QUESTION

If Robin’s statements are all true, which of the following must also be true?

A) If the organization is forced to relocate its offices next year, then the number of telecommuters must be fewer than 600.
B) If the number of telecommuters is more than 600, then the organization will be forced to either move its offices or build an extension.
C) The organization cannot build an extension and move its office at the same time.
D) If the number of telecommuters is fewer than 600, then the organization will be forced to either move its offices or build an extension.
E) The potential cost saving from telecommuting is greater than the potential cost saving from job sharing.

ANSWER

Answer: A
Explanation: A) Robin says that getting 600 people to telecommute would avoid the moving/building extension problem. So if Robin is correct and the organization still has that problem, then, as Choice A points out, fewer than 600 people must be telecommuters. Six hundred telecommuters would have fixed the problem, and so if the problem isn’t fixed, there can’t be 600 telecommuters. Choice B is impossible because 600 telecommuters would have solved the problem. Choice C is possible but not definite. Either approach would solve the overflow problem, but that’s no reason to be sure that they can’t both happen. Choice D: 600 telecommuters would solve the overflow problem, but there could be other ways to solve the overflow problem. Telecommuting was a sufficient solution, but that doesn’t mean that it’s the only solution. Choice E: Robin never compares these two sources of savings.
