xq0609

Mideast immigrants' rates of entrepreneurship exceed  virtually every other immigrant group in the increasingly diverse United States economy.

(A) Mideast immigrants' rates  of entrepreneurship exceed
(B) Mideast immigrants are exhibiting rates of entrepreneurship  exceeding
(C) Immigrants from the Mideast exhibit rates of entrepreneurship exceeding those of
(D) The rates  of entrepreneurship in immigrants from the Mideast exceed
(E) The rates of Mideast immigrants' entrepreneurship exceeds those of

看了语法笔记里说在GMAT中,双重所有格,即 the rates of immigrants’ 表达错误, 应该改为the rates of immigrant或者 immigrants’ rates
而E选项：使用双重所有格,错误; 主谓不一致:主语是rates,谓语应该用exceed.
很想求助下，The rates of Mideast immigrants' entrepreneurship 这种表达正确吗？属于双重所有格吗？总觉得immigrants'是修饰 entrepreneurship。谢谢
