First, break down the argument, starting with the conclusion:
- Conclusion: "something must discourage the people who would be the best-liked teachers from entering this profession"
- Support: teachers most often identified as the best-liked ones "possessed a personality type that constitutes 20 percent of the general public but only 5 percent of teachers"
Essentially, the desired personality type is underrepresented among teachers. After all, 20% of the general population has it, but only 5% of teachers do. The argument provides an explanation for this: something prevents these people from entering the teaching profession.
Which answer choice weakens the argument?
Quote:
A. People with the personality type constitute 5 percent of the medical profession.
Option (A) tells us that this personality type is ALSO underrepresented in the medical profession. That doesn’t impact the argument about
teachers at all
. We just don’t get any insight into why the teaching profession is so low on people with the personality type. (A) is out.
Quote:
B. People with the personality type constitute 5 percent of college students pursuing a degree in education.
Statement (B) actually would SUPPORT the argument. The fact that the personality type is already underrepresented in people studying to become teachers shows that people with this personality type don't choose to become teachers in the first place. Eliminate (B).
Quote:
C. Students of teachers with the personality type are intensely recruited for noneducational professions.
The argument is about the
teachers possessing a certain personality type. We do not really care about what their
students do in the future. We have no idea what kind of personality type they possess, it is not necessarily this "great" one the argument mentions.
So this statement doesn't have any impact on our conclusion. Eliminate (C).
Quote:
D. Students with the personality type are more likely to be liked by teachers than those with other personality types.
OK, here we at least talk about the people with this personality type. However, choice (D) still does not discuss the issue at hand.
These students are more liked by teachers -- great for them, I guess. But being liked by teachers does not necessarily imply that these students would become teachers themselves.
So again, the connection with the argument is very marginal at best. Eliminate (D).
Quote:
E. Teachers with the personality type are more likely to quit teaching than those with other personality types.
Statement (E) actually proposes an alternative explanation to the one proposed by the argument. It says that these teachers are more likely to
quit teaching, while the argument states that these teachers
must not have ENTERED the profession in the first place.
According to (E), the reason why teachers with such personality type are underrepresented is that they simply
quit teaching at some point. By offering this alternative reason for the situation discussed, statement (E) indeed weakens the argument.
Since no other option does that, (E) must be correct.
