Second Premise : " Only one quarter invest in third-party background check services, while the remainder rely
solely on references " . Note here, the author does not question the credibility of the references. He just points out a fact that some employers do not utilize a process.
Conclusion : "Clearly
most employers do not value an impartial assessment of a candidate’s background"
The imp thing is to identify the missing link between the premise and the conclusion. The premise says that most employers do not utilize one practice and the author concludes that most employers do not value impartial assessment. There is no given relationship that suggests what leads to impartial assessment. We need an option that links the premise with the conclusion.
"B. A candidate’s self-selected references sometimes provide incomplete or untrue information regarding their experience with a candidate."
This still does not provide any information about what leads to impartial assessment.
Negating the option : A candidate’s self-selected references none of the times provide incomplete or untrue information. That is, the references provide correct inf all the time.
Now can the conlcusion still holds true? Yes it can.We should not assume that credible references means impartial assessment. There could be any no of factors that lead to impartial assessment. Because there is no relationship mentioned between credibility of references and impartial assessment this is not an assumption required for conlcusion to hold true.
"D. An employer interested in an impartial assessment of a candidate’s background will use a third-party background check service."
This fills that missing gap. If it is true that impartial assessment of a candidate’s background can only be done using third-party background check service, then the author can conclude that since most employers don't use a third-party background check service, most employers do not value an impartial assessment.
We can double check by negating the choice : An employer interested in an impartial assessment of a candidate’s background WILL NOT use a third-party background check service.
This breaks the conclusion as it is already given that 3/4th of employers don't use third-party background check service and thus we can say that most( greater than 50%) do value an impartial assessment of a candidate’s background.
