199There is a general idea that waiters and waitresses are more likely to receive larger gratuities from large groups of people. A recent research study suggests this is not true. The researchers examined the relationship between the size of tips in restaurants and the number of meals charged on the bill. They found that, while most tips were around 15 percent, the minimum percentage considered appropriate, people dining alone tipped consistently more (19 percent) and those dining in groups of four or more tipped considerably less (13 percent) than this 15 percent standard. These results strongly suggest that people dining in a group are less likely to feel personally responsible for leaving an adequate or generous tip.

200Statistics collected from dentists indicate that three times more men than women faint while visiting the dentist. This evidence suggests that men are more likely to be distressed about having dental work done than women are. Thus, dentists who advertise to attract patients should target the male consumer and emphasize both the effectiveness of their anesthetic techniques and the sensitivity of their staff to nervous or suffering patients.

201The citizens of Forsythe have adopted healthier lifestyles. Their responses to a recent survey show that in their eating habits they conform more closely to government nutritional recommendations than they did ten years ago. Furthermore, there has been a fourfold increase in sales of food products containing kiran, a substance that a scientific study has shown reduces cholesterol. This trend is also evident in reduced sales of sulia, a food that few of the healthiest citizens regularly eat.

202Humans 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.

203The following appeared in a newspaper feature story.
"At the small, nonprofit hospital in the town of Saluda, the average length of a patient's stay is two days; at the large, for-profit hospital in the nearby city of Megaville, the average patient stay is six days. Also, the cure rate among patients in the Saluda hospital is about twice that of the Megaville hospital. The Saluda hospital has more employees per patient than the hospital in Megaville, and there are few complaints about service at the local hospital. Such data indicate that treatment in smaller, nonprofit hospitals is more economical and of better quality than treatment in larger, for-profit hospitals."

204The following appeared as a letter to the editor of a farming publication.
"With continuing publicity about the need for healthful diets, and with new research about the harmful effects of eating too much sugar, nationwide demand for sugar will no doubt decline. Therefore, farmers in our state should use the land on which they currently grow sugar cane to grow peanuts, a food that is rich in protein and low in sugar. Farmers in the neighboring country of Palin greatly increased their production of peanuts last year, and their total revenues from that crop were quite high."

205The following appeared in a recommendation from the president of Amburg's Chamber of Commerce.
"Last October the city of Belleville installed high intensity lighting in its central business district, and vandalism there declined almost immediately. The city of Amburg has recently begun police patrols on bicycles in its business district but the rate of vandalism there remains constant. Since high intensity lighting is apparently the most effective way to combat crime, we should install such lighting throughout Amburg. By reducing crime in this way, we can revitalize the declining neighborhoods in our city."

206The 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 softball and soccer, over 80,000 of these young players suffered injuries. When interviewed for a recent study, youth-league softball players in several major cities also reported psychological pressure from 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 apparently outweigh any advantages, we in Parkville should discontinue organized athletic competition for children under nine."

207It is known that in recent years, industrial pollution has caused the Earth's ozone layer to thin, allowing an increase in the amount of ultraviolet radiation that reaches the Earth's surface. At the same time, scientists have discovered, the population of a species of salamander that lays its eggs in mountain lakes has declined. Since ultraviolet radiation is known to be damaging to delicate tissues and since salamander eggs have no protective shells, it must be the case that the increase in ultraviolet radiation has damaged many salamander eggs and prevented them from hatching. This process will no doubt cause population declines in other species, just as it has in the salamander species.

208The following appeared in a memorandum from the planning department of an electric power company.
"Several recent surveys indicate that homeowners are increasingly eager to conserve energy and manufacturers are now marketing many home appliances, such as refrigerators and air conditioners, that are almost twice as energy-efficient as those sold a decade ago. Also, new technologies for better home insulation and passive solar heating are readily available to reduce the energy needed for home heating. Therefore, we anticipate that the total demand for electricity in our area will not increase, and may decline slightly. Since our three electric generating plants in operation for the past 20 years have always met our needs, construction of new generating plants should not be necessary."

209The following recommendation was made by the Human Resources Manager to the board of directors of the Fancy Toy Company.
"In the last three quarters of this year, under the leadership of our president, Pat Salvo, our profits have fallen considerably. Thus, we should ask for her resignation in return for a generous severance package. In Pat's place, we should appoint Rosa Winnings. Rosa is currently president of Starlight Jewelry, a company whose profits have increased dramatically over the past several years. Although we will have to pay Rosa twice the salary that Pat has been receiving, it will be well worth it because we can soon expect our profits to increase considerably."

210The following is a letter to the editor of a news magazine.
"Clearly, the successful use of robots on missions to explore outer space in the past 20 years demonstrates that robots could be increasingly used to perform factory work more effectively, efficiently, and profitably than human factory workers. The use of robots in factories would offer several advantages. First, robots never get sick, so absenteeism would be reduced. Second, robots do not make mistakes, so factories would increase their output. Finally, the use of robots would also improve the morale of factory workers, since factory work can be so boring that many workers would be glad to shift to more interesting kinds of tasks."

211The following appeared in a memorandum to faculty from the academic vice president of Waymarsh University.
"So that we can better accomplish Waymarsh University's academic goals, we should adopt the job-opportunity (job-op) program offered at Plateau Technical College and strongly encourage all students at Waymarsh to participate in it. The success of the job-op program at Plateau is evident: over the past two years, more than 75% of the freshmen at Plateau have enrolled in the optional job-op program. Moreover, at Plateau, the grades of job-op students are consistently higher than those of other students, 90% of the job-op students receive job offers within a month after their graduation, and most former job-op students report much success in their careers."

212The following appeared in a memorandum from the new president of the Patriot car manufacturing company.
"In the past, the body styles of Patriot cars have been old-fashioned, and our cars have not sold as well as have our competitors' cars. But now, since many regions in this country report rapid increases in the numbers of newly licensed drivers, we should be able to increase our share of the market by selling cars to this growing population. Thus, we should discontinue our oldest models and concentrate instead on manufacturing sporty cars. We can also improve the success of our marketing campaigns by switching our advertising to the Youth Advertising agency, which has successfully promoted the country's leading soft drink."
------------------------------
213The following appeared in a memorandum from the owner of Armchair Video, a chain of video rental stores
"Because of declining profits, we must reduce operating expenses at Armchair Video's ten video rental stores. Raising prices is not a good option, since we are famous for our special bargains. Instead, we should reduce our operating hours. Last month our store in downtown Marston reduced its hours by closing at 6:00 P.M. rather than 9:00 P.M. and reduced its overall inventory by no longer stocking any film released more than two years ago. Since we have received very few customer complaints about these new policies, we should now adopt them at all other Armchair Video stores as our best strategies for improving profits."

214In each city in the region of Treehaven, the majority of the money spent on government-run public school education comes from taxes that each city government collects. The region's cities differ, however, in the value they place on public education. For example, Parson City typically budgets twice as much money per year as Blue City does for its public schools—even though both cities have about the same number of residents. It seems clear, therefore, that Parson City residents care more about public school education than do Blue City residents.

215The following appeared in a letter to the Grandview City Council from a local business leader.
"During last year's severe drought, when the water supply in the Grandview city reservoir fell to an extremely low level, the city council imposed much more rigid water-rationing rules. But just after these rules were imposed, industrial growth in the area declined. This clearly shows that the new rationing rules have hurt industry in Grandview. Therefore, to promote the health of the local economy, the city council should now stop water rationing."

216The following appeared in a magazine article about planning for retirement.
"Because of its spectacular natural beauty and consistent climate, Clearview should be a top choice for anyone seeking a place to retire. As a bonus, housing costs in Clearview have fallen significantly during the past year, and real estate taxes remain lower than those in neighboring towns. Nevertheless, Clearview's mayor promises many new programs to improve schools, streets, and public services. Retirees in Clearview can also expect excellent health care as they grow older, since the number of physicians in the area is far greater than the national average."
