Presupposition:)

by S0laris » Sat Mar 14, 2009 9:40 am

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
(C) executives consistently making correct marketing decisions rarely enlist the aid of a consulting firm
(D) marketing decision are just as likely to be correct as they are to be incorrect
(E) it is possible to classify a marketing decision properly as being either right or wrong

we are the champions !

IMO E

A, B and C are out of scope.

D doesnot sound right. We need a concerte way to segregate the marketing decisions. D states that it depends upon a view point or perspective.

E - Correct

OA pls?

The answer is E. If it were impossible to classify a marketing decision as either right or wrong, then the the president of the firm would not have been warranted in concluding that half of the decisions were wrong. For her to make that determination, she had to have had the ability first to classify the marketing decision as right or wrong, and then determine that nearly half of the decisions were in fact wrong.
