The conclusion of the argument is the following:
Thus, organizations that are recruiting from within for leadership positions can increase the number of potentially strong performers in their candidate pool by actively seeking out candidates from among the introverted people in the organization.That conclusion is supported by all the information that precedes it:
In most large organizations, the majority of people who end up in leadership positions are extroverted. These people are likely to actively seek leadership positions and make themselves known when such positions are available. When an organization is looking for internal candidates to fill a leadership position, choosing only from among these extroverted people necessarily excludes many other candidates who, for any number of reasons, do not put themselves forward.We see that the point of the argument is that people who are not extroverted do not "make themselves known when such positions (leadership positions) are available." So, "when an organization is looking for internal candidates to fill a leadership position," only the extroverted people are considered. Thus, the consultant (the author) concludes that "organizations that are recruiting from within for leadership positions" will do better if they seek out introverted candidates, who would not have otherwise been in candidate pools.
The correct answer will provide additional support for the conclusion.
A. A greater proportion of qualified candidates for leadership positions are extroverted than are introverted.If anything this statement goes against the conclusion by indicating that most qualified candidates are extroverted people. If most qualified candidates are extroverted, then maybe actively seeking out introverted candidates won't do organizations much good.
So, while this choice does not prove the conclusion incorrect, it certainly doesn't provide additional support for the conclusion of the argument.
Eliminate.
B. Among people in leadership positions, the proportion who are introverted is approximately equal to the proportion who are extroverted.Notice that, if anything, what this choice says goes against what the argument says. After all, if it is true that "among people in leadership positions, the proportion who are introverted is approximately equal to the proportion who are extroverted," then introverted people are getting into leadership positions. So, maybe organizations don't have to actively seek out introverted candidates to get introverted people the process of recruiting for leadership positions.
That said, the argument does say the following:
In most large organizations, the majority of people who end up in leadership positions are extroverted.So, this choice is about a topic, "people in leadership positions" in general, that is different from the topic of the argument, "people who end up in leadership positions" in "large organizations."
In any case, what this choice says certainly doesn't support the conclusion of the argument.
Eliminate.
C. Some qualified candidates who are introverted will actively seek leadership positions when they become available.The conclusion of the argument is based on the idea that introverted candidates will NOT actively seek out leadership positions. It's for that reason that the consultant recommends that organizations actively seek out introverted candidates.
So, if anything, the fact presented by this choice, that some introverted people WILL actively seek out leadership positions is a reason why organizations would NOT have to seek out introverted candidates.
Now, this choice is about "some qualified candidates who are introverted." So, it doesn't directly conflict with what the argument says, "the majority of people who end up in leadership positions are extroverted. These people are likely to actively seek leadership positions and make themselves known when such positions are available."
All, the same the fact that "some qualified candidates who are introverted will actively seek leadership positions" is certainly not a reason for organizations to actively seek out introverted candidates.
Eliminate.
D. Organizations tend to prefer internal candidates when recruiting for leadership positions.The conclusion of the argument is about what an organization can do when it "is looking for internal candidates to fill a leadership position." So, this choice may explain WHY the topic of the passage is interesting to a consultant.
However, the fact stated by this choice does not mean that organizations can increase the number of potentially strong performers in their candidate pool by actively seeking out candidates from among the introverted people in the organization. After all, the fact that "organizations tend to prefer internal candidates" does not mean that they can find more internal candidates by seeking out introverted candidates.
Eliminate.
E. On average, extroverted people in leadership positions perform no better than introverted people do.This choice is a reversed way of saying that introverted people in leadership positions perform at least as well as extroverted people do.
So, it provides additional support for the conclusion that "organizations can increase the number of potentially strong performers in their candidate pool by actively seeking out candidates from among the introverted people" by providing reason to believe that introverted people are indeed "potentially strong performers." After all, if introverted people in leadership positions perform at least as well as extroverted people do, then we have reason to believe that introverted people actively sought out by organizations may perform strongly in leadership positions.
So, the correct answer is
