C breaks the argument to smithereens

another vote for E. If it is TRUE E would be most devastating to the argument in this passage. OA Bhai?

Somehow I also think that (E) should be the answer, (Though now-a-days I'm going thru a bad patch as far as CRs' are concerned)
Though it is not mentioned that what kind of harm the option is talking about, but still I think (E) scores over (C), because (C) has a problem with term "well rounded graduate", and passage states that our universities must cultivate dedication and creativity rather than merely convey information.
This means universities must make a person creative, dedicated to work and along with these they should also convey information, which sounds like making an individual all-rounder.

Bit confused here

What's the OA, and any explanations?

OA is C. Anyone up to say why E is not good?

Totally confused

Can anyone clearly state what the assumption in the argument is and how is the answer attacking the assumption?

Author says that to produce excellent researchers you need:
1- A drive to solve problems = dedication
2- the ability to identify the right questions to ask = creativity

Conclusion: If we(universities) are to produce good researchers, we need to focus on dedication and creativity and go beyond merely pouring information to students.

C says:
But the goal of our university is NOT to produce good researchers but to produce well-rounded individuals. Hence, there is no point in focusing in dedication and creativity and this would be the strongest objection to the author's claim

E is next best answer.
However, saying that there is harmed caused when you go beyond merely giving information to students does not give a reason as to how the focusing on dedication and creativity would not produce good researchers. For instance, despite there being harm caused to researchers, there could still be a good culture of dedication and creativity which would make good researchers. The point is we do not know which kind of "harm" is caused by giving more information and C more directly attacks the claim. Maybe someone would have a better reason to refute E...
