Marketing Director: Our new advertising campaign, which focuses on emotional appeal rather than product features, has been highly successful. Since its launch, our sales have increased by 15%, while our competitors' sales have remained flat. This clearly demonstrates that emotional advertising is more effective than feature-based advertising in our market.
- AThe competitors' advertising campaigns during this period were primarily feature-based.
- BThe increase in sales is not attributable to other factors, such as a general market upturn or a decrease in competitor pricing.
- CConsumers in this market are generally more swayed by emotional appeals than by rational considerations of product features.
- DThe 15% sales increase is a statistically significant improvement for the company.
Show answer & explanationAnswer & explanation
Correct answer: B. The increase in sales is not attributable to other factors, such as a general market upturn or a decrease in competitor pricing.
The Marketing Director concludes that the new advertising campaign *caused* the sales increase and outperformed competitors. This is a causal argument. For the campaign to be the sole cause of the sales increase and the observed difference, other potential causes for the sales increase or for the sales difference must be ruled out. Option B directly addresses this by stating that 'the increase in sales is not attributable to other factors,' which is a necessary assumption to attribute the success solely to the new campaign.
Why the other options are wrong
- A. The argument compares 'emotional appeal' to 'feature-based advertising.' For the comparison to be valid, it's assumed that the competitors' advertising represents the 'feature-based' alternative. This is a crucial, though unstated, part of the comparison.
- C. While this might explain *why* emotional advertising is effective, it's not a necessary assumption for the conclusion that *this specific campaign* was successful and more effective than competitors' campaigns. The argument is about the observed results.
- D. The argument implies significance by stating a '15% increase' and 'clearly demonstrates,' but the *statistical* significance isn't a necessary assumption for the logical flow of the argument, though it would be for a rigorous scientific claim.
Necessary Assumption (Causal)
A necessary assumption in a causal argument is an unstated premise that must be true for the stated cause-and-effect relationship to hold, often by ruling out alternative causes or ensuring the cause precedes the effect.
- The argument claims one event (the cause) directly leads to another (the effect).
- A necessary assumption often eliminates alternative causes for the effect.
- It can also ensure there are no other factors preventing the cause from producing the effect.
- To test, negate the assumption: if the argument's conclusion becomes impossible or illogical, it's necessary.
Memory trick: Causal arguments need 'NO GAP': No other cause, Only that cause, Precedes, Absence of interfering factors.
