<p>Argument Construction Situation:- People who are allergic to certain sulfites can avoid risking an allergic reaction by drinking wine from one of the several producers that does not add sulfites. Reasoning:- On what assumption does the argument depend? Drinking wine to which no sulfites have been added will not prevent exposure to sulfites if, for instance, sulfites occur naturally in wines. In particular, if the wines that do not have sulfites added have sulfites present naturally in quantities sufficient to produce an allergic reaction, drinking these wines will not prevent an allergic reaction. The argument therefore depends on assuming that this is not the case. A The argument does not require this because the conclusion does not address allergic reactions to substances other than sulfites. B The argument specifically refers to &acirc;&euro;&oelig;certain sulfites&acirc;&euro; producing allergic reactions. It is entirely compatible with certain other forms of sulfites not producing allergic reactions in anyone. C This is irrelevant. The argument does not claim that one can avoid having an allergic reaction to sulfites from any source just by restricting one&acirc;&euro;&trade;s wine consumption to those varieties to which no sulfites have been added. D Once again, the argument&acirc;&euro;&trade;s conclusion does not address allergic reactions to substances other than sulfites in wine. E Correct. The argument relies on this assumption. The correct answer is E.</p>
