When Jamaican-born social activist Marcus Garvey came to the United States in 1916, he arrived at precisely the right historical moment. What made the moment right was the return of (5) African American soldiers from the First World War in 1918, which created an ideal constituency for someone with Garvey's message of unity, pride, and improved conditions for African American communities. (10) Hoping to participate in the traditional American ethos of individual success, many African American people entered the armed forces with enthusiasm, only to find themselves segregated from white troops and subjected to numerous indignities. They (15) returned to a United States that was as segregated as it had been before the war. Considering similar experiences, anthropologist Anthony F. C. Wallace has argued that when a perceptible gap arises between a culture's expectations and the reality of (20) that culture, the resulting tension can inspire a revitalization movement: an organized, conscious effort to construct a culture that fulfills long standing expectations. Some scholars have argued that Garvey created (25) the consciousness from which he built, in the 1920s, the largest revitalization movement in African American history. But such an argument only tends to obscure the consciousness of identity, strength, and sense of history that already (30) existed in the African American community. Garvey did not create this consciousness; rather, he gave this consciousness its political expression.

请唐塘老师分析一下这道题，谢谢

想问下may老师什么时候变化率的计算公式 什么时候分母是被减数，什么时候是减数 像这题求时间的变化率分母是距离也就是被减数，但是对于其他年增长之类变化率的分母就是减数，想知道这个区别，谢谢老师

请文静老师解答：老师我读主旨大概总结为：各个政府开出优惠政策来吸引商家只会两败俱伤，这样不会创造更多的就业岗位，只会影响工作的布局。觉得B很核心的反应了文章主旨。因为从文章主旨上读出这样的行为各个政府都不受益只是影响工作布局罢了，那为什么政府还要重点关注E里竞争者开的条件呢？

老师您在讲课的时候把总数设为了a,将有副作用设为y,将有疗效设为了x,那通过条件（1）就可以知道有疗效为0.9a,没有疗效为0.1a,但是是怎么得出“没疗效有副作用”也为0.1a从而结合题设把y用a的式子表示的呢？感觉只能得出T这一栏里“没有疗效”的总数为0.1a哇

[急] 这题七龙珠答案给的C，但是这里的contemporary只能是形容词或者名词，是不是不能直接接在名词后面用？如果这是个硬伤的话，E会不会更好一些呢？

[急] 请问May老师，这里通过连接下面圆的圆心，是不是是不是可以得到r跟b的直接关系，这样选A是不是就可以了呢？

当时老师讲的答案是A。statement 1 sufficient；statement 2 not sufficient。但是我现在不太理解了，觉得答案有些问题，能不能再详细的讲一下这道题怎么做？谢谢！
