Please help in the following question. Although i selected choice E, choice D also looks good. Did not understand why choice D is wrong. I can easily stumble between the two choices. Guess will not work in the real exam.

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?

(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.

Answer is E

Thanks & Regards
Sachin

This CR exhibits a language shift.

The premise is about X: TOP MANAGERS use intuition.
The conclusion is about Y: intuition is MORE EFFECTIVE.
The assumption is that X is connected to Y: that TOP MANAGERS are MORE EFFECTIVE.

Only answer choice E makes this connection: Top managers are more effective at decision-making than middle- or lower-level managers.

The correct answer is E.

Answer choice D is not the assumption but a restatement of the premise: that top managers use intuition.

IMO E.

Please post your queries after the question as it makes us prejudiced before answering. :)

D is a restatement as said by Mitch.
E when negated - the argument falls apart.

Conc: Top managers use intuition more than middle/lower level managers so intuitive decisions are effective.

E Negation - Top managers are not more effective at decision making than middle or lower level managers.

The argument falls apart without this assumption.

IMO E.
