Some X-Ray Machines at Cleveland clinic require certain upgrades. However, the work of upgrading the 20 X-Ray Machines is difficult and mentally taxing. Physicians require X ray reports during the day, making it difficult for the X-Ray Machine technician to set aside time for upgrading each of the X-Ray Machines. Therefore, the most efficient time to upgrade the X-Ray Machines is between 10 p.m. and 8 a.m. when the X-Ray Machines
would be free.

Which of the following, if true, argues most strongly against the view that upgrades could be done more efficiently by scheduling them at night ?

A. X-Ray Machine technicians are generally paid the same when they work during the night than when they work during the day
B. Energy costs in hospitals are greatly lower at night than they are during the day.
C. More blackouts occur between midnight and eight o'clock in the morning than at any other time.
D. Mental alertness is lower in the late night than during the day, especially in people not accustomed to working at night.
E. Over the course of a year, hospital's X-Ray Machines will require periodical checks and upkeep
