A study of recent Pemberton College graduates found that those whose daily class schedules began before 10:00am began their careers with salaries that were nearly 20% higher than their counterparts whose class schedules began later in the day. Clearly those self-disciplined enough to wake up early for classes are seen as more employable than those who are unwilling to wake up early.

Which of the following, if true, would most weaken the argument above?


A. At Pemberton College, the majors for which average starting salaries are the highest are finance and engineering, each of which has core classes that are only offered at 8:30 and 9:30am.

B. Many lucrative careers, such as those in technology and graphic design, allow employees to begin their workdays at an hour of their choosing.

C. Many Pemberton College students pay their tuition by working part-time jobs that require extensive evening hours.

D. The dining halls at Pemberton College only serve breakfast until 10:00am on days when classes are in session.

E. Pemberton College’s career center only offers on-campus interview sessions in the mornings, so that students’ afternoons are free for extracurricular activities and part-time employment.

OA: A
Premise: Pemberton College graduates found that those whose daily class schedules began before 10:00am began their careers with salaries that were nearly 20% higher than their counterparts whose class schedules began later in the day.

Conclusion :those self-disciplined enough to wake up early for classes are seen as more employable than those who are unwilling to wake up early.

Correct option should show another reason for students,whose classes began before 10 a.m., getting higher paying jobs
Option A does that.

Stimulus :
Cause --> Waking up early
Effect --> Career with higher salary
Weakener option must show the causal relationship otherwise.

A. At Pemberton College, the majors for which average starting salaries are the highest are finance and engineering, each of which has core classes that are only offered at 8:30 and 9:30am. --> Correct, reverses the cause and effect, and weakens the argument

Hence, A.

Boil it down - those self-disciplined enough to wake up early for classes are seen as more employable than those who are unwilling to wake up early.
Type - weaken

A. At Pemberton College, the majors for which average starting salaries are the highest are finance and engineering, each of which has core classes that are only offered at 8:30 and 9:30am.- Correct - self-dicipline to wake up early is not the reason BUT the choice of major(engineering and finance) is the alternate cause here.

B. Many lucrative careers, such as those in technology and graphic design, allow employees to begin their workdays at an hour of their choosing. - Irrelevant - The conclusion talks about waking up early for classes and this statement talks about flexibility of timings during employment


C. Many Pemberton College students pay their tuition by working part-time jobs that require extensive evening hours. - Irrelevant

D. The dining halls at Pemberton College only serve breakfast until 10:00am on days when classes are in session. - Irrelevant

E. Pemberton College’s career center only offers on-campus interview sessions in the mornings, so that students’ afternoons are free for extracurricular activities and part-time employment.- Irrelevant

Answer A

VERITAS PREP OFFICIAL SOLUTION:



When the conclusion of a Weaken question is an explanation of some sort (here "the reason for these salary statistics is likely self-discipline"), your radar for correlation-vs.-causation should be on high alert - the right answer is likely an alternative explanation for that fact ("no, it's that these early risers are self-disciplined, it's that something else causes the salary difference.")

Here choice (A) supplies that alternative explanation: if the majors that lead to the highest salaries are those that require earlier classes, then the schedule - not the self-discipline - is the cause. Choice (A) is therefore correct.

Among the other choices:

(B) attempts to weaken the facts given in the argument ("hey but some lucrative careers don't require you to get up early") but remember that in Critical Reasoning you're stuck with the facts - the only thing you can attack is the conclusion. So here the only thing "attackable" is the explanation for the higher salaries for those with earlier classes, not the fact that those with earlier classes end up, on average, with higher salaries.

(C) misses the goal of the argument altogether. Whether some students stay up late working to pay tuition is immaterial to the facts that those with early classes end up with higher salaries on average.

(D) is also out of the scope of the argument/conclusion - if anything it might strengthen the general idea that lower salaries are a result of low self-discipline (if you can't get out of bed for either class or breakfast what's wrong with you?!) but even that is a loose connection.

And (E) misses the scope of the argument by replacing early classes with early interviews; the argument is about classes, so this choice misses the mark.
