Several excellent candidates have been proposed for the presidency of United Wire, and each candidate would bring to the job different talents and experience.
Conclusion
Jones is best qualified to be the new president of UW.
Evidence
None of the other candidates for president of UW have Jones's unique set of qualifications.
Evaluate
Given That none of the other proposed candidates have J's unique set of qualifications,
How Could We Argue that someone else is equally or better qualified to be the new president?
It seems important that the conclusion is just "who is the most qualified", not necessarily . We can't just introduce other considerations that are possible negatives about Jones (she has exorbitant salary demands / she doesn't get along as well with other people).
So we can only look at qualifications vs. qualifications. Does J's qualifications have some advantage that we can offset with a disadvantage?
We're stuck with this one, very vague, premise that no one else has J's unique set.
Okay, does "unique set = best set"?
No other man has my unique set of facial features, but I definitely do not think I have the best set of facial features.
The other gap seems to be that we started by comparing Jones to all the other proposed candidates, but the conclusion seems to be saying Jones is best qualified, out of everyone.
So maybe we could object that even if J is best qualified out of the set of proposed candidates, there's someone equally/better qualified that isn't a proposed candidate.
Goal
Look for an answer saying "unique ≠ best", or one saying "best of the proposed ≠ best anywhere".
