The poet Paul Laurence Dunbar (1872-1906) was the premier Black writer of poetry that used the dialect of rural African Americans of the southern United States. Although Dunbar's works were both popular with readers and acclaimed by literary critics during his lifetime, after the First World War a radical shift occurred, at least in critical opinion of his poetry, and twentieth-century critical evaluation of his work has been generally negative. Some critics attacked his work on social grounds for failing to challenge plantation stereotypes of African Americans. Other critics, such as the poet James Weldon Johnson, argued from aesthetic grounds that dialect poetry in general was too limited as an artistic medium, and capable of producing only two effects: pathos and humor. The negative critical trend only began to reverse itself in the 1970s, when scholars began to emphasize the importance of mythic, psychological, and historical dimensions of Dunbar's works, focusing on the interior and exterior realities of African American life after the Civil War.
Which of the following can be inferred from the passage concerning scholars' use of mythic, psychological, and historical considerations in evaluating Dunbar's works?
A. Such use disputes the claim that Dunbar's work failed to challenge plantation stereotypes of African Americans.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.
As presented in the passage. McGill's account of the formation of Mars's northern basin differs from the others mentioned in that it alone
