I'm a bit confused on this as well.

@AnkitM @ariella let's diagram the principle first:

"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."

no FQCCWA ==> HMPC
not HMPC ==> some FQCCWA

The application is:

"Arvue should not hire Krall for the new position, because Delacruz is a candidate and is fully qualified."

Notice that to conclude Arvue should hire someone, we need to invoke the sufficient condition of the principle, which is "none of the fully qualified candidates for a new position at Arvue Corporation currently works for that company."

This leads to the necessary condition, which is Arvue "should hire the candidate who would be most productive in that position."

Notice this is exactly what (E) does, it invokes the sufficient condition, i.e. none of the candidates already works for Arvue, and then tells us that the necessary condition would be Delacruz, i.e. the candidate who would be most productive in the new position.

Hope that helps! Please let us know if you have any other questions.
