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 am! 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, psyclwlogical. 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 Litrary critics’ evaluations of Dunbar's poetry?

The following appeared in a letter to the editor of a Batavia newspaper

"The department of agriculture in Batavia reports that the number of dairy farms throughout the country is now 25 percent greater than it was 10 years ago. Dunne this same time period, however, the price of milk at the local Excello Food Market has increased from SI.50 to over S3.00 per gallon. To prevent farmers from continuing to receive excessive profits on an apparently increased supply of milk, the Batavia government should begin to regulate retail milk prices Such regulation is necessary to ensure fair prices for consumers."
