   level, the thermostat signals the heater to turn on. When the air 100 100 5 temperature returns to the preset level, the thermostat signals The correct answer is B. the heater to turn off. In this way a fairly stable level of air 15. The correct answer is A. According to Ohm’s law, current temperature is maintained. flow may be decreased by decreasing the potential difference 20. The correct answer is C. The European starling was (voltage) and/or increasing the resistance between the ends of introduced into the United States in 1890. Environmental the wire. conditions in the United States were appropriate for the 16. Choice D is the correct answer. None of the incorrect reproduction and survival of this species. However, as happens options describes the most important function of the cell with many exotic species, there are few if any natural predators membrane. The cell membrane does, however, regulate the or competitors in their new habitats. This allowed starlings to movement of substances through the cell boundary. thrive in their new ecosystems and reduce populations of native species. An abundance of predators would have kept the 17. The correct answer is C. A scientific hypothesis is a number of starlings from increasing greatly and, therefore, choice statement that constitutes an informed guess, or prediction, C would not be a factor that contributed to their success. concerning the outcome of a situation. 18. The correct answer is D. Although there are several gases, such as methane, water vapor, and nitrous oxide that are considered to be greenhouse gases, carbon dioxide accounts for the largest percentage of the annual human-caused input of greenhouse gases. 77363-73134 • WEBPDF49 8 Copyright © 2009 by Educational Testing Service.
