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.
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 ______ .
-
Amost ground collisions happen when ground crews are rushing to minimize the time a delayed plane spends on the ground
分析该选项
-
Ba ground collision typically occurs when there are no passengers on the airplane
分析该选项
-
Cthe additional training will focus on helping ground crews avoid those kinds of ground collisions that cause the most costly damage
分析该选项
-
Dthe $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
分析该选项
-
Emost ground collisions have been caused by the least experienced ground-crew members
