The World Wildlife Fund has declared that global warming, a Phenomenon most scientists agree to be caused by human beings in burning fossil fuels, will create havoc among migratory birds by altering the environment in ways harmful to their habitats.
(A)a phenomenon most scientists agree to be caused by human beings in burning fossil fuels,
(B) a phenomenon most scientists agree that is caused by fossil fuels burned by human beings,
(C)a phenomenon that most scientists agree is caused by human beings' burning of fossil fuels,
(D)which most scientists agree on as a phenomenon caused by human beings who burn fossil fuels,
(E)which most scientists agree to be a phenomenon caused by fossil fuels burned by human beings,
题目分析：ABC开头都说a phenomenon，属于犀牛望月式，答案就在abc里面，ABC在phenomenon后面的语义是修饰这个词汇的，可是A没有that就无法体现后面修饰前面这层关系，如果that放在了B选项的位置，这个that修饰谁了？只有Cthat那个位置我感觉that修饰的是phenomenon。选c。
