Fremont: Simpson is not a viable candidate for chief executive of Pod Oil because he has no background in the oil industry.
Conclusion
I disagree (the fact that Simpson has no background in the oil industry doesn't prove he's not a viable CEO of Pod Oil).
In other words, someone with no background in the oil industry could still be a viable candidate for CEO of Pod Oil.
Evidence
An oil background is no guarantee of success; for example, the last CEO had an oil background and was terrible.
Evaluate
Galindo's first comment seems to imply that Fremont was thinking that . But Fremont certainly never argued that.
Fremont is probably thinking "an oil background" is a minimum requirement, not a sufficient guarantee of success.
Goal
Look for an answer pointing out that Galindo implicitly accuses F of a position that F never espoused (this is called Straw Man), or an answer that says "even if people with backgrounds in oil can still be crappy CEO's, it might still be true that people without backgrounds in oil can't be successful CEO's).
