A particular company makes a system that is installed in the engine block of a car and, if that car is stolen, relays the car’s location to police via satellite. The recovery rate of stolen cars with this device is ninety percent. This system helps everyone because it is impossible for a thief to tell which cars it is installed on. For these reasons, insurance companies try to encourage customers to get this system by offering lower rates to those who have the system. Competing systems include brightly colored steel bars that attach to the steering wheel and loud alarms that go off when the car is tampered with. These systems simply encourage thieves to steal different cars, and when cars with these devices are stolen, the police rarely recovery them.
Which of the following is the most logical conclusion to the author’s premises?
(A) Insurance companies should give the same discount to car owners that have any protective system because their cars are less likely to be stolen.
(B) The police shouldn’t allow car owners to install the loud sirens on their cars because everyone simply ignores the sirens anyway.
(C) Car owners with the system that relays location to the police should prominently advertise the fact on the side window of their cars.
(D) Thieves should simply steal the cars with loud alarms or bright steel bars because those cars probably wouldn’t also have the more effective system installed.
(E) Insurance companies should give less of a discount, or no discount at all, to the siren and steering wheel systems because they aren’t as effective as the relay system.
