Q5, try deny test.  Deny C, we get "A nation that has the terms of its dealings with another action set by that nation can still be a world leader."  If so, this claim in the original passage "a nation that owes money to another nation cannot be world leader" will fall apart.  So, C is a necessary assumption of the passage.

Q6, Sims does metnion the issue of age: " so I will not comment on your youth and inexperience."  Therefore, B is out.

On the other hand, Smis didn't respond to Rotelle's claim that he was "too old to address effectively the difficult issues...", so E is correct.
