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.

PS：一个数是两位数，这个数大于11，个位数和十位数加起来的和是质数，问这样的 数有多少个？

57)If m is a positive odd integer between 2 and 30, then m is divisible by how many different positive prime numbers? 1)m is not divisible by 3. 2)m is not divisible by 5. 条件1 我理解的是 M 只能2到30之间，那么就有5，7，11，13，17，19，23，29，这么多个prime numbers. 条件2 我理解的是 M 可以是 3，7，9，11，13，17，19，21，23，27，29 这些，21可以被3和7除， 我判断条件1完全可以，条件2 我不太确定
