标题: OG10-80求解

The program to control the entry of illegal drugs into the country was a failure in 1987. If the program had been successful, the wholesale price of most illegal drugs would not have dropped substantially in 1987.

The argument in the passage depends on which of the following assumptions?

(A) The supply of illegal drugs dropped substantially in 1987.

(B) The price paid for most illegal drugs by the average consumer did not drop substantially in 1987.

(D) The wholesale price of a few illegal drugs increased substantially in 1987.
(E) A drop in demand for most illegal drugs in 1987 was not the sole cause of the drop in their wholesale price.
请牛牛帮忙看下这道题目，OG分类lawyer版的解释是这样的，但是还是不能理解，可否再解释下，谢谢！The researcher concludes from the association of low immune-system activity with low mental-health sores that, in effect, immune system activity can inhibit mental illness. If, contrary to D, mental illness can depress immune-system activity, the association mentioned does not support the researcher’s conclusion. So D must be assumed.

标题: 不好意思刚才解释帖错了 lawyer版的解释是这个
The only choice that must be true in order to conclude legitimately from the drop in the wholesale price of illegal drugs that the program was a failure is choice E, the best answer. If the drop in price was caused by a drop in demand, there is no reason to suspect that there has been any increase in supply caused by drugs entering the country.

我的理解是 program是控制药品流入的，1987的 program失败了导致大量不合法药品进入数量增加需求减少所以价格下降，那E又说需求减少不是价格下降的主要原因这样就推不出原来的结论了啊所以不理解有没有人给解答下啊

you can just deny the choice e in order to test whether answer e is reliable.

if the answer e is wrong, in other words, if the drop in demand is the only reason of the lower price, definitely , the argument will be weaken, since we can conclude from the argumenet that the failure of the program led to the drop of the illgeal price.

讓我們先來讀讀題目,是假設題型
然後看文章,哇有個虛擬語氣,引起一下重視,然後看premise,control的提案失敗,結論,提案的失敗導致了price drop

不用任何套路去解題的方法:　
premise: control失敗
隱含的假設:大量的國外貨物涌入國內,造成供貨量多,由于供大于需
結論,price drop

那麽你隱含的假設說,供大于需,當然不能是需小于供啦,要是需求减少,供應跟以前一樣多,同樣是造成供大于需的現象,但是原因不一樣
(看起來一樣,但實際不一樣)
所以我就要建立在需不會少于供的假設下,答案就是e,也是not+weaken的形式,排除他因.看到assumption的題目,上來直接先找not+weaken,不對再看其他選項

按照套路解題:
premise,control的提案失敗,結論,提案的失敗導致了price drop

這個是典型的　correlation 錯誤的定為　cause and effect,　提案的失敗跟price drop發生在一起,就說提案是price drop的原因,要基于一個假設,對于因果的比較典型是說price drop不是提案失敗的原因　(因果顛倒)　,可是這道題目不是這樣的.那麽我們再看　排除他因:不是其他因素cause price drop.比如說供需關係的變化的影響,因爲不加控制,在需求不變的時候,供應就變多,進來方便,而且有利可圖,看到了,不輕易間,"在需求不變的時候"這個就是你的假設了.

建議樓主看lawyer的解題方法,lawyer的方法有如高深的簡譜,不多,但精闢,組合起來,變化多端,光是結論的具體性和特殊性著６個單詞,就可以讓你更上一層樓了
