出題的教授，從GMAT摘錄~Some soil scientists have asserted that decaying matter on the forest floor is a far greater source of acidity in mountain lakes than is the acid rain that falls on these lakes. Therefore, they contend, reducing acid rain will not significantly reduce the acidity levels of mountain lakes. Which of the following statements, if true, most seriously weakens the argument above?這題考邏輯耶？？您知道嗎？？地球暖化，酸雨才是far greater source lll

還有，這題本身是表達疑問，句子才出現倒裝或省略is the acid rain通常的句子，您是這樣寫的嗎？？
