Last spring a Colorado health department survey of 72 playgrounds in private child-care centers found unsafe conditions in 95 percent of them and they ranged from splinters to equipment near collapse.
A).. B) conditions in 95 percent were unsafe and ranging C) the ranging of unsafe conditions in 95 percent of them to be D) that 95 percent hadunsafe conditions ranging E) that 95 percent of them had conditions that were unsafe; the range was 安全排除ABC 勉强选的D，可是我没弄明白，D里95%是谁的95%呢？我觉得它也不太对啊。求解答，多谢！！
first of all, agree that D is correct. 2nd, I believe logically it should be: 95% of the playgrounds: 95% of the playgrounds in private child-care centers had unsafe conditions... between playgrounds and child-care centers, i vote for the former because the survey was targeting at the former...
