A reliable survey indicates that college graduates change employers

Question

A reliable survey indicates that college graduates change employers four times on average during the first ten years after college graduation. Therefore, in order to avoid employee turnover, business administrators in charge of hiring new employees should favor job applicants who obtained college degrees at least ten years earlier.

The advice about how to avoid employee turnover rests on which of the following assumptions?

(A) Employee turnover among businesses that hire employees without college degrees is greater than among businesses that hire only employees with college degrees.

(B) Job changes within the same company are less common than job changes from one employer to another.

(C) Employees who graduated from college at least ten years ago change employers less frequently on average than other employees.

(D) Most employees who leave their jobs do so upon either request or demand of their employers rather than by their own initiative.

(E) The survey excluded college graduates who interrupted their vocational careers to pursue advanced academic degrees.

The argument tells us that employees who graduated college less than 10 years ago, change employers 4 time on an average.
And it also says that hiring people who graduated over 10 years ago will reduce turnover. That only makes sense if those older graduates actually change employers less often - because what if graduates who graduated college more than 10 years ago actually change employers >4 times - then the conclusion will fail. 
That’s why (C) is required.

The statement begins with a term reliable survey, means the creditor the survey cannot be put into question. Then, the outcome of the survey - “  college graduates change employers four times on average during the first ten years after college graduation “.

So to avoid employee turn over, the business administrators should employ applicants who got graduated ten years earlier.

The comparison is between graduates (Less than 10 years) vs graduates (More than 10 years).

The advice about how to avoid employee turnover rests on which of the following assumptions?

(A) Employee turnover among businesses that hire employees without college degrees is greater than among businesses that hire only employees with college degrees.

With college degrees and without college degree comparison is not discussed here. The time period between completion of a degree and joining is the issue. Hence, wrong.

(B) Job changes within the same company are less common than job changes from one employer to another.

The comparison is made between inter company and intra company transfers. If, its intra company transfer, the term “ change of employers “ cannot be applied. Even though, larger companies with many sister concerns might have different company names for their service. But, that cannot be taken as change of employers.

(C) Employees who graduated from college at least ten years ago change employers less frequently on average than other employees.

This is the correct assumption. They believe those who graduated ten years earlier, might have completed the average 4 shifts of change before joining this company. Hence, lesser likelihood of changing employer.

(D) Most employees who leave their jobs do so upon either request or demand of their employers rather than by their own initiative.

This option speaks about an aspect of an employee leaving a job - like dismissal, termination etc. Hence, wrong.

(E) The survey excluded college graduates who interrupted their vocational careers to pursue advanced academic degrees.

This option is wrong, as it makes comparisons between the academic degrees.

Option C

OFFICIAL EXPLANATION

The correct answer is (C).

The argument fails to explicitly provide that employees who are at least ten years out of college change employers less frequently on average than other employees. This premise is essential to the argument’s conclusion, and choice (C) supplies this additional premise.
