I think C weakens the conclusion because, after a profitable year, even though the company invests more cash in R&D, its team proposes more project ideas than the company has time to act on. If the company's implementation capacity remains the same as in the years following unprofitable years, the additional investment may not translate into more actual innovations. In other words, while the company has more resources and ideas after a profitable year, its limited bandwidth could prevent it from generating more innovations than it would after an unprofitable year. Therefore, increased R&D investment does not necessarily lead to increased innovation.
Can you please explain the fault in my reasoning?
Here's (C):
C. Its research and development team members propose more project ideas that the company does not have time to act on than usual. Notice that (C) does not say what you said, which is "while the company has more resources and ideas after a profitable year, its limited bandwidth could prevent it from generating more innovations than it would after an unprofitable year."
You've suggested that the company's bandwidth limits it in a way such that it cannot generate more innovations.
(C) doesn't say that. (C) indicates that there are more project ideas than the company has time to act on. That doesn't mean that the company doesn't have any ability to increase innovation through increased investment. It means only that the company's ability to act on ideas is not completely unlimited, which is only natural. After all, there are some limits on the time of any company.
So, we can see (C) as saying basically that, after a profitable year, the team members propose more ideas than usual, to a degree such that there are more that the company does not have time to act on. This increase in idea generation should lead to increased innovation, even if the company cannot act on all of them.
Takeaway: To get Critical Reasoning questions correct we have to be careful to stick to exactly what answer choices and other statements say and be careful not to add ideas that are not truly conveyed or implied.
