gmat CR...explanations please

by r2kins » Wed Jun 23, 2010 10:12 pm
A reason Larson cannot do the assignment is that she has an unavoidable scheduling conflict. On the other
hand, a reason Franks cannot do the assignment is that he does not quite have the assertiveness the task
requires. So, the task must be assigned to Parker, the only supervisor in the shipping department other than
Larson and Franks.

The argument depends on assuming which one of the following?
(A) Larson has the assertiveness the task requires.
(B) The task cannot be assigned to anyone other than a supervisor in the shipping department.
(C) Franks would be assigned the task if Franks had the assertiveness the task requires.
(D) The task cannot be assigned to anyone who has any kind of scheduling conflict.
(E) No one who is not a supervisor in the shipping department has the assertiveness this task requires.

Is A the answer?

IMO B and C are inferences that can be derived from the passage. They're not assumptions on which the conclusion rests.

I have doubt in this.

B,C,D can be inferred from the passage.

If D is the answer then B can also be the answer.Then work cannot be assigned to anyone other than the supervisor.

Experts please comment on the solutions.

IMO : B
If we negate option B,
The task can be assigned to anyone other than a supervisor in the shipping department. - Argument falls apart, Conclusion cannot hold
I am on a break !!

The answer choices are quite confusing. What's the problem with 'C'?

Here one doubt

If we negate D,The task can be assigned to anyone who has any kind of scheduling conflict.

The argument falls apart.

An assumption is an unsaid premise of the stimulus. Premises are given in a stimulus to for / against the conclusion. C does nothing like that. Hence C cannot be the answer.

A - Nowhere is the author assuming this

C - As above

D - D is an inference from the passage not an assumption

E - again author nowhere assumes this

On the contrary, if B is not assumed, the author's conclusion the task must be .... only supervisor ... will fall apart.

IMO B

I selected D.

B : The statement is not saying anything about the other people

D : If you negate D then the conclusion will not be valid.
(In such case we can assign the work to Larson. -> conclusion will be false)

I had answered 'B', but now I see why 'D' is a better answer than 'B'.

The final sentence reveals that Larson, Franks, and Parker are the only 3 supervisors in the Shipping Dept. When I read that the task must be assigned to Parker, I assumed this meant that the task must be assigned to Parker because he's the only other supervisor in Shipping. Now I realize that this isn't necessarily true.

If the statement had read "So, the task must be assigned to Parker, because he is the only supervisor in the shipping department other than Larson and Franks", I'd say that 'B' was too good an answer to dispute. However, the two phrases "the task must be assigned to Parker" and "...the only supervisor in the shipping..." can exist as two independent pieces of information; there is no inherent dependency. For all we know, the non-supervisors in Shipping each has a scheduling conflict, insufficient assertiveness, or some other flaw which precludes he or she from being given the task.

On the other hand, we know that Larson could not be assigned the task because of a scheduling conflict.[/b]

D is NOT assumed, as what is assumed is that the task cannot be assigned to anyone who has an UNAVOIDABLE scheduling conflict. If Larson had an avoidable conflict, this conflict might not prevent her from being assigned the task.
