Programmer: We computer programmers at Mytheco are demanding raises to make our average salary comparable with that of the technical writers here who receive, on average, 20 percent more in salary and benefits than we do. This pay difference is unfair and intolerable. Mytheco executive: But many of the technical writers have worked for Mytheco longer than have many of the programmers. Since salary and benefits at Mytheco are directly tied to seniority, the 20 percent pay difference you mention is perfectly acceptable. Evaluating the adequacy of the Mytheco executive's response requires a clarification of which one of the following? ["how the Mytheco executive's salary compares with that of the programmers", 'how the average seniority of programmers compares with the average seniority of technical writers', 'whether any of the technical writers at Mytheco once worked as programmers at the company', 'whether the sorts of benefits an employee of Mytheco receives are tied to the salary of that employee']
