The following appeared in a memo from New Ventures Consulting to the president of HobCo, Inc., a chain of hobby shops.
"Our team has completed its research on suitable building sites for a new HobCo hobby Shop in the city of Grilldon. We discovered that there are currently no hobby shops in southeastern Grilldon. When our researchers conducted a poll of area residents, 88 percent of those who responded indicated that they would welcome the opening of a hobby shop in southeastern Grilldon. Grilldon is in a region of the nation in which the hobby business has increased by 300 percent during the past decade. In addition, Grilldon has a very large population of retirees, a demographic with ample time to devote to hobbies. We therefore recommend that you choose southeastern Grilldon as the site for your next HobCo Hobby Shop. We predict that a shop in this area will draw a steady stream of enthusiastic new HobCo customers."

The following appeared in a memo to the board of directors of a company that specializes in the delivery of heating oil.
"Most homes in the northeastern United States, where winters are typically cold, have traditionally used oil as their major fuel for heating. Last heating season, that region experienced 90 days with below-normal temperatures, and climate forecasters predict that this weather pattern will continue for several more years. Furthermore, many new homes are being built in the region in response to recent population growth. Because of these trends, we can safely predict that this region will experience an increased demand for heating oil during the next five years."

Nature's Way, a chain of stores selling health food and other health-related products, is opening its next franchise in the town of Plainsville. The store should prove to be very successful: Nature's Way franchises tend to be most profitable in areas where residents lead healthy lives, and clearly Plainsville is such an area. Plainsville merchants report that sales of running shoes and exercise clothing are at all-time highs. The local health club has more members than ever, and the weight training and aerobics classes are always full. Finally, Plainsville's schoolchildren represent a new generation of potential customers: these schoolchildren are required to participate in a fitness-for-life program, which emphasizes the benefits of regular exercise at an early age.

The following appeared in a letter from a homeowner to a friend.
"Of the two leading real estate firms in our town-Adams Realty and Fitch Realty-Adams Realty is clearly superior. Adams has 40 real estate agents; in contrast, Fitch has 25, many of whom work only part-time. Moreover, Adams' revenue last year was twice as high as that of Fitch and included home sales that averaged $168,000, compared to Fitch's $144,000. Homes listed with Adams sell faster as well: ten years ago I listed my home with Fitch, and it took more than four months to sell; last year, when I sold another home, I listed it with Adams, and it took only one month. Thus, if you want to sell your home quickly and at a good price, you should use Adams Realty."

Twenty years ago, Dr. Field, a noted anthropologist, visited the island of Tertia. Using an observation-centered approach to studying Tertian culture, he concluded from his observations that children in Tertia were reared by an entire village rather than by their own biological parents. Recently another anthropologist, Dr. Karp, visited the group of islands that includes Tertia and used the interview-centered method to study child-rearing practices. In the interviews that Dr. Karp conducted with children living in this group of islands, the children spent much more time talking about their biological parents than about other adults in the village. Dr. Karp decided that Dr. Field's conclusion about Tertian village culture must be invalid. Some anthropologists recommend that to obtain accurate information on Tertian child-rearing practices, future research on the subject should be conducted via the interview-centered method.

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 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 appeared in a memo from the new vice president of Sartorian, a company that manufactures men's clothing.
"Five years ago, at a time when we had difficulty obtaining reliable supplies of high-quality wool fabric, we discontinued production of our popular alpaca overcoat. Now that we have a new fabric supplier, we should resume production. Given the outcry from our customers when we discontinued this product and the fact that none of our competitors offers a comparable product, we can expect pent-up consumer demand for our alpaca coats. This demand and the overall increase in clothing prices will make Sartorian's alpaca overcoats more profitable than ever before."

The vice president of human resources at Climpson Industries sent the following recommendation to the company's president.
"A recent national survey found that the majority of workers with access to the Internet at work had used company computers for personal or recreational activities, such as banking or playing games. In an effort to improve our employees' productivity, we should implement electronic monitoring of employees' Internet use from their workstations. Using electronic monitoring software is the best way to reduce the number of hours Climpson employees spend on personal or recreational activities. We predict that installing software to monitor employees' Internet use will allow us to prevent employees from wasting time, thereby increasing productivity and improving overall profits."

The following appeared in an e-mail sent by the marketing director of the Classical Shakespeare Theatre of Bardville.
"Over the past ten years, there has been a 20 percent decline in the size of the average audience at Classical Shakespeare Theatre productions. In spite of increased advertising, we are attracting fewer and fewer people to our shows, causing our profits to decrease significantly. We must take action to attract new audience members. The best way to do so is by instituting a 'Shakespeare in the Park' program this summer. Two years ago the nearby Avon Repertory Company started a 'Free Plays in the Park' program, and its profits have increased 10 percent since then. If we start a 'Shakespeare in the Park' program, we can predict that our profits will increase, too."

The following is a letter to the editor of an environmental magazine.
"Two studies of amphibians in Xanadu National Park confirm a significant decline in the numbers of amphibians. In 1975 there were seven species of amphibians in the park, and there were abundant numbers of each species. However, in 2002 only four species of amphibians were observed in the park, and the numbers of each species were drastically reduced. One proposed explanation is that the decline was caused by the introduction of trout into the park's waters, which began in 1975. (Trout are known to eat amphibian eggs.)"

The following memorandum is from the business manager of Happy Pancake House restaurants.
"Recently, butter has been replaced by margarine in Happy Pancake House restaurants throughout the southwestern United States. This change, however, has had little impact on our customers. In fact, only about 2 percent of customers have complained, indicating that an average of 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 do not distinguish butter from margarine or they use the term 'butter' to refer to either butter or margarine."

The following appeared in a memo from a vice president of Alta Manufacturing.
"During the past year, Alta Manufacturing had thirty percent more on-the-job accidents than nearby Panoply Industries, where the work shifts are one hour shorter than ours. Experts believe that a significant contributing factor in many accidents is fatigue caused by sleep deprivation among workers. Therefore, to reduce the number of on-the-job accidents at Alta, we recommend shortening each of our three work shifts by one hour. If we do this, our employees will get adequate amounts of sleep."

The vice president of human resources at Climpson Industries sent the following recommendation to the company's president.
"In an effort to improve our employees' productivity, we should implement electronic monitoring of employees' Internet use from their workstations. Employees who use the Internet from their workstations need to be identified and punished if we are to reduce the number of work hours spent on personal or recreational activities, such as shopping or playing games. By installing software to detect employees' Internet use on company computers, we can prevent employees from wasting time, foster a better work ethic at Climpson, and improve our overall profits."

The following appeared in a memorandum written by the chairperson of the West Egg Town Council.
"Two years ago, consultants predicted that West Egg's landfill, which is used for garbage disposal, would be completely filled within five years. During the past two years, however, the town's residents have been recycling twice as much material as they did in previous years. Next month the amount of recycled material—which includes paper, plastic, and metal—should further increase, since charges for pickup of other household garbage will double. Furthermore, over 90 percent of the respondents to a recent survey said that they would do more recycling in the future. Because of our town's strong commitment to recycling, the available space in our landfill should last for considerably longer than predicted."

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."

Milk and dairy products are rich in vitamin D and calcium—substances essential for building and maintaining bones. Many people therefore say that a diet rich in dairy products can help prevent osteoporosis, a disease that is linked to both environmental and genetic factors and that causes the bones to weaken significantly with age. But a long-term study of a large number of people found that those who consistently consumed dairy products throughout the years of the study have a higher rate of bone fractures than any other participants in the study. Since bone fractures are symptomatic of osteoporosis, this study result shows that a diet rich in dairy products may actually increase, rather than decrease, the risk of osteoporosis.

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.

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, we predict that Happy Pancake House will be able to increase profits dramatically if we extend this cost-saving change to all our restaurants in the southeast and northeast as well."

In a study of the reading habits of Waymarsh citizens conducted by the University of Waymarsh, most respondents said they preferred literary classics as reading material. However, a second study conducted by the same researchers found that the type of book most frequently checked out of each of the public libraries in Waymarsh was the mystery novel. Therefore, it can be concluded that the respondents in the first study had misrepresented their reading preferences.

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."

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."
