Directions: The next questions are based on the content of the following passage. Read the passage and then determine the best answer choice for each question. Base your choice on what this passage states directly to implies, not on any information you may have gained elsewhere.
For each of Questions6-10, select one answer choice unless otherwise instructed.
There can be one doubt that emergence of the Negro writer in the post-war period stemmed, in part, from the fact that he was inclined to exploit the opportunity to write about himself. It was more than that , however. The movement that has variously been called the “ Harlem Renaissance,” the “Blank Renaissance” and the “New Negro Movement” was essentially a part of the growing interest of American literary circles in the immediate and pressing social and economics problems. This growing interest coincided with two developments in Negro life that fostered the growth of the New Negro Movement. These two factors , the keener realization of injustice and the improvement of the capacity for expression, produced a crop of Negro writers who constituted the “Harlem Renaissance.”
The literature of the Harlem Renaissance was , for the most part, the work of a race-conscious group. Through poetry, prose, and song, the writers cried out against social and economic wrongs. They protested against segregation and lynching. They demanded higher wages , shorter hours, and better conditions of work. They stood for full social equality and first-class citizenship. The new vision of social and economic freedom that they had did not force them to embrace the several foreign ideologies that sought to sink their roots in some American groups during the period.
The writers of the Harlem Renaissance, bitter and cynical as some of them were, gave little attention to the propaganda of the socialists and communists. The editors of the Messenger ventured the opinion that the New Negro was the “product of the same worldwide forces that have brought into being the great liberal and radical movements that are now seizing the reins of power in all the civilized countries of the world.” Such forces may have produced the New Negro, but the more articulate of the group did not resort to advocating the type of political action that would have subverted American constitutional government. Indeed, the writers of the Harlem Renaissance were not so much revolting against the system as they were protesting its inefficient operation. In this approach they proved as characteristically American as any writers of the period.
Which of the following is implied by the statement that the writers of the Harlem Renaissance “were not so much revolting against the system as they were protesting its inefficient operation”?

Directions: The next questions are based on the content of the following passage . Read the passage and then determine the best answer choice for each question. Base your choice on what this passage states directly or implies, not on any information you may have gained elsewhere.
Question 17-19 are based on the following passage.
As the works of dozens of women writers have been rescued from what E. P. Thompson calls “the enormous condescension of posterity ,” and considered in relation to each other, the lost continent of the female tradition has risen like Atlantis from the sea of English literature . It is now becoming clear that, contrary to Mill’s theory , women have had a literature of their own all along. The woman novelist, according to Vineta Colby, was “really neither single nor anomalous , ” but she was also more than a “register and spokesman for her age . ” she was part of a tradition that had its origins before her age, and has carried on through our own.
Many literary historians have begun to reinterpret and revise the study of women writers. Ellen Moers sees women’s literature as an international movement, “apart from, but hardly subordinate to the mainstream : an undercurrent , repaid and powerful. This ‘movement’ began in the late eighteenth century , was multinational , and produced some of the greatest literary works of two centuries , as well as most of the lucrative pot-boilers.” Patrica Meyer Spacks, in the Female Imagination, finds that “for readily discernible historical reasons women have characteristically concerned themselves with matters more or less peripheral to male concerns , or at least slightly skewed from them. The differences between traditional female preoccupations and roles and male ones make a difference in female writing.” Many other critics are beginning to agree that when we look at women writers collectively we can see an imaginative continuum , the recurrence of certain patterns, themes , problems , and images from generation to generation.
the author’s attitude toward the literary historians cited can best be described as one of

In 1798 Thomas malthus wrote “An essay on the Principle of Population, ” in which he postulates that food supply never can keep pace with the rate of increase in human population. Increase the supply of food, Malthus argues, and population will rise to meet this increase.

Contemporary literary scholars have come to discard the once-conventional image of English theater in the time of Elizabeth I as an anomalous literary wonder , a sudden flowering of creativity rooted not in the dramatic traditions of England but the theater of ancient Greece and Rome. While acknowledging the debt of the Elizabethan playwrights to the dramas of terence, plautus, and Seneca, and to the Poetics of Aristotle, the majority of theater scholars today regard Elizabethan drama as being organically related to traditional English drama, above all to the medieval cycles of mystery and morality plays.

سوال 48 از 80 سوال
48. سوال
Given the persistent and intransigent nature of the American race system , which proved quite impervious to black attacks , Du Bois in his speeches and writing moved from one proposed solution to another , and the salience of various parts of his philosophy changed as his perceptions of the needs and strategies of black Amrica shifted over time. Aloof and autonomous in his personality , Du Bois did not hesitate to depart markedly from whatever was the current mainstream of black thinking when he perceived that the conventional wisdom being enunciated by black spokesmen was proving inadequate to the task of advancing the race. His willingness to seek different solutions often placed him well in advance of his contemporaries , and this, combined with a strong-willed, even arrogant personality made his career as a black leader essentially a series of stormy conflicts.
Thus Du Bois first achieved his role as a major black leader in the controversy that arose over the program of booker T.
Washington , the most prominent and influential black leader at the opening of the twentieth century . amidst the wave of lynchings , disfranchisement , and segregation laws, Washington , seeking the good will of powerful whites, taught blacks not to protest against discrimination , but to elevate themselves through industrial education , hard work , and property accumulation; then, they would ultimately obtain recognition of their citizenship rights. At first Du Bois agreed with this gradualist strategy , but in 1903 with the publication of his most influential book, Souls of Black Falk , he became the chief leader of the onslaught against Washington that polarized the black community into two wing- the “conservative” supporters of Washington and his “radical” critics.

سوال 58 از 80 سوال
58. سوال
At night, schools of prey and predators are almost always spectacularly illuminated by the bioluminescence produced by the microscopic and larger plankton . the reason for the ubiquitous production of light by the microorganisms of the sea remains obscure , and suggested explanations are controversial . It has been suggested that light is a kind of inadvertent by-product of life in transparent organisms. It has also been hypothesized that the emission of light on disturbance is advantageous to the plankton in making the predators of the plankton conspicuous to their predators! Unquestionably , it does act this way . Indeed, some fisheries base the detection of their prey on the bioluminescence that the fish excite. It is difficult , how ever, to defend the thesis that this effect was the direct factor in the original development of bioluminescence, since the effect was of no advantage to the individual microorganism that first developed it . perhaps the luminescence of a microorganism also discourages attack by light-avoiding predators and is of initial survival benefit to the individual . As it then becomes general in the population , the effect of revealing plankton predators to their predators would also become important .
