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.

老师，我今天考试碰到的寂静题，一模一样！然后根本算不出来啊，两个式子结合是30x=5y.不知道寂静答案是怎么算出来x=15 y=90的？

请May老师解答～ 老师，您回复我的这一题，关于圆心角 和 圆周角，我有几个问题想问： 1. ABC是一个优弧，优弧的圆心角是怎么看的呢？为什么是∠BOC，而不是∠AOC呢？ 2. 此图中，（优弧）弧ABC 和 （劣弧） 弧AC是否有同一个圆心角 和 同一个圆周角呢？ 如果不是，老师可否分别把此图中 优弧与劣弧的圆心角和圆周角画一下？ 2. 优弧ABC所对应的圆周角 是∠E（我用红笔加上去的那一个）吗？

请May老师解答，想问一下鸡精的答案是不是错了？我的解答过程有没有问题？
