Company president: Our consultants report that, in general, the most efficient managers have excellent time management skills. Thus, to improve productivity I recommend that we make available to our middle-level managers a seminar to train them in techniques of time management.

We need to find the odd one that does not weaken the argument.


(A) The consultants use the same criteria to evaluate managers’ efficiency as they do to evaluate their time management skills.
weakens the argument, because, if same criteria or parameters used to evaluate both efficiency & time management, then they are measuring the same thing=> they're interchangeable. In argument though they are not considered interchangeable, that is, they are different. Eliminate

(B) Successful time management is more dependent on motivation than on good technique.
This weakens as motivation is the factor for successful time management, then good technique is not considered as important as motivation for successful time management. Eliminate

(C) Most managers at other companies who have attended time management seminars are still unproductive.
This weakens again, that time management seminar is not useful. Eliminate

(D) Most managers who are already efficient do not need to improve their productivity.
The argument considers only managers who are not efficient. Hence, already efficient manager is irrelevant to the argument. Hence, this does not weakens, keep.

(E) Most managers who are efficient have never attended a time management seminar.
This weakens, that efficient managers never attend time management seminar. This gives only the result or effect, but there is no cause for it. Eliminate

Hence D is the best answer choice.

Each of the following, if true, would weaken the support for the company president’s recommendation EXCEPT:

(A) The consultants use the same criteria to evaluate managers’ efficiency as they do to evaluate their time management skills.

(B) Successful time management is more dependent on motivation than on good technique.

(C) Most managers at other companies who have attended time management seminars are still unproductive.

(D) Most managers who are already efficient do not need to improve their productivity.

(E) Most managers who are efficient have never attended a time management seminar.

Why bother about managers who are already efficient? It is for those who lack it. (D) does not weaken so it is correct.
