146. The following appeared in a memo from the president of a chain of cheese stores located throughout the United States.

"For many years all the stores in our chain have stocked a wide variety of both domestic and imported cheeses. Last year, however, the five best-selling cheeses at our newest store were all domestic cheddar cheeses from Wisconsin. Furthermore, a recent survey by Cheeses of the World magazine indicates an increasing preference for domestic cheeses among its subscribers. Since our company can reduce expenses by limiting inventory, the best way to improve profits in all of our stores is to discontinue stocking many of our varieties of imported cheese and concentrate primarily on domestic cheeses."

147. The following appeared in a letter from a firm providing investment advice to a client.

"Homes in the northeastern United States, where winters are typically cold, have traditionally used oil as their major fuel for heating. Last year that region experienced 90 days with below-average temperatures, and climate forecasters at Waymarsh University predict that this weather pattern will continue for several more years. Furthermore, many new homes have been built in this region during the past year. Because of these developments, we predict an increased demand for heating oil and recommend investment in Consolidated Industries, one of whose major business operations is the retail sale of home heating oil."

148. The following appeared in a letter to the editor of a newspaper serving the villages of Castorville and Polluxton.

"Both the villages of Castorville and Polluxton have experienced sharp declines in the numbers of residents who pay property taxes. To save money and improve service, the two villages recently merged their once separate garbage collection departments into a single department located in Castorville, and the new department has reported few complaints about its service. Last year the library in Polluxton had 20 percent fewer users than during the previous year. It follows that we should now further economize and improve service, as we did with garbage collection, by closing the library in Polluxton and using the library in Castorville to serve both villages."

149. The following appeared in a memo from a budget planner for the City of Grandview.

"To avoid a budget deficit next year, the City of Grandview must eliminate its funding for the Grandview Symphony. Our citizens are well aware of the fact that while the Grandview Symphony Orchestra was struggling to succeed, our city government promised annual funding to help support its programs. Last year, however, private contributions to the Symphony increased by 200 percent, and attendance at the Symphony's concerts-in-the-park series doubled. The Symphony has also announced an increase in ticket prices for next year. Such developments indicate that the Symphony can now succeed without funding from city government and we can eliminate that expense from next year's budget. This action will surely prevent a budget deficit."

150. Yellow-legged frogs were once common in high-altitude lakes in the Sierra Nevada mountains, but they have become increasingly rare. Trout feed on tadpoles and young frogs. Few lakes in the Sierra Nevada had any trout in them until a hundred years ago. At that time, many lakes were stocked with trout for recreational fishing, and now trout are common in virtually all bodies of water in the Sierra Nevada. Researchers removed the trout from one lake, and the frog population soon quadrupled. Since frogs are capable of moving several miles over land, removing trout from just a few lakes is clearly the way to restore the frog population to its former levels.
