Point at issue:
Professor B: Students should not be able to satisfy foreign language requirements by studying a language that is the native language of many North Americans.
Reasoning: If a language is native to many north americans then it is not a foreign language.
Professor S: Students should be able to satisfy foreign language requirements even if the language in question is the native language of many North Americans.
Reasoning: If people we adhered to Professor B's reasoning then people who study Spanish or French as a foreign language should not be able to so, because they are the native languages of many north americans, yet many people do so.
(A) This point is unique to Professor B's point.
(B) This is not discussed by either. In fact this misrepresents Professor B's point that people should not be able to study as a foreign language languages that are the native many north americans, not necessarily to the individual.
(C) This is not mentioned by either, eliminate.
(D) This is unique to Professor B's point. Professor B says that some universities do this and that they should stop.
(E) Bingo. Professor S thinks no, because if that were the case, Spanish and French would need to be prohibited as well. Professor B thinks yes because he thinks any language that is native to some north americans is not a foreign language.
