| There can be no doubt that the
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 "Black 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 economic 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 A.

A.正确 B.错误 [单项选择]At some point during their education, biology students are told about a conversation in a pub that took place over 50 years ago. J. B. S. Haldane, a British geneticist, was asked whether he would lay down his life for his country. After doing a quick calculation on the back of a napkin, he said he would do so for two brothers or eight cousins. In other words, he would die to protect the equivalent of his genetic contribution to the next generation.
The theory of kin selection—the idea that animals can pass on their genes by helping their close relatives—is biology’s explanation for seemingly altruistic acts. An individual carrying genes that promote altruism might be expected to die younger than one with "selfish" genes, and thus to have a reduced contribution to the next generation’s genetic pool. But if the same individual acts altruistically to protect its relatives, genes for altruistic behavior might nevertheless propagate. Acts of apparent altruism to non-relatives can A. innate human hostility. B. his privileged status. C. apparent altruism. D. his sacrifice resources. [单选题]1600仪器做SSA项目血清样本量一次加( )ul。
