• Question 381:

  Instances of "galactic cannibalism"--mergers in which large galaxies completely consume smaller ones--may be fairly common. Tidal forces produced by the Milky Way's powerful gravity, for example, appear to be dismantling and engulfing a dwarf galaxy in the constellation Sagittarius, producing large clumps and streamers of stars connecting the two galaxies. Astronomers have also observed two dense clusters of stars and gas at the heart of the Andromeda galaxy, an apparent "double nucleus" that may contain the remnant of a cannibalized dwarf galaxy. But this Twin-lobed appearance could also be created by two parts of a single nucleus bisected by a lane of dust. Scientists believe that only about 25 percent of such apparent double nuclei actually represent galactic cannibalism. Many of the rest result from the illusion of proximity that occurs when objects at different distances appear along the same line of sight: others consist of debris from galactic "collisions." in which one galaxy has passed through another without merging, causing waves of new star formation.

  According to the passage, a true double nucleus may be produced by the

  A. collision of two dwarf galaxies

  B. incorporation of a dwarf galaxy into a larger galaxy

  C. merging of two galaxies of approximately equal size

  D. separation of a single nucleus into two parts by a lane of dust

  E. waves of new star formation resulting from an instance of galactic cannibalism

  Correct Answer: D

• Question 382:

  Recent studies of the gender gap in the history of United States politics tend to focus on candidate choice rather than on registration and turnout. This shift in focus away from gender inequality in political participation may be due to the finding in several studies of voting behavior in the United States that since 1980. differences in rates of registration and voting between men and women are not statistically significant after controlling for traditional predictors of participation. However. Fullerton and Stern argue that researchers have overlooked the substantial gender gap in registration and voting in the South. While the gender gap in participation virtually disappeared outside the South by the 1950s, substantial gender differences persisted in the South throughout the 1950s and 1960s, only beginning to decline in the 1970s.

  The author of the passage cites "several studies of voting behavior in the United States" to

  A. suggest that rates of change in political participation have moderated

  B. provide a possible explanation for a propensity among certain researchers

  C. indicate an area of research that is particularly promising

  D. speculate about the implications of a change

  E. suggest that a particular area of study has not been very productive

  Correct Answer: E

  A. disseminate

  C. eradicate

  D. propagate

  E. extirpate

  F. differentiate

  Correct Answer: CE

• Question 384:

  A divide between aesthetic and technical considerations has played a crucial role in mapmakiug and cartographic scholarship. Some nineteenth-century cartographers, for instance, understood themselves as technicians who did not care about visual effects, while others saw themselves as landscape painters. That dichotomy structured the discipline of the history of cartography. Until the 1980s, in what Blakemore and Harley called "the 'Old is Beautiful' paradigm." scholars largely focused on maps made before 1800. marveling at their beauty and sometimes regretting the decline of the pre-technical age. Early mapmaking was considered art while modem cartography was located within the realm of engineering utility. Alpers. however, has argued that this boundary would have puzzled mapmakers in the seventeenth century, because they considered themselves to be visual engineers.

  It can be inferred from the passage that, beginning in the 1980s. historians of cartography

  A. placed greater emphasis on the beauty of maps made after 1800

  B. expanded their range of study to include more material created after 1800

  C. grew more sensitive to the way mapmakers prior to 1800 conceived of their work

  D. came to see the visual details of maps as aesthetic objects rather tlian practical cartographic aids

  E. reduced the attention they paid to the technical aspects of mapmaking

  Correct Answer: B
