Only D stands close after taking 5 minutes.
A wrote:
(A) An employee of the federal government who earns a Master's Degree can expect a larger jump in his or her lifetime earnings than can a businessperson who earns a Master's Degree.
Here the comparison is made between two different job categories
B wrote:
(B) A community college will raise the salary of a professor with a Ph.D by a substantial amount and lower the salary of a colleague who did not receive a Ph.D solely to make her believe that her financial commitment to her Ph.D was worthwhile.
This is not in scope - the passage does not quote about lowering of salary
C wrote:
(C) A wholesaler who takes self-guided distance learning courses during his free time will build income and skills more effectively than a wholesaler who cuts back on his working hours in order to take community college courses.
How the income skills are build are out of scope, only after the person completed education we need to consider.

(D) A government employee with a bachelor's degree who returns to school to receive an advanced degree will see a rise in income proportionally similar to the rise in income experienced by a university employee with a bachelor's degree who returns to school to receive an advanced degree.
This is the correct answer as it compares the similar increase in income
E wrote:
(E) A businessperson with an advanced degree will both earn more money and be more proficient at his or her job than will a teacher with an advanced degree, regardless of the amount of on-the-job training held by either person.
Again this answer choice compares two different job categories.
