It is the policy of SubStop Sandwiches to give discretionary raises only to employees who demonstrate a strong commitment to their jobs and have worked at SubStop for more than six months. However, a state labor law requires SubStop to provide annual cost-of-living raises to all employees who have been continuously employed for at least six months. Last year, SubStop complied fully with its own policy and with the state’s labor laws. Yet, 2—and only 2—of SubStop Sandwiches’ 8 employees received any wage raise whatsoever last year.
If the information provided is true, which of the following must on the basis of it also be true about SubStop last year?
(A) Two of its employees demonstrated a strong commitment to their jobs.
(B) None of its employees received a discretionary raise.
(C) Six of its employees failed to demonstrate a strong commitment to their jobs.
(D) Two of its employees worked at SubStop continuously for at least six months.
(E) It claimed to provide wage raises in compliance with the state’s labor law but in fact did not.
SubStop complied with the state’s cost-of-living raise requirements. (The question stem stipulates that all information in the passage is true.) Therefore, the only explanation for giving either type of raise (discretionary or cost-of-living) to 2 employees last year is that they had worked for SubStop continuously for six months.
