1.Which of the following most logically complete the passage？　　A recent government study links the high rates of respiratory ailment in Groverston to airborne pollutants released by the Woodco plywood manufacturing plant there. To address the problem， the government imposed strict regulations on emissions which will go into effect in four years. Although Woodco plans to cut its emissions in half two years ahead of schedule， it is unlikely that the rate of respiratory ailments will decline before the regulations go into effect， since＿ .
　　A.the number of facilities capable of treating respiratory ailments is not likely to increase
　　B.reducing emissions even further than planned would necessitate decreasing production at Woodco
　　C.it is difficult to make accurate， long-term predictions about emissions
　　D.not all respiratory ailments are caused by airborne pollutants
　　E.three new plywood manufacturing plants are about to go into production in Groverston
我的问题是D为什么不可以。如果有其他因素导致污染的话，就算plywood停产也会导致污染量不减少，不是吗？
D选项对原文中的因果关系进行削弱，指出其他原因可能存在，不支持结论。
这是我在网上找到的新东方对此的解释，但是这个解释，我真的看不懂，本人逻辑差生，求大家帮帮忙！！

楼主看过OG解释吗？能把OG解释贴上来让我看看咩，我也很好奇这道题。
这题的结论应该是the rate of respiratory ailments will decline if the regulations go into effect，是conditional conclusion.
新东方的意思是说这道填空题解释上述结论原因，属于加强型，所以答案应该是加强结论。
D选项是weaken结论的，所以不对。
如果楼主是不懂为什么它因削弱题目，建议去看看bible和牛人的帖子。

og对于d的解释：this information raises the possibility that within the next four years, an increase in the occurrence of factors other than ariborne pollutants might make a decline in repiratory ailments unlikely. However, the passage provides no information whatsover that implies an increase in the occurrence of such "other"factors。
谢谢你，因为马上要出门可能打得有点乱，见谅见谅。bible我看的是gmat的，看到一半就停了，还是继续看下去吧。

因为这道题的前提条件已经设定，就是A recent government study links the high rates of respiratory ailment in Groverston to airborne pollutants released by the Woodco plywood manufacturing plant there.    by the Woodco plywood manufacturing plant there.就已经将作者的观点限制在这个条件下，文中没有指出其他原因会导致respiratory ailment ，所以D选项是他因，就是跑题了~

因為他問  為什麼只有到 4年後的 關於減排的regulation出來 才能阻止 疾病  
如果選D  那 連regulation 也沒不能阻止疾病了。
