But invariably, the blues exceed rigid cultural boundaries. Ralph Ellison's definition of the blues suggests an expansive vista, limited only by a speaker's capacity to lyrically express an "autobiographical chronicle of personal catastrophe." As an idiom, the blues record histories, yet Ellison's definition privileges the personal and leaves uncertain the role of national histories, the stories that speak our collective experiences. Locating the collective histories in the personal has proved a pivotal problem for readers in the written use of the blues both in Ellison's fiction and in works by Toni Morrison, Gayl Jones, and others. Consider each of the choices separately and select all that apply. The passage suggests that which of the following is an accurate characterization of the blues as defined by Ralph Ellison? - They are not limited to a specific cultural tradition. - They emphasize personal experience over collective history. - They must appear in written works. ## Section 3 of 5 | Question 5 of 12 Blues music speaks histories that, from the conventional perspective, originate in the experiences of African Americans.

Locating the collective histories in the personal has proved a pivotal problem for readers in the written use of the blues both in Ellison's fiction and in works by Toni Morrison, Gayl Jones, and others. Select the sentence in the passage that describes a particular alternative to the conventional perspective on the blues. ## Section 3 of 5 | Question 6 of 12 The indigenous uprising in Bolivia in 2008 was not ______: in 1781 indigenous people took over the area near present-day La Paz in what constituted the biggest challenge to the Spanish who then controlled Bolivia. - unsuccessful - unprecedented - unpredictable - disregarded - unique - random ## Section 3 of 5 | Question 7 of 12 The manufacturing company's swift maneuver enabled it to evade the full impact of the increasing cost of raw materials, which brought the downfall of firms that responded less ______. - ruthlessly - deftly - adroitly - carefully - extravagantly - cautiously ## Section 3 of 5 | Question 8 of 12 Although one can adduce myriad examples of ecosystem disruption by nonindigenous species, nevertheless most introduced species that survive in fact appear to have quite ______ effects on the ecosystems they have invaded. - minimal - trifling - marked - conspicuous - intriguing - deleterious ## Section 3 of 5 | Question 9 of 12 Yoshiko Yamaguchi was a remarkably ______ public figure: she was not only an actress but also a journalist, a prominent politician in the Japanese parliament, and the wife of a diplomat. - protean - sporadic - prolific - pedestrian - versatile - prosaic ## Section 3 of 5 | Question 10 of 12 Montesquieu's influence on James Madison and other founders of the American republic, particularly evident in the theory of separation of powers that informs the United States Constitution, is well noted by scholars. Madison's critique of elements of Montesquieu's political philosophy, however, has been given scant attention. The crux of Madison's criticism concerned Montesquieu's praise for the British system of balanced government. According to Montesquieu, the institutional and corporate division of powers and checks and balances established in Britain provided for political moderation and made the English constitution the model of free government in the modern world. Most English politicians and writers agreed with the general assumptions underlying the theory of balanced government advocated by Montesquieu; their disagreement essentially concerned whether the parts of their government were effectively separated and balanced and thus whether liberty was sufficiently protected. A number of French thinkers disagreed with Montesquieu's assumptions, rejecting their countryman's theory of balanced government as any real guarantee of stability or safeguard for liberty. Interestingly, when Madison publicly invoked the name of Montesquieu in his writings of the early 1790s, it was primarily to challenge rather than to celebrate the political wisdom of the French oracle. Madison's proposed alternative to Montesquieu's vaunted British model was grounded in the recognition of public opinion as the ruling authority in republican government. The primary purpose of the passage is to: - consider the origins of a historical controversy - explain how a political theorist adapted ideas to a new context - reexamine the relationship of one thinker's ideas with another's work - dispute the significance of a disagreement between two schools of thought - evaluate the assumptions underlying and argument ## Section 3 of 5 | Question 11 of 12 Montesquieu's influence on James Madison and other founders of the American republic, particularly evident in the theory of separation of powers that informs the United States Constitution, is well noted by scholars.

Madison's proposed alternative to Montesquieu's vaunted British model was grounded in the recognition of public opinion as the ruling authority in republican government. The author regards the situation described in the highlighted sentence as interesting primarily because: - it goes against the prevailing scholarly view about Madison and Montesquieu - it explains Madison's uneasiness with the British system of balanced government - most scholars assume that Madison did not encounter Montesquieu's work until after the 1790s - Madison has never had a reputation for being a controversialist - Montesquieu's thinking was regarded as old fashioned in North America in the 1790s ## Section 3 of 5 | Question 12 of 12 Montesquieu's influence on James Madison and other founders of the American republic, particularly evident in the theory of separation of powers that informs the United States Constitution, is well noted by scholars.

Madison's proposed alternative to Montesquieu's vaunted British model was grounded in the recognition of public opinion as the ruling authority in republican government. The author of the passage would most likely agree with which of the following statements about "their disagreement" with Montesquieu's theory? - It had little effect on the course of British politics. - It was less fundamental in nature than was Madison's disagreement. - It had a noticeable impact on certain important French thinkers. - It caused Montesquieu to rethink certain basic principles - It was based on a crucial misunderstanding of Montesquieu's theory. ## Section 4 of 5 | Question 1 of 15 *r* is a positive integer. | Quantity A | Quantity B | |---|---| | The remainder when the product *(r + 1)(r + 2)(r + 3)* is divided by 5 | 1 | - Quantity A is greater. - Quantity B is greater. - The two quantities are equal. - The relationship cannot be determined from the information given. ## Section 4 of 5 | Question 2 of 15 Circle *A* has radius 4.

If the value of the house at the end of 1994 was $64,000, then x = - 32 - 64 - 75 - 80 - 90 ## Section 4 of 5 | Question 8 of 15 How many different combinations of 5 cards can be chosen from a pack of 52 cards? - *52!/5!(52 - 5)!* - *52!/5!* - *51!/52! - 5!* - *52! - 5!/52!* - *(52 - 5)!/5!* ## Section 4 of 5 | Question 9 of 15 In the xy-plane, the slope of the line shown that passes through points *T* and *M* is -10/3. What is the value of *d*? - 3.8 - 10.2 - 18 - 20 - 22 ## Section 4 of 5 | Question 10 of 15 An investor purchased two properties, A and B. The investor later sold property A at a selling price that was 20 percent more than the purchase price of A, and the investor sold property B at a selling price that was 40 percent less than the purchase price of B. If the combined purchase price of properties A and B was $200,000, and the combined selling price was $210,000, what was the selling price of property A? - $160,000 - $170,000 - $180,000 - $190,000 - $200,000 ## Section 4 of 5 | Question 11 of 15 The average (arithmetic mean) of the measurements in a large sample is 46.2.

They obtained a radiocarbon date of 8,470 years from material associated with the buried point, a date far more recent than the known time range for Clovis points. There are three ways of accounting for this date. First, it is possible that fluted points were in use in this region around 8,470 years ago. Second, this point may somehow have been deposited at the California site long after its creation. Third, the 8,470-year date may be wrong; a second date from the same context providing an age of 4,360 years was rejected by archaeologists as incorrect. Consider each of the choices separately and select all that apply. If the first explanation is the only one of the three that is correct, then it can be inferred that: - the material associated with the buried point and the point itself are not from the same time period - there may be other fluted points in the region that date from about 8,470 years ago - the accepted time range for classic Clovis points may need to be reconsidered ## Section 5 of 5 | Question 6 of 15 In California's Mojave Desert, archaeologists found two fluted projectile points, one on the surface, one buried, both similar to classic Clovis stone points from the American Plains. They obtained a radiocarbon date of 8,470 years from material associated with the buried point, a date far more recent than the known time range for Clovis points. There are three ways of accounting for this date. First, it is possible that fluted points were in use in this region around 8,470 years ago. Second, this point may somehow have been deposited at the California site long after its creation. Third, the 8,470-year date may be wrong; a second date from the same context providing an age of 4,360 years was rejected by archaeologists as incorrect. It can be inferred that the second and the third explanations have which of the following in common? - Each implies that the known time range for classic Clovis points will need to be revised. - Each leaves open the possibility that the California fluted points were created contemporaneously with classic Clovis points. - Each suggests that the radiocarbon Dating used at the California site produced unreliable results. - Each implies that 8,470 years ago, fluted points were more widely used on the American Plains than in the region of the California site. - Each is based on the assumption that the buried fluted point did not originate at the California site. ## Section 5 of 5 | Question 7 of 15 As of the late 1980s, neither theorists nor large-scale computer climate models could accurately predict whether cloud systems Would help or hurt a warming globe. Some studies suggested that a four percent increase in stratocumulus clouds over the ocean could compensate for a doubling in atmospheric carbon dioxide, preventing a potentially disastrous planetwide temperature increase. On the other hand, an increase in cirrus clouds could increase global warming. That clouds represented the weakest element in climate models was illustrated by a study of fourteen such models. Comparing climate forecasts for a world with double the current amount of carbon dioxide, researchers found that the models agreed quite well if clouds were not included. But when clouds were incorporated, a wide range of forecasts was produced. With such discrepancies plaguing the models, scientists could not easily predict how quickly the world's climate would change, nor could they tell which regions would face dustier droughts or deadlier monsoons. The author of the passage is primarily concerned with: - confirming a theory - supporting a statement - presenting new information - predicting future discoveries - reconciling discrepant findings ## Section 5 of 5 | Question 8 of 15 As of the late 1980s, neither theorists nor large-scale computer climate models could accurately predict whether cloud systems Would help or hurt a warming globe.

But when clouds were incorporated, a wide range of forecasts was produced. With such discrepancies plaguing the models, scientists could not easily predict how quickly the world's climate would change, nor could they tell which regions would face dustier droughts or deadlier monsoons. It can be inferred that one reason the fourteen models described in the passage failed to agree was that: - they failed to incorporate the most up-to-date information about the effect of clouds on climate - they were based on faulty information about factors other than clouds that affect climate - they were based on different assumptions about the overall effects of clouds on climate - their originators disagreed about the kinds of forecasts the models should provide - their originators disagreed about the factors other than clouds that should be included in the models ## Section 5 of 5 | Question 9 of 15 As of the late 1980s, neither theorists nor large-scale computer climate models could accurately predict whether cloud systems Would help or hurt a warming globe.

But when clouds were incorporated, a wide range of forecasts was produced. With such discrepancies plaguing the models, scientists could not easily predict how quickly the world's climate would change, nor could they tell which regions would face dustier droughts or deadlier monsoons. The information in the passage suggests that scientists would have to answer which of the following questions in order to predict the effect of clouds on the warming of the globe? - What kinds of cloud systems will form over the Earth? - How can cloud systems be encouraged to form over the ocean? - What are the causes of the projected planetwide temperature increase? - What proportion of cloud systems are currently composed of cirrus clouds? - What proportion of the clouds in the atmosphere form over land masses? ## Section 5 of 5 | Question 10 of 15 Because the critic thought that the mark of great literature was a grandiosity not to be found in common speech, writers seeking his approbation ______ the use of the vernacular. - derided - mistrusted - eschewed - espoused - embraced - shunned ## Section 5 of 5 | Question 11 of 15 Most children overgeneralize the rule that to form a plural you add "s" - saying "foots," for example, instead of "feet" -but they become grammatically more ______ as they get older. - exacting - succinct - adroit - playful - skillful - creative ## Section 5 of 5 | Question 12 of 15 The landmasses that form our continents are notably ______: they are plates of rock continuously shifting around within the Earth's crust, in movements that are not just horizontal but also vertical. - coordinated - dispersed - itinerant - ancient - peripatetic - scattered ## Section 5 of 5 | Question 13 of 15 Treasure hunters as well as archaeologists seek out remains of ancient settlements in central Asia. When treasure hunters find a site, they generally destroy much valuable archaeological information in the process of removing artifacts that they can sell. Guarding the area where unexcavated sites might be found is impossible. Therefore, there is no way to preserve the archaeological value of unexcavated sites unless they can be found and excavated quickly. Which of the following, if true, most strongly supports the argument? - Once treasure hunters have found an ancient settlement, they generally find and extract
