What accounts for the low-lying. Hat surface of Mars's north? On Earth's surface, higher- and lower-lying areas have different types of crust: one. thin and dense, is pulled toward Earth's center more strongly by gravity, and the planet's water naturally comes to sit over it. creating oceans. The processes that generate this oceanic crust drive plate tectonics.
Is Mars's north similarly characterized by a sort of crust different from other areas of the planet? Some researchers do see signs of tectonic activity surrounding the northern basin that suggest that it was created through the formation of new crust, like ocean basins on Earth. However. McGill points to northern bedrock structures that predate the features said to mark the start of the tectonic process. McGill instead believes that through some novel mechanism the ancient surface sank to its current depth as a single unit. This would explain why features around the basin's edge. which would have formed as the surface dropped, seem to be younger than structures at its floor.
The third possibility is that the northern lowlands result from impacts. Some researchers suggest they formed as a series of big overlapping impact craters. Others, arguing that the odds against such a pattern of impacts are large, postulate a single event-the impact of an object bigger than any asteroid the solar system now contains.
Which of the following can be inferred from the passage about geological features on Earth?

• A. The formation of low-lying areas proceeds by a different process than the one that created Mars's northern basin.
• B. The difference in elevation between the ocean basins and their surroundings is greater than the difference between Man's northern basin and its surroundings.
• C. The relative elevation of the lowest-lying regions of the crust arises in part from forces generated within the planet.
• D. The proportion of the crust that is oceanic crust is increasing.
• E. The weight of the oceans does not affect the depth of the ocean basins.

Recently, we have seen the emergence of the food movement, or perhaps we should say "movements." since it is (i)_________as yet by little more than the recognition that industrial food production is in need of reform because its social or environmental or public health or animal welfare or gastronomic costs are too high. As that list suggests, the activists are coming at the issue (ii)_________. Where many social movements, over time, break into various factions representing differing concerns or tactics, the food movement has been (iii)_________from its beginning.

• A. impeded
• B. ideological
• C. in increasing numbers
• D. effective
• E. from divergent directions

Harriet Monroe, who founded Poetry: A Magazine of Verse in 1912. argued that the more heterogeneous and sprawling the modem world became, the more poetry needed "an entrenched place, a voice of power." But this goal could only be realized if poets were valued in ways that encouraged them to participate in the world and made writing verse economically viable. Monroe argued that poets needed sites of institutional opportunity like those that had been developed for visual artists, architects, and musicians. She believed that the hand-wringing anticapitalism dominating genteel literary* culture-particularly the idea that poetry ought to be removed from "sordid" pecuniary considerations-brought no economic and only illusory aesthetic benefits, instead severing poets from meaningful participation in the modern world.

• A. acknowledge that anticapitalism had not hail undesirable consequences for all art forms
• B. illustrate the point that some art forms are inherently more economically viable than others
• C. highlight what Monroe regarded as a contrast between the economic needs of poets and those of other artists
• D. note a challenge that Monroe faced when attempting to implement her ideas
• E. explain Monroe's ideas about measures that would advance poetry
