GMATNinjaCould you please help with option D. how does 50% correspond to large proportion ?
Really struggling to pick this option as correct one.
The question asks us which answer choice "most strongly supports" the expectation that the plan will largely eliminate losses from theft. So we don't need to prove
without a doubt that the plan will have this result. Instead, we just need to choose the answer choice that supports the plan more than the other answer choices do.
I agree that we aren't provided with an exact definition of "large proportion." What we
do know is that the device will be installed in the 50% of trucks with the most valuable cargo. From a thief's perspective, this proportion seems pretty dang high -- if the thief targets this company, he/she has a 50% chance of choosing a truck with one of the devices installed. The information in (D) supports the company's expectation, even if there is a bit of doubt about the exact definition of "large proportion."
So, how do the other answer choices stack up?
Quote:
A) For thieves, a cargo is valuable only if it is easy for them to dispose of profitably.
There is nothing to suggest how easy it is to dispose of the company's cargo, or whether that is impacted at all by the tracking devices.
Eliminate (A).
Quote:
B) Some insurance companies charge less to insure cargoes transported in trucks protected by the device.
The company owner expects that installing the devices should "largely eliminate losses
from theft." Insurance rates are an entirely different cost, so (B) doesn't provide any information to support the owner's argument.
(B) is out.
Quote:
C) Most stolen trucks are eventually found, but unless a stolen truck is found very soon after it is taken, the likelihood that the trucking company will recover any of its cargo is very low.
The passage tells us that "the recovery rate for stolen cargo in trucks equipped with the device is impressive," but doesn't tell us
how quickly the trucks are found. It's possible that the thieves can offload the cargo well before the trucks are found, even if the tracking devices are installed.
Get rid of (C).
Quote:
E) The manufacturer of the device offers a five-year warranty on each unit sold, a longer warranty than any that is offered on any competing antitheft device.
Like (B), (E) gives us information about a completely different potential cost. The company owner cares specifically about eliminating loss from theft. A longer warranty has no impact on loss from theft, so (E) can't be the answer.
Because there are strong reasons to eliminate every answer except (D), (D) is the option that "most strongly supports" the company owner's expectations.
I hope that helps!
