Analysis of Argument Questions for the GMAT
The following appeared as part of an annual report sent to stockholders by Olympic Foods, a processor of frozen foods.
?Over time, the costs of processing go down because as organizations learn how to do things better, they become more efficient. In color film processing, for example, the cost of a 3-by-5-inch print fell from 50 cents for five-day service in 1970 to 20 cents for one-day service in 1984. The same principle applies to the processing of food. And since Olympic Foods will soon celebrate its twenty-fifth birthday, we can expect that our long experience will enable us to minimize costs and thus maximize profits.

ATE-- The author assumes that film processing is like food processing.  Notice that food processing is really old and film is new, so innovations have already happened in food making it not like film.
GA--"once a company has 25 years of experience it will come up with new innovations"  in reality these things happen slowly and the if the author wants to convince us that innovations are coming up he should talk about the R&D the company is doing now.
The following appeared in a memorandum from the business department of the Apogee Company.
?When the Apogee Company had all its operations in one location, it was more profitable than it is today. Therefore, the Apogee Company should close down its field offices and conduct all its operations from a single location. Such centralization would improve profitability by cutting costs and helping the company maintain better supervision of all employees.?
Discuss how well reasoned . . . etc.
OS--May have been more profitable in the past because of different reasons (better leadership, better economy, etc)
GA--"Moving to a single office will allow  for better supervision of employees"  perhaps the employees are well supervised in the field offices.
GA--"company can do all of its business from one location"  perhaps closing field offices would make it impossible to get to the same number of customers
The following appeared in a memorandum issued by a large city?s council on the arts.
?In a recent citywide poll, fifteen percent more residents said that they watch television programs about the visual arts than was the case in a poll conducted five years ago. During these past five years, the number of people visiting our city?s art museums has increased by a similar percentage. Since the corporate funding that supports public television, where most of the visual arts programs appear, is now being threatened with severe cuts, we can expect that attendance at our city?s art museums will also start to decrease. Thus some of the city?s funds for supporting the arts
