These two models have almost identical specifications and features, and they sell for almost the same price. Both were introduced on the market five years ago, and each year, the respective manufacturers spend about the same amount in advertising. In the past five year, the total number of TJ-700's sold is about 80% greater than the total number of Beta Turbomax's sold. Clearly, the advertising firm that created TJ-700 ads created much more effective ads than the firm that created Beta Turbomax ads.
In evaluating the argument, it would be most useful to know which of the following?
A. How the advertising budgets over the last five years for the TJ-700 and the Beta Turbomax compare to the budgets over the same period for comparable models of other manufacturers.
B. Whether the ads for the TJ-700 and the Beta Turbomax included the address or websites of local dealerships selling these models.
C. Whether buyers of the TJ-700 and the Beta Turbomax reported being familiar with the ads of these cars.
D. What percentage the first two years maintenance costs of each model is of their respective advertising budgets.
E. Whether buyer of cars of other manufacturers in the last five years are familiar with the ads for the TJ-700 and the Beta Turbomax.
