Argument Evaluation

Situation s. An advertisement claims that Novex is the most effective painkiller for sinus pain since three out of four hospitals use it for patients.

Reasoning What paint undermines the advertisement's claim? The argument for Novex's effectiveness as a painkiller is based upon the hospitals^' usage. Consider what might be driving the hospitals' choice of medications to administer. Three out of four hospitals might be giving their patients Novex not because it is the most effective painkiller for sinus pain, but because it is inexpensive. If this is the case, the argument is seriously undermined.

A         Other kinds of pain are irrelevant to the argument since the claim is only about sinus pain.

B          This point does not undermine the advertisement's claim.

C          Correct. This statement properly identifies a factor that could well undermine the advertisement's claim: the hospitals may be using this medication because it is the most cost effective for them.

D         Novex's nonprescription formula is not relevant to the claim.

E         

s

This point strengthens, rather than weakens, the claim. The correct answer is C.
