Which of the following, if true, weakens the product director's argument?

A) The project manager with the weakest technical skills also has the weakest human skills.
B) The Prensabi project is so large that the project manager for the Prensabi project will be unable to take on any other projects until the Prensabi project is finished.
C) The requirements of the Prensabi project are highly unusual.
D) The project manager with the strongest technical skills has no experience with motion-capture technology.
E) The project manager with the strongest conceptual skills has the weakest technical skills.

Answer: D
Explanation: D) Technical skills are required, and so the product director wants the person with the strongest technical skills. That isn't ridiculous, but what if that person doesn't have the specific technical skills that this project requires? If Choice D is true, then the person with the strongest technical skills does not have the technical skills required for this project. Choice A provides an additional reason not to choose the manager with the weak technical skills, but no one is recommending that manager anyway. Choices B and C: Knowing that the project is time-consuming (Choice B) and/or unusual (Choice C) doesn't tell us who should be managing it. Choice C might have been tempting, but we don't know why the project is unusual or how that would affect the requirements for the manager. Choice E is a reason not to pick the manager with the strongest conceptual skills, but it argues against the executive and not the product director. Even on that task, Choice E is weak because the executive believes that the manager should have some technical skills, and, for all we know, the manager with the weakest technical skills still has enough technical skills to do the job.
