Traditionally, decision-making by managers that is reasoned step-by-step has been considered preferable to intuitive decision-making. However, a recent study found that top managers used intuition significantly more than did most middle-or lower-level managers. This confirms the alternative view that intuition is actually more effective than careful, methodical reasoning.

The conclusion above is based on which of the following assumptions?

The conclusion above is based on which of the following assumptions?

(B) Top managers have the ability to use either intuitive reasoning or methodical, step-by-step reasoning in making decisions.

(C) The decisions made by middle-and lower-level managers can be made as easily by using methodical reasoning as by using intuitive reasoning.

(D) Top managers use intuitive reasoning in making the majority of their decisions.

(E) Top managers are more effective at decision-making than middle-or lower-level managers

答案是E 没有问题。

但是B为什么错了？ OG解释 B is inappropriate. Since the ease with which a method is implemented is not at issue

我一开始的理解是如果Top managers没能力用step-by-step的方法（当然说Top没能力有点可笑，但不是没可能，他们面对的问题太复杂，正常人都没能力step-by-step地分析也是有可能的），不就能解释为什么他们更倾向于用intuition了吗，从而weaken了结论。排除他因正式assumption的一个方向嘛。

当然E更好。

只是不知道怎么判断B无关呢？还是我的思路有问题？ 请指教！！

比较一下B和E

B) Top managers have the ability to use either intuitive reasoning or methodical, step-by-step reasoning in making decisions.但是没说middle &lower managers就没有能力，也没讲他们谁的 intuitive reasoning 更好，没有比较，就算无关

(E) Top managers are more effective at decision-making than middle-or lower-level managers
