580 - Logical Reasoning

During the past year, Boz Corporation, a cigarette manufacturer, has engaged in a "corporate image" advertising campaign. One executive now urges that the advertising be extended for another year because profits have increased by 29% over the previous year. Another executive, however, is skeptical. She observes that the increases are typical for the industry over the past year, although none of their competitors have used corporate image advertising.
The most accurate way of summarizing the second executive's point would be:

1. She argues that the effect may not really be due to its supposed cause because there has not been a sufficient lapse of time between the cause and the effect.
2. She argues that the assignment of a cause for this effect is premature, because there is as yet no well-established theory of such interactions.
3. She argues that corporate image advertising is unprofitable, since it has evidently benefited competitors as much as the corporation that paid for it.
4. She knows that effective advertising requires a constant influx of new ideas and approaches, and she argues that one year of corporate image advertising is enough for awhile.
5. She argues that the effect may not be due to its alleged cause since the same effect is found elsewhere without that cause.
