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May老师回答】这题鸡精提供的答案是D 可是我觉得第二个条件不能得出呢 假设n三次方是x平方 除以n平方 是可以得到x/ n 平方 但是x/n 不一定是整数呀？

7.15/寂静：STUVW, 5个人， V和W中间必须隔一个人，求问共有几种组合？ 我的想法是这样的A（3,3）*A(2,2)*C(3,1)=36种；思路如下：先把V+C(3,1)+W看成一个整体；可得：A(2,2)*C(3,1)种排法；然后5个人可分成三类，于是A(3,3)。不知道我的想法对不对，请老师解答。感激不尽！

急求此题！谢谢老师！题目来7/6自寂静。x∈{1, 2, 3}，y∈{4,5,6}，z∈{7,8,9}，求yxx与z的乘积为偶数的概率？我根据求反可得：2/3x1/3x2/3=4/27 1-4/27=23/27 不等于5/9呀？我就是卡在这里了求教。谢谢！

不是很明白为什么A选项不对 我觉得outnumber了给其他人写信的数量可以作为这个period Emily写信的结果出现 为什么不能用现在分词呢？
