To reduce the frequency of ground collisions, Innovair will begin giving its ground crews additional training, at an annual cost of $500, 000. Although this will cut the number of ground collisions by about half at best, the drop in repair costs can be expected to be much greater, since __ . Which of the following most logically completes the argument? In a typical year, Innovair's airplanes are involved in 35 collisions while parked or being towed in airports, with a resulting yearly cost of $1, 000, 000 for repairs.
A: most ground collisions have been caused by the least experienced ground-crew members
B: a ground collision typically occurs when there are no passengers on the airplane
C: the additional training will focus on helping ground crews avoid those kinds of ground collisions that cause the most costly damage
D: the $500, 000 cost figure for the additional training of ground crews includes the wages that those crews will earn during the time spent in actual training
Choose A, B, C or D as your solution.
