63、Traditionally，decision making by managers that is reasoned step-by-step has been considered preperable 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？

A、Methodical，step-by-step reasoning is inappropriate for making many real-life management decisions。

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。

 推理：TOP MANAGER比中低层MANAGER多用INTUITION作决定，所以INTUITION比

REASONING更EFFECTIVE。前提是TOP MANAGER作的决定比中低层 MANAGER的EFFECTIVE

（即E），如果比他们无效，说明TOP用的INTUITION不好，不会去用它.
