Principle: When none of the fully qualified candidates for a new position at Arvue Corporation currently works for that company, it should hire the candidate who would be most productive in that position.

Conclusion

Arvue should not hire Krall for the new position

Evidence

Delacruz is a candidate and is fully qualified.

no fully qualified candidates → hire candidate currently work for company who'd be most productive

Evaluation

This looks like a rule that can't prove what we want. This rule only tells us a condition under which we should hire someone. It doesn't actually look like a rule that instructs us not to hire someone.

However, because it says that we should hire the most productive, that outcome implies that anyone who isn't the most productive shouldn't be hired (assuming we're only hiring one person to fill the position).

Goal

So we would want to know that there are no fully qualified candidates that work at the company, so that we trigger the rule, and then we would want to know that Krall isn't the most productive.

19.

Which one of the following, if true, justifies the above application of the principle?

  1. All of the candidates are

    Not Most Productive?

    With no fully qualified candidates working for Arvue, we'd move on to picking based on who's most productive, and this answer doesn't compare Krall vs Delacruz on that level.

  2. Of all the candidates who

    No In-House Candidates?

    If there aren't any fully qualified in-house candidates, then Delacruz would be our pick. But this answer doesn't reveal whether there are any fully qualified candidates who already work for Arvue.

    12% picked this

  3. Krall works for Arvue, but

    Krall Fully Qualified?

    If Krall is fully qualified (and if Delacruz is an outsider), then Krall might be the person they'd hire. We're not sure from this answer whether Delacruz also works for the company or whether Krall is fully qualified.

  4. Several candidates currently work for

    Other Candidates Fully Qualified?

    If those in-house candidates are fully qualified, then we won't even trigger this rule and reach the stage of analyzing who'd be most productive. But we don't know And this answer doesn't tell us who would win between Krall and Delacruz on that level. So there's no way to rule out Krall as the new hire.

    2% picked this

  5. Correct

    None of the candidates already

    Why this is right

    The first fact triggers our rule, since no fully qualified applicants (or un-fully qualified, apparently) work for the company. Once triggered, the rule says we have to pick the most productive, who is Delacruz. Hence, we have proven that we will not pick Krall.
