"However, the researchers conclusion that attending graduate school at an early age improves ones likelihood of professional rise, is not entirely correct"
"Those who were found to be rapidly climbing the corporate ladder are
very competitive individuals and its their
competitiveness, which took them to graduate school at early age"
Researchers Argument
early grad= professional riseObjector Argument -
competitiveness of very competitive individuals = professional rise. The main driver is their competitiveness, not their early grad. Early grad is just a consequence of competitiveness.
Strengthen --- it was their competitiveness that equated to rapid professional rise. In order to strengthen you must strengthen the link/assumption. A- This suggests
performance in Quant and Verbal ability test=Competitiveness?
Quite the stretch in logic. Naturally gifted in these areas?
B. - At first glance this may look like it goes against the premise...however you would have to assume
greater challenges= did not rise rapidly. BUT the premise is always an undeniable fact and it's a "if true" statement. B would have to blatantly go against the premise and in this case, you can also see it another way....
The fact that the professionals have the advantage of early graduate education, despite the greater challenges faced (statement if true), climbed the corporate ladder rapidly (premise) because, according to the Objector, they were very competitive. Which is a vastly smaller leap than A. Directly strengthens the fact it was their "very competitiveness" nature that led to their rapid rise. I think it's important to note, competing could be shmoozing to your boss, playing the corporate game, learning the business better than others, putting in more time, strategically planning career path, being in the right place at the right time etc. Doesn't really matter what it is. As long as you're trying, you're competing. Can you get successive and rapid promotions without really trying, I guess? Extremely unlikely.
B isn't perfect by any means but its closest so far.
C. This compares grad pools of equal competitiveness and says they gain similar degree of improvement in leadership/interpersonal skills. So the assumption here is that lower competitiveness pools and higher competitiveness pools attained similar skills, respectively within their groups. There was no advantage over the same competitiveness level but different group. So the logical leap is to say that the early grad pool, which according to the argument is very competitive, rose rapidly due to none other than their competitive nature.
Bit of a longer leap than B. You kind of have to assume there isn't any other skills that would lead to rapid rise. Doesn't identify competitiveness as the sole reason for rapid rise. Leaves room for other skills.
D. Same bucket as A. Longer to complete education= less competitive? Stretch. Marginally strengthens it.
E. Opinion statement.
I would pick B.
EG would say A but the solution noted doesn't explain Competitiveness= ability test
Open to discuss.
