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"Butter has now been replaced by margarine in Happy Pancake House restaurants throughout the southwestern United States.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 filed a formal complaint, 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 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, the Happy Pancake House should extend this cost-saving change to its restaurants throughout the rest of the country."

Write a response in which you examine the stated and/or unstated assumptions of the argument. Be sure to explain how the argument depends on these assumptions and what the implications are for the argument if the assumptions prove unwarranted.

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."

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 data from a survey of high school math and science teachers show that in the district of Sanlee many of these teachers reported assigning daily homework, whereas in the district of Marlee, most science and math teachers reported assigning homework no more than two or three days per week. Despite receiving less frequent homework assignments, Marlee students earn better grades overall and are less likely to be required to repeat a year of school than are students in Sanlee. These results call into question the usefulness of frequent homework assignments. Most likely the Marlee students have more time to concentrate on individual assignments than do the Sanlee students who have homework every day. Therefore teachers in our high schools should assign homework no more than twice a week.

While the Department of Education in the state of Attra recommends that high school students be assigned homework every day, the data from a recent statewide survey of high school math and science teachers give us reason to question the usefulness of daily homework. In the district of Sanlee, 86 percent of the teachers reported assigning homework three to five times a week, whereas in the district of Marlee, less than 25 percent of the teachers reported assigning homework three to five times a week. Yet the students in Marlee earn better grades overall and are less likely to be required to repeat a year of school than are the students in Sanlee. Therefore, all teachers in our high schools should assign homework no more than twice a week.

The following appeared as an editorial in the student newspaper of Groveton College.

"To combat the recently reported dramatic rise in cheating among college students, colleges and universities should adopt honor codes similar to Groveton's, which calls for students to agree not to cheat in their academic endeavors and to notify a faculty member if they suspect that others have cheated. Groveton's honor code replaced an old-fashioned system in which teachers closely monitored students. Under that system, teachers reported an average of thirty cases of cheating per year. The honor code has proven far more successful: in the first year it was in place, students reported twenty-one cases of cheating; five years later, this figure had dropped to fourteen. Moreover, in a recent survey conducted by the Groveton honor council, a majority of students said that they would be less likely to cheat with an honor code in place than without."

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

"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. Therefore, we recommend that the city of Grandview eliminate its funding for the Grandview Symphony from next year's budget. By doing so, we can prevent a city budget deficit without threatening the success of the symphony."

The following appeared in a memo to the board of the Grandview Symphony.

"The city of Grandview has provided annual funding for the Grandview Symphony since the symphony's inception ten years ago. Last year the symphony hired an internationally known conductor, who has been able to attract high-profile guest musicians to perform with the symphony. Since then, private contributions to the symphony have doubled and attendance at the symphony's concerts-in-the-park series has reached new highs. Now that the Grandview Symphony is an established success, it can raise ticket prices. Increased revenue from larger audiences and higher ticket prices will enable the symphony to succeed without funding from the city government."

Hospital statistics regarding people who go to the emergency room after roller-skating accidents indicate the need for more protective equipment. Within that group of people, 75 percent of those who had accidents in streets or parking lots had not been wearing any protective clothing (helmets, knee pads, etc.) or any light-reflecting material (clip-on lights, glow-in-the-dark wrist pads, etc.). Clearly, the statistics indicate that by investing in high-quality protective gear and reflective equipment, roller skaters will greatly reduce their risk of being severely injured in an accident.

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

"When the Grandview Symphony was established ten years ago, the city of Grandview agreed to provide the symphony with annual funding until the symphony became self-sustaining. Two years ago, the symphony hired an internationally known conductor, who has been able to attract high-profile guest musicians to perform with the symphony. Since then, private contributions to the symphony have tripled and attendance at the symphony's outdoor summer concert series has reached record highs. Now that the symphony has succeeded in finding an audience, the city can eliminate its funding of the symphony."

The citizens of Forsythe have adopted more healthful 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.

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."

The following recommendation was made by the president and administrative staff of Grove College, a private institution, to the college's governing committee.

"We recommend that Grove College preserve its century-old tradition of all-female education rather than admit men into its programs. It is true that a majority of faculty members voted in favor of coeducation, arguing that it would encourage more students to apply to Grove. But 80 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. Keeping the college all female will improve morale among students and convince alumnae to keep supporting the college financially."

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 these developments will certainly result in an increased demand for heating oil, we recommend investment in Consolidated Industries, one of whose major business operations is the retail sale of home heating oil."

Benton City residents have adopted healthier lifestyles. A recent survey of city residents shows that the eating habits of city residents conform more closely to government nutritional recommendations than they did ten years ago. During those ten years, local sales of food products containing kiran, a substance that a scientific study has shown reduces cholesterol, have increased fourfold, while sales of sulia, a food rarely eaten by the healthiest residents, have declined dramatically. Because of these positive changes in the eating habits of Benton City residents, we predict that the obesity rate in the city will soon be well below the national average.
