Renfield should not be promoted to the management position. His performance as a member of our staff, while exemplary, has shown little of his management ability. Everything he has said and done up to this point has been directed toward obtaining this promotion rather than showing us that he has the ability to manage other people.
Therefore, we cannot trust that he will be an effective manager once in the position.Which one of the following is an assumption on which the argument relies?
(A) The duties of a staff member
do not in and of themselves prove that the person is capable of managing people. - CORRECT. If negated i.e. if proved then conclusion false apart. Then one needs to trust Renfield.
(B) Renfield
cannot be trusted even with his current duties as a member of the staff. - WRONG. Current duties may involve many other aspects where he is exemplary.
(C) When Renfield obtains the promotion,
he does not intend to act in the best interest of the staff under his management. - WRONG. Intention is irrelevant.
(D) The
staff will not follow Renfield’s lead as a manager once he receives the promotion. - WRONG. Staff following or not is irrelevant at this juncture.
(E) Managers
rarely are promoted from the staff because they are unable to handle the higher level of responsibility. - WRONG. What has been a trend in the past is not affecting the conclusion.
Answer A.
