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 ______________

A) most ground collisions happen when ground crews are rushing to minimize the time a delayed plane spends on the ground.
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.
E) most ground collisions have been caused by the least experienced ground-crew members

Even though the additional training, at an annual cost of \$500,000 , will reduce the number of ground collisions by about half at best , the drop in repair cost can be expected to much greater --
Pre- thinking - maybe the new training will focus on the collisions that cause the most costly damage .

C) the additional training will focus on helping ground crews avoid those kinds of ground collisions that cause the most costly damage. Correct answer

Yearly repair cost = \$1,000,000
Annual Training cost = \$500,000

Suppose there were 10 collisions that would cost \$1,000,000. Out of those 3 cost \$300K each and rest 7 collisions cost \$100k.
If you say training would only CUT the number of collisions by HALF (i.e. instead 10 collision now there are only 5 collisions) AT BEST, the drop is repair cost expected to be MUCH GREATER. Now the questions asks HOW?? we need to tell the reason how it is possible. This is only possible if those 5 collisions which you saved were those which included those 3 collisions which cost \$300k each.

A) most ground collisions happen when ground crews are rushing to minimize the time a delayed plane spends on the ground.
How do we know that the delayed plane would have the costly collision? Out of scope choice it is.

B) a ground collision typically occurs when there are no passengers on the airplane.
Out of scope. We don’t want to know when and how the collision occurs. Argument is talking about number of collision and cost related to them.

C) the additional training will focus on helping ground crews avoid those kinds of ground collisions that cause the most costly damage.
Yes, if training helps save the MOST COSTLY collisions then even if you reduce the collisions by HALF AT THE BEST, you would end up saving the cost GREATLY.

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.
Can we even compare the cost of Collison with the wages of crews?? There is a huge difference. Irrelevant. BIG TRAP bdw.

E) most ground collisions have been caused by the least experienced ground-crew members
Fine, if 6 out 10 collisions were caused by the least experience members then there are two things to be noted here:
1. Training cannot increase your experience.
2. If you think training can help you save those 6 collisions (actually you can save only 5 s per the argument) then we are not sure if those 6 collisions would include the 6 collisions that cost \$300k each.

The reason has to have something to do with the repair costs associated with the collisions that are expected to still happen. Specifically, the repair costs for those collisions have to be lower than average. Other words, the repair costs for the avoided collisions have to be higher than average. Answer choice C fits the reasoning.

OG 2017 New Question

Explaination :-

A) most ground collisions happen when ground crews are rushing to minimize the time a delayed plane spends on the ground.
WRONG :- Irrelevant information. Not connected to the repair cost in any manner.

B) a ground collision typically occurs when there are no passengers on the airplane.
WRONG:- Irelevaant to the argument at hand. No connection to reduce damage repair cost or training.

C) the additional training will focus on helping ground crews avoid those kinds of ground collisions that cause the most costly damage.
CORRECT:- Total damage because of collision =1 million, Training cost= half million.
Total expense to the company 1 million + half million ( IF THE TRAINING IS USELESS)
But training is helpful and prevents HALF THE NUMBER OF the most expensive damages. The reaming half collision cost only 10K.
Money Lost = half million in training + 10 K ( i.e.:-Money lost to collision)
NET MONEY SAVE = 1million -( Half million + 10 K )= almost half million

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.
WRONG :- Tempting but Incorrect. If someone would say that at least the company is saving money on training by clubbing the salary in training expense. But can the salary of a few crew members be half a million. (Damage - Training cost) NOT LIKELY.

E) most ground collisions have been caused by the least experienced ground-crew members
WRONG :- Agreeable but ultimately incorrect. If the damage in such accident is only 20 K , then there is no logic behind this argument. We are not concerned about who gets the training or who has caused more accidents. What we are concerned with is - TO GIVE TRAINING AND REDUCE DAMAGE REPAIR COST.

Is below approach correct?
(Simplifying nos in Q stem)
Innovair: I
Say I spend \$5 in training ground crews whereas the repair cost is \$10
(for 35 planes), then D is a bit out of scope then even if we know that the
training costs includes wages earned by ground crew during training, we can
not establish any relationship with whether repairs will come down more exponnently

adkikani, I think you are on the right track here...

The collisions cost Innovair \$1,000,000 per year. If all collisions cost about the same, then cutting collisions in half should cut the cost in half (bringing it down to about \$500,000).

The new training is going to cost \$500,000 and, at best, it is going to cut collisions in half. If all collisions cost about the same, then that new training will only save \$500,000 AT BEST. So why would we spend \$500,000 on training if it will only save us \$500,000 or less? At best, we'll break even, and we might even lose money!

As for choice (D), even though the wages are part of that \$500,000 training expense, we'll have the same problem if the training is only going to save us \$500,000 or less.

But what if all collisions are not created equal? In other words, what if some kinds of collisions are more costly than others? In that case, if we can eliminate most of THOSE kinds of costly collisions, then cutting collisions by half might save substantially more than \$500,000.

If Innovair focuses its training on avoiding those kinds of costly collisions, they can expect to save substantially more than \$500,000. So choice (C) is correct.
