63. 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. 问Assumption
(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
答案是E
菜鸟问题：我看不懂OG对D和A的解释，大家帮帮忙？谢谢
the argument is consistent with managers at all levels using intuition in the minority of decisions made. Thus, choice D is inappropriate.
To the extent that less effective methods are inappropriate, the passage does not assume A, but argues for it.
The explanation to D is that D would be untrue and the argument still holds. It says that "the argument is consistent with ..." to show that it is possible that all managers are using intuition for most of decisions, e.g. top managers make 10% of the decision using intuition while lower managers use intuition for 5% of decision.
A is what the argument is trying to prove, not an assumption. If you do not know what assumption is, you have not started CR.
B的解释为since the argument leaves open the possibility of situations in which top manager are unable to use one of the methods ,choice B is inappropriate.这其中leaves open the possibility of situations 是什么意思？如果对B取非，高层主管什么都不会用，那结论肯定不成立，所以B 也是ASSUMPTION啊。请大家指点！
当B取非以后，意思是高级经理没有能力用感觉推理或按部就班的推理。对结论并没有什么作用。换句话说高级经理有没有能力用……，对结论This confirms the alternative view that intuition is actually more effective than careful, methodical reasoning没有任何削弱作用～～
比如答案B，OG解释说：Since the argumentleaves open the possibility of situations in which top managers are unable to use one of the methods, choice B is inappropriate ，就是在说原文的argument成立的情况下有可能top managers are unable to use one of the methods，也就是B不成立。 D也是类似的原因
The explanation to D is that D would be untrue and the argument still holds. It says that "the argument is consistent with ..." to show that it is possible that all managers are using intuition for most of decisions, e.g. top managers make 10% of the decision using intuition while lower managers use intuition for 5% of decision.
A is what the argument is trying to prove, not an assumption. If you do not know what assumption is, you have not started CR.
还是没有看懂OG对D的解释，为何...in the minority of decision made? 即便是对D取非，the argument 也不一定 consistent with ..., 文中没有提到过minority的有关信息啊？
