Question

In Kravonia, the average salary for jobs requiring a college degree has always been higher than the average salary for jobs that do not require a degree. Over the last few years, the number of Kravonians enrolled in college has been growing steadily. Therefore, the number of Kravonians entering the job market who have at least the qualification of a college degree will eventually be significantly higher than it has been over the last few years.

Which of the following, if true, most seriously weakens the argument?

(A) Kravonians with more than one college degree earn little more, on average, than do Kravonians with only one college degree

(B) The average number of years Kravonian college students remain enrolled before completing a degree has been increasing over the past several years.

(C) Despite the increase in the number of Kravonians attending college, the percentage of the population attending college is lower in Kravonia than in most other countries.

(D) In recent years, employers have been requiring college degrees for workers in jobs that were previously performed successfully by Kravonians who did not have college degrees.

(E) For many years, employers in Kravonia have had difficulty finding enough college graduates to fill the high-paying jobs that were available.

Answer 1

The average number of years Kravonian college students remain enrolled before completing a degree has been increasing over the past several years.

Option B is correct

Step-by-step explanation:

This one notes that years of enrolment for Kravonian students have been increasing over the past few years. As it has done for the last couple of years, the increase in enrolment will therefore have little effect on "Kravonians entering the labor market with a college degree."

Option A : Number of college degrees is clearly out of scope.

Option C : Percentage of population attending college in other countries is clearly out of scope.

Option D : Strengthens the argument.

Option E : Irrelevant
