In January 1992, the Sylvanic Exterminator Service of Salem County began a new service concentrating on the removal of bats, rats, and mice. Revenue increased twofold by the end of the year. However, since 1991 more people in Salem County have been taking care of their extermination problems on their own, and the extermination industry’s revenues have been dropping because of it. Sylvanic Exterminator Service has reported no such loss in revenue.Which one of the following statements, if true, would best explain the above paradox?
A]The Sylvanic Exterminator Service was audited in 1992 and has had to be extremely careful with its bookkeeping ever since.
B]In 1990, Sylvanic upgraded all of its poison sprayers, incurring a debt which will not be paid off until 1998.
C]People would rather take care of the pest problems themselves because it is less expensive.
D]The bat, rat, and mouse populations of Salem County have increased significantly since 1991.
E] The Sylvanic Exterminator Service’s new pest service has compensated for the losses it has been experiencing in the rest of its services.
