标题: 大全-III-14

14. The president of a consulting firm analyzed the decisions made about marketing by her clients and concluded that the decisions were correct only about half of the time.

The conclusion above depends on the presupposition that

(A) companies can be successful even when about half of the decisions they make about marketing prove to be wrong

(B) companies hiring her consulting firm make no more incorrect marketing decisions than do companies in general

(D) marketing decision are just as likely to be correct as they are to be incorrect（E）

(E) it is possible to classify a marketing decision properly as being either right or wrong

问题：个人认为E项的意思为：市场策划可以被评估为正确的或是错误的。

而原文意思是“市场策划有一半的可能性能够成功”。E项不完全符合原文之意呐。

大家多多指正哦。

只能试着说一下5，因为B跟classic music 没关系。

还有，以后发帖提问的时候标题最好说明题目出处，题号。比如说，这个帖子用“gemj 大全2，4，5”。这样回答问题的人会比较多的。置定帖有关于发帖格式的。

我也不懂，half of the time是什么意思？？我选了D

試著解釋一下…

題目是說一間公司的總裁認為做市場決策只有一半是正確的。那前題自然是市場決策要可以被認定是對錯與否。

After the president analyzed the decision, then made conclusion…, 既然他能立刻说一半真确，一半错误，那么他显然能真确划分它们。

以下是引用guhuo在2005-4-9 12:11:00的发言：

I agree.

嗯，guhuo的解释明白了，但觉得D也对啊，请问D错在哪里了呢？

Bow in advance

取非看看

对E取非无论如何也得不出结论来 if it's NOT possible to classify a marketing decision properly as being either right or wrong, how could the president draw the conclusion that the decisons were correct only about half of the time.

对D取非 if maketing decisions are NOT likely to be correct as they are to be incorrect, the president could still be able to reach his conclusion, if he has the ability to classify a marketing decision.

I think the emphasis of this problem is on the president's ability to classify a marketing decision but not the marketing decision itself.

我觉得这是个假设题，必须找到一个使结论成立的必要条件，而非充分条件

结论the decisions were correct only about half of
the time成立，E必须成立（主席得有可能把市场决策划分为错的或是对的）

结论the decisions were correct only about half of
the time成立，D不一定成立（市场决策是正确的可能性是50%，与错误的可能性相同）

half of the time 只在半数情况下正确是对了一半的意思啊？！
