Manufacturers of inkjet printers earn most of their profits from the sale of ink cartridges rather than from the sale of the printers. The PRQ Company's profits have declined in recent years because other manufacturers are selling ink cartridges compatible with PRQ printers at a lower price than PRQ can match. PRQ is responding by designing a printer that will only accept a new specially designed PRQ cartridge, which will sell for the same price as its current ink cartridges. The company projects that the new printer will create a surge in sales of the new compatible cartridges.
Which of the following, if true, would strengthen the projection that PRQ's plan will result in an increase in its cartridge sales?
(A) Sales of printers are expected to drop within the next year, but then increase over five years.
(B) Another printer manufacturer recently announced a plan to manufacture a printer that is only compatible with its own cartridges.
(C) First time buyers of printers will generally buy the least expensive model.
(D) Consumers showed a strong preference for PRQ's newly designed printer in several test markets.
(E) PRQ's engineering and design division is studying methods of manufacturing printer cartridges at a lower cost.
