For 20 years all applicants for jobs as technicians at EquipCorp were required to demonstrate that they could operate and repair the machinery that was central to EquipCorp's manufacturing business. Now, however, that particular machinery is obsolete, and very different machinery fills the central role. Therefore, the old requirement is no longer a useful method for evaluating whether applicants for jobs as technicians at EquipCorp have the skills necessary for the job.
Which of the following, if true, most strengthens the argument?
(A) The machinery that is now obsolete was used by a large number of manufacturing companies before it became obsolete.
(B) Among the people already holding jobs as tech-nicians at Equip Corp, those who are most skillful at operating the new machinery had been some of the least skillful at operating the old machinery
(C) Most people applying for jobs as technicians today have much broader skills than did people applying for jobs as technicians 20 years ago.
(D) The skills required to operate and repair the obsolete machinery are useful in operating and maintaining many other types of machinery at EquipCorp that are not obsolete.
(E) Much of the machinery that EquipCorp now uses in manufacturing is very likely to become obsolete within the next 20 years.
