【正确答案】 D

【答案解析】从"Hannon，who was hired to teach math at Gage Park High School，says classrooms in Chicago are very different from those in Palestine．”可以判断A不正确。B、C两项在文中并未出现，可排除。因此D为正确答案，依据为“He says in Palestine，the culture forces students to work hard because if they don't they'll be kicked out and put in vocational schools，which limits their career options．There is not nearly as much pressure for American students to do well．”
