In this question, we want to find the one answer that does not weaken the argument. That means that the correct answer can strengthen the argument, or it can just be completely out of scope and irrelevant to the argument. The argument is that military research has historically resulted in technologies that have fueled corporate growth, and therefore this new DARPA research initiative will benefit industrial companies as well. This is a very poor "because it happened in the past, it will happen again in the future" argument, making it easy to include a bunch of incorrect weaken answer choices.

A - This weakens the argument. If the research initiative consumes industrial company resources (their brainpower), then it is very likely to hurt and not help those companies.

B - This weakens because if DARPA has a more restrictive stance regarding the use of their IP than they did in the past, then even if they make the same caliber of advancements as in the past the corporations are less likely to benefit from these advancements because DARPA is less likely to share them.

C - This is a similar weakener to answer choice A - if the initiative utilizes resources that would have benefited the companies then that is bad for the companies

D - This is completely out of scope and is thus our correct answer. Whatever else DARPA is working on has nothing to do with this argument. The argument is solely focused on this one research initiative helping corporations.

E - This weakens because if the technology developed is of no use to corporations, then corporations are unlikely to benefit from this initiative.
