Argument Flow:
The ad starts with a statistic about hospital usage, then jumps to a conclusion about effectiveness and consumer choice. It moves from 'what hospitals do' to 'what you should do' based on the assumption that hospital usage equals effectiveness.
Main Conclusion:
Novex is the most effective painkiller for sinus pain and the one you should choose.
Logical Structure:
The argument assumes that if most hospitals use Novex, then Novex must be the most effective option for consumers. This creates a weak link because hospital usage patterns don't necessarily prove effectiveness - hospitals might choose Novex for reasons like cost, availability, contracts, or convenience rather than superior effectiveness.
Prethinking:
Question type:
Weaken - We need to find information that reduces belief in the conclusion that Novex is the most effective painkiller for sinus pain
Precision of Claims
The argument makes a quality claim about effectiveness based on a quantity claim about hospital usage (3 out of 4 hospitals use Novex)
Strategy
Look for scenarios that break the connection between 'hospitals choose Novex' and 'Novex is most effective.' We need to show that hospitals might choose Novex for reasons other than effectiveness, or that hospital choices don't necessarily indicate effectiveness
This choice talks about competing brands being intended for other types of pain in addition to sinus pain. However, this doesn't weaken the argument about Novex being most effective for sinus pain specifically. If anything, it might suggest that Novex is more specialized for sinus pain, which could support rather than undermine the ad's claim.
This discusses hospitals using Novex as a backup option for patients who can't tolerate their usual drug. This actually suggests that Novex isn't the first choice for most hospitals, which might weaken the argument. However, it doesn't directly challenge the effectiveness claim since hospitals might still consider Novex effective - just not their primary option for other reasons.
This directly attacks the core assumption of the argument by providing an alternative explanation for hospital usage patterns. If hospitals choose Novex primarily because manufacturers offer it at the lowest possible price, then the statistic about hospital usage doesn't necessarily indicate superior effectiveness. This breaks the critical connection between 'hospitals use it' and 'it's most effective,' seriously undermining the advertisement's reasoning.
The fact that Novex is available without prescription doesn't weaken the effectiveness claim. This is about accessibility and convenience, not about whether the drug is actually more effective than competitors for treating sinus pain.
This choice actually strengthens the argument rather than weakening it. If clinical trials show Novex is more effective than competing brands, this supports the advertisement's claim about effectiveness, even though the ad's reasoning process was flawed.
