The following appeared in a memo from a budget planner for the city of Grandview.
"It is time for the city of Grandview to stop funding the Grandview Symphony Orchestra. It is true that the symphony struggled financially for many years, but last year private contributions to the symphony increased by 200 percent and attendance at the symphony's concerts-in-the-park series doubled. In addition, the symphony has just announced an increase in ticket prices for next year. For these reasons, we recommend that the city eliminate funding for the Grandview Symphony Orchestra from next year's budget. We predict that the symphony will flourish in the years to come even without funding from the city."

The following appeared in a letter to the school board in the town of Centerville.
"All students should be required to take the driver's education course at Centerville High School. In the past two years, several accidents in and around Centerville have involved teenage drivers. Since a number of parents in Centerville have complained that they are too busy to teach their teenagers to drive, some other instruction is necessary to ensure that these teenagers are safe drivers. Although there are two driving schools in Centerville, parents on a tight budget cannot afford to pay for driving instruction. Therefore an effective and mandatory program sponsored by the high school is the only solution to this serious problem."

The following appeared in a recommendation from the planning department of the city of Transopolis.
"Ten years ago, as part of a comprehensive urban renewal program, the city of Transopolis adapted for industrial use a large area of severely substandard housing near the freeway. Subsequently, several factories were constructed there, crime rates in the area declined, and property tax revenues for the entire city increased. To further revitalize the city, we should now take similar action in a declining residential area on the opposite side of the city. Since some houses and apartments in existing nearby neighborhoods are currently unoccupied, alternate housing for those displaced by this action will be readily available."

A recent study reported that pet owners have longer, healthier lives on average than do people who own no pets. Specifically, dog owners tend to have a lower incidence of heart disease. In light of these findings, Sherwood Hospital should form a partnership with Sherwood Animal Shelter to institute an adopt-a-dog program. The program would encourage dog ownership for patients recovering from heart disease, which should reduce these patients' chance of experiencing continuing heart problems and also reduce their need for ongoing treatment. As a further benefit, the publicity about the program would encourage more people to adopt pets from the shelter. And that will reduce the incidence of heart disease in the general population.

The following appeared in a memo from the marketing director of Top Dog Pet Stores.
"Five years ago Fish Emporium started advertising in the magazine Exotic Pets Monthly. Their stores saw sales increase by 15 percent after their ads began appearing in the magazine. The three Fish Emporium stores in Gulf City saw an even greater increase than that. Because Top Dog Pet Stores is based in Gulf City, it seems clear that we should start placing our own ads in Exotic Pets Monthly. If we do so, we will be sure to reverse the recent trend of declining sales and start making a profit again."

The following appeared as part of an article in a Dillton newspaper.
"In an effort to bring new jobs to Dillton and stimulate the city's flagging economy, Dillton's city council voted last year to lower the city's corporate tax rate by 15 percent; at the same time, the city began offering generous relocation grants to any company that would move to Dillton. Since these changes went into effect, two new factories have opened in Dillton. Although the two factories employ more than 1,000 people, the unemployment rate in Dillton remains unchanged. The only clear explanation for this is that the new factories are staffed with out-of-town workers rather than Dillton residents."
Write a response in which you discuss one or more alternative explanations that could rival the proposed explanation and explain how your explanation(s) can plausibly account for the facts presented in the argument.
The following appeared in a memo from the owner 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, all of the five best-selling cheeses at our newest store were 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."

The following appeared in a letter to the editor of the Parkville Daily newspaper.
"Throughout the country last year, as more and more children below the age of nine participated in youth-league sports, over 40,000 of these young players suffered injuries. When interviewed for a recent study, youth-league soccer players in several major cities also reported psychological pressure exerted by coaches and parents to win games. Furthermore, education experts say that long practice sessions for these sports take away time that could be used for academic activities. Since the disadvantages outweigh any advantages, we in Parkville should discontinue organized athletic competition for children under nine."

The council of Maple County, concerned about the county's becoming overdeveloped, is debating a proposed measure that would prevent the development of existing farmland in the county. But the council is also concerned that such a restriction, by limiting the supply of new housing, could lead to significant increases in the price of housing in the county. Proponents of the measure note that Chestnut County established a similar measure ten years ago, and its housing prices have increased only modestly since. However, opponents of the measure note that Pine County adopted restrictions on the development of new residential housing fifteen years ago, and its housing prices have since more than doubled. The council currently predicts that the proposed measure, if passed, will result in a significant increase in housing prices in Maple County.

The following appeared as a letter to the editor of a national newspaper.
"Your recent article on corporate downsizing* in Elthyria maintains that the majority of competent workers who have lost jobs as a result of downsizing face serious economic hardship, often for years, before finding other suitable employment. But this claim is undermined by a recent report on the Elthyrian economy, which found that since 1999 far more jobs have been created than have been eliminated, bringing the unemployment rate in Elthyria to its lowest level in decades. Moreover, two-thirds of these newly created jobs have been in industries that tend to pay above-average wages, and the vast majority of these jobs are full-time."
*Downsizing is the process whereby corporations deliberately make themselves smaller, reducing the number of their employees.

The following appeared as a letter to the editor from a Central Plaza store owner.
"Over the past two years, the number of shoppers in Central Plaza has been steadily decreasing while the popularity of skateboarding has increased dramatically. Many Central Plaza store owners believe that the decrease in their business is due to the number of skateboard users in the plaza. There has also been a dramatic increase in the amount of litter and vandalism throughout the plaza. Thus, we recommend that the city prohibit skateboarding in Central Plaza. If skateboarding is prohibited here, we predict that business in Central Plaza will return to its previously high levels."

The following is a recommendation from the Board of Directors of Monarch Books.
"We recommend that Monarch Books open a café in its store. Monarch, having been in business at the same location for more than twenty years, has a large customer base because it is known for its wide selection of books on all subjects. Clearly, opening the café would attract more customers. Space could be made for the café by discontinuing the children's book section, which will probably become less popular given that the most recent national census indicated a significant decline in the percentage of the population under age ten. Opening a café will allow Monarch to attract more customers and better compete with Regal Books, which recently opened its own café."

The following is a recommendation from the personnel director to the president of Acme Publishing Company.
"Many other companies have recently stated that having their employees take the Easy Read Speed-Reading Course has greatly improved productivity. One graduate of the course was able to read a 500-page report in only two hours; another graduate rose from an assistant manager to vice president of the company in under a year. Obviously, the faster you can read, the more information you can absorb in a single workday. Moreover, Easy Read would cost Acme only $500 per employee—a small price to pay when you consider the benefits. Included in this fee is a three-week seminar in Spruce City and a lifelong subscription to the Easy Read newsletter. Clearly, Acme would benefit greatly by requiring all of our employees to take the Easy Read course."

The following appeared in a memorandum from the general manager of KNOW radio station.
"Several factors indicate that radio station KNOW should shift its programming from rock-and-roll music to a continuous news format. Consider, for example, that the number of people in our listening area over fifty years of age has increased dramatically, while our total number of listeners has declined. Also, music stores in our area report decreased sales of recorded music. Finally, continuous news stations in neighboring cities have been very successful. The switch from rock-and-roll music to 24-hour news will attract older listeners and secure KNOW radio's future."

The following appeared in a memo from the Board of Directors of Butler Manufacturing.
"During the past year, workers at Butler Manufacturing reported 30 percent more on-the-job accidents than workers at nearby Panoply Industries, where the work shifts are one hour shorter than ours. A recent government study reports that fatigue and sleep deprivation among workers are significant contributing factors in many on-the-job accidents. Therefore, we recommend that Butler Manufacturing shorten each of its work shifts by one hour. Shorter shifts will allow Butler to improve its safety record by ensuring that its employees are adequately rested."

The following appeared on the Mozart School of Music Web site.
"The Mozart School of Music should be the first choice for parents considering enrolling their child in music lessons. First of all, the Mozart School welcomes youngsters at all ability and age levels; there is no audition to attend the school. Second, the school offers instruction in nearly all musical instruments as well a wide range of styles and genres from classical to rock. Third, the faculty includes some of the most distinguished musicians in the area. Finally, many Mozart graduates have gone on to become well-known and highly paid professional musicians."

The following appeared in a business magazine.
"As a result of numerous complaints of dizziness and nausea on the part of consumers of Promofoods tuna, the company requested that eight million cans of its tuna be returned for testing. Promofoods concluded that the canned tuna did not, after all, pose a health risk. This conclusion is based on tests performed on samples of the recalled cans by chemists from Promofoods; the chemists found that of the eight food chemicals most commonly blamed for causing symptoms of dizziness and nausea, five were not found in any of the tested cans. The chemists did find small amounts of the three remaining suspected chemicals but pointed out that these occur naturally in all canned foods."

The following appeared in a memo from the vice president of a food distribution company with food storage warehouses in several cities.
"Recently, we signed a contract with the Fly-Away Pest Control Company to provide pest control services at our warehouse in Palm City, but last month we discovered that over $20,000 worth of food there had been destroyed by pest damage. Meanwhile, the Buzzoff Pest Control Company, which we have used for many years in Palm City, continued to service our warehouse in Wintervale, and last month only $10,000 worth of the food stored there had been destroyed by pest damage. Even though the price charged by Fly-Away is considerably lower, our best means of saving money is to return to Buzzoff for all our pest control services."

The following memorandum is from the business manager of Happy Pancake House restaurants.
"Butter has now been replaced by margarine in Happy Pancake House restaurants throughout the southwestern United States. Only about 2 percent of customers have complained, indicating that 98 people out of 100 are happy with the change. Furthermore, many servers have reported that a number of customers who ask for butter do not complain when they are given margarine instead. Clearly, either these customers cannot distinguish butter from margarine or they use the term 'butter' to refer to either butter or margarine. Thus, to avoid the expense of purchasing butter and to increase profitability, the Happy Pancake House should extend this cost-saving change to its restaurants in the southeast and northeast as well."

The following appeared in a memo at XYZ company.
"When XYZ lays off employees, it pays Delany Personnel Firm to offer those employees assistance in creating résumés and developing interviewing skills, if they so desire. Laid-off employees have benefited greatly from Delany's services: last year those who used Delany found jobs much more quickly than did those who did not. Recently, it has been proposed that we use the less expensive Walsh Personnel Firm in place of Delany. This would be a mistake because eight years ago, when XYZ was using Walsh, only half of the workers we laid off at that time found jobs within a year. Moreover, Delany is clearly superior, as evidenced by its bigger staff and larger number of branch offices. After all, last year Delany's clients took an average of six months to find jobs, whereas Walsh's clients took nine."

The following is a recommendation from the business manager of Monarch Books.
"Since its opening in Collegeville twenty years ago, Monarch Books has developed a large customer base due to its reader-friendly atmosphere and wide selection of books on all subjects. Last month, Book and Bean, a combination bookstore and coffee shop, announced its intention to open a Collegeville store. Monarch Books should open its own in-store café in the space currently devoted to children's books. Given recent national census data indicating a significant decline in the percentage of the population under age ten, sales of children's books are likely to decline. By replacing its children's books section with a café, Monarch Books can increase profits and ward off competition from Book and Bean."

The following appeared in a memo from the vice president of a company that builds shopping malls around the country.
"The surface of a section of Route 101, paved just two years ago by Good Intentions Roadways, is now badly cracked with a number of dangerous potholes. In another part of the state, a section of Route 40, paved by Appian Roadways more than four years ago, is still in good condition. In a demonstration of their continuing commitment to quality, Appian Roadways recently purchased state-of-the-art paving machinery and hired a new quality-control manager. Therefore, I recommend hiring Appian Roadways to construct the access roads for all our new shopping malls. I predict that our Appian access roads will not have to be repaired for at least four years."

The following appeared in an article written by Dr. Karp, an anthropologist.
"Twenty years ago, Dr. Field, a noted anthropologist, visited the island of Tertia and concluded from his observations that children in Tertia were reared by an entire village rather than by their own biological parents. However, my recent interviews with children living in the group of islands that includes Tertia show that these children spend much more time talking about their biological parents than about other adults in the village. This research of mine proves that Dr. Field's conclusion about Tertian village culture is invalid and thus that the observation-centered approach to studying cultures is invalid as well. The interview-centered method that my team of graduate students is currently using in Tertia will establish a much more accurate understanding of child-rearing traditions there and in other island cultures."

"In a controlled laboratory study of liquid hand soaps, a concentrated solution of extra strength UltraClean hand soap produced a 40 percent greater reduction in harmful bacteria than did the liquid hand soaps currently used in our hospitals. During our recent test of regular-strength UltraClean with doctors, nurses, and visitors at our hospital in Worktown, the hospital reported significantly fewer cases of patient infection (a 20 percent reduction) than did any of the other hospitals in our group. Therefore, to prevent serious patient infections, we should supply UltraClean at all hand-washing stations, including those used by visitors, throughout our hospital system."
