Woven baskets characterized by a particular distinctive pattern have previously been found only in the immediate vicinity of the prehistoric village of Palea and therefore were believed to have been made only by the Palean people. Recently, however, archaeologists discovered such a "Palean" basket in Lithos, an ancient village across the Brim River from Palea. The Brim River is very deep and broad, and so the ancient Paleans could have crossed it only by boat, and no Palean boats have been found. Thus it follows that the so-called Palean baskets were not uniquely Palean.

Humans arrived in the Kaliko Islands about 7,000 years ago, and within 3,000 years most of the large mammal species that had lived in the forests of the Kaliko Islands had become extinct. Yet humans cannot have been a factor in the species' extinctions, because there is no evidence that the humans had any significant contact with the mammals. Further, archaeologists have discovered numerous sites where the bones of fish had been discarded, but they found no such areas containing the bones of large mammals, so the humans cannot have hunted the mammals. Therefore, some climate change or other environmental factor must have caused the species' extinctions.

The following recommendation was made by the president and administrative staff of Grove College, a private institution, to the college's governing committee.
"Recently, there have been discussions about ending Grove College's century-old tradition of all-female education by admitting male students into our programs. At a recent faculty meeting, a majority of faculty members voted in favor of coeducation, arguing that it would encourage more students to apply to Grove. However, Grove students, both past and present, are against the idea of coeducation. Eighty percent of the students responding to a survey conducted by the student government wanted the school to remain all female, and over half of the alumnae who answered a separate survey also opposed coeducation. Therefore, we recommend maintaining Grove College's tradition of all-female education. We predict that keeping the college all-female will improve morale among students and convince alumnae to keep supporting the college financially."

The following appeared in a memo from a vice president of a large, highly diversified company.
"Ten years ago our company had two new office buildings constructed as regional headquarters for two regions. The buildings were erected by different construction companies—Alpha and Zeta. Although the two buildings had identical floor plans, the building constructed by Zeta cost 30 percent more to build. However, that building's expenses for maintenance last year were only half those of Alpha's. In addition, the energy consumption of the Zeta building has been lower than that of the Alpha building every year since its construction. Given these data, plus the fact that Zeta has a stable workforce with little employee turnover, we recommend using Zeta rather than Alpha for our new building project, even though Alpha's bid promises lower construction costs."

The following appeared in a memo from the vice president of marketing at Dura-Sock, Inc.
"A recent study of our customers suggests that our company is wasting the money it spends on its patented Endure manufacturing process, which ensures that our socks are strong enough to last for two years. We have always advertised our use of the Endure process, but the new study shows that despite our socks' durability, our average customer actually purchases new Dura-Socks every three months. Furthermore, our customers surveyed in our largest market, northeastern United States cities, say that they most value Dura-Socks' stylish appearance and availability in many colors. These findings suggest that we can increase our profits by discontinuing use of the Endure manufacturing process."

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 was written as a part of an application for a small-business loan by a group of developers in the city of Monroe.
"Jazz music is extremely popular in the city of Monroe: over 100,000 people attended Monroe's annual jazz festival last summer, and the highest-rated radio program in Monroe is 'Jazz Nightly,' which airs every weeknight. Also, a number of well-known jazz musicians own homes in Monroe. Nevertheless, the nearest jazz club is over an hour away. Given the popularity of jazz in Monroe and a recent nationwide study indicating that the typical jazz fan spends close to $1,000 per year on jazz entertainment, we predict that our new jazz music club in Monroe will be a tremendously profitable enterprise."

The following appeared as part of an article in a business magazine.
"A recent study rating 300 male and female Mentian advertising executives according to the average number of hours they sleep per night showed an association between the amount of sleep the executives need and the success of their firms. Of the advertising firms studied, those whose executives reported needing no more than 6 hours of sleep per night had higher profit margins and faster growth. These results suggest that if a business wants to prosper, it should hire only people who need less than 6 hours of sleep per night."

The following appeared in a memo from the director of a large group of hospitals.
"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."

When Stanley Park first opened, it was the largest, most heavily used public park in town. It is still the largest park, but it is no longer heavily used. Video cameras mounted in the park's parking lots last month revealed the park's drop in popularity: the recordings showed an average of only 50 cars per day. In contrast, tiny Carlton Park in the heart of the business district is visited by more than 150 people on a typical weekday. An obvious difference is that Carlton Park, unlike Stanley Park, provides ample seating. Thus, if Stanley Park is ever to be as popular with our citizens as Carlton Park, the town will obviously need to provide more benches, thereby converting some of the unused open areas into spaces suitable for socializing.

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 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."

Humans arrived in the Kaliko Islands about 7,000 years ago, and within 3,000 years most of the large mammal species that had lived in the forests of the Kaliko Islands were extinct. Previous archaeological findings have suggested that early humans generally relied on both fishing and hunting for food; since archaeologists have discovered numerous sites in the Kaliko Islands where the bones of fish were discarded, it is likely that the humans also hunted the mammals. Furthermore, researchers have uncovered simple tools, such as stone knives, that could be used for hunting. The only clear explanation is that humans caused the extinction of the various mammal species through excessive hunting.

The following appeared in a memo from the vice president 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. If we shorten each of our work shifts by one hour, we can improve Butler Manufacturing's safety record by ensuring that our employees are adequately rested."

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 as a letter to the editor from the owner of a skate shop in Central Plaza.
"Two years ago the city council voted to prohibit skateboarding in Central Plaza. They claimed that skateboard users were responsible for litter and vandalism that were keeping other visitors from coming to the plaza. In the past two years, however, there has been only a small increase in the number of visitors to Central Plaza, and litter and vandalism are still problematic. Skateboarding is permitted in Monroe Park, however, and there is no problem with litter or vandalism there. In order to restore Central Plaza to its former glory, then, we recommend that the city lift its prohibition on skateboarding in the plaza."

There is now evidence that the relaxed pace of life in small towns promotes better health and greater longevity than does the hectic pace of life in big cities. Businesses in the small town of Leeville report fewer days of sick leave taken by individual workers than do businesses in the nearby large city of Masonton. Furthermore, Leeville has only one physician for its one thousand residents, but in Masonton the proportion of physicians to residents is five times as high. Finally, the average age of Leeville residents is significantly higher than that of Masonton residents. These findings suggest that the relaxed pace of life in Leeville allows residents to live longer, healthier lives.

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 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."

In surveys Mason City residents rank water sports (swimming, boating, and fishing) among their favorite recreational activities. The Mason River flowing through the city is rarely used for these pursuits, however, and the city park department devotes little of its budget to maintaining riverside recreational facilities. For years there have been complaints from residents about the quality of the river's water and the river's smell. In response, the state has recently announced plans to clean up Mason River. Use of the river for water sports is, therefore, sure to increase. The city government should for that reason devote more money in this year's budget to riverside recreational facilities.

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 difficulties in obtaining reliable supplies of high quality wool fabric, we discontinued production of our alpaca overcoat. Now that we have a new fabric supplier, we should resume production. This coat should sell very well: since we have not offered an alpaca overcoat for five years and since our major competitor no longer makes an alpaca overcoat, there will be pent-up customer demand. Also, since the price of most types of clothing has increased in each of the past five years, customers should be willing to pay significantly higher prices for alpaca overcoats than they did five years ago, and our company profits will increase."

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."
