Trucking company owner: Theft of trucks containing valuable cargo is a serious problem. A new device produces radio signals that allow police to track stolen vehicles, and the recovery rate for stolen cargo in trucks equipped with the device is impressive. The device is too expensive to install in every truck, so we plan to install it in half of our trucks. Using those trucks for the most valuable cargo should largely eliminate losses from theft.
P : Device help to recovery the stolen cargo in trucks equipped with the device
P : The device will be installed in half of the trucks since it is expensive
C : Using trucks with device in transporting most valuable cargo will eliminate losses from theft.
Which of the following, if true, most strongly supports the trucking company owner’s expectation about the results of implementing the plan?
A. For thieves, a cargo is valuable only if it is easy for them to dispose of profitably.
-> Regardless of the device, the cargo in the truck will still be valuable for thieves. Thus this information neither supports nor weakens the argument.
B. Some insurance companies charge less to insure cargoes transported in trucks protected by the device.
-> Lower charge from insurance companies will provide another reason to install the device. However, this information does not directly touch the relation between installing the device and eliminating losses from theft.
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 premise has noted that device helps to recover stolen cargo. Thus this information does not weaken nor strengthen the argument. Moreover, still 50% of the trucks will not have devices and if stolen, cargos inside those trucks will be lost. The objective of the company's representative is to eliminate losses from theft not reducing. Thus this answer choice cannot be the answer.
D. Thieves generally avoid trucks belonging to trucking companies that are known to have installed the device in a large proportion of their trucks.
-> Correct. By installing 50% of trucks with most valuable cargo, thieves will gradually get to know that the truck of the company has the device equipped, thus avoid stealing trucks from the company.
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.
-> Warranty is not the concern in this question.
