 In this case it appears that the asker is requesting an answer that highlights factors that distinguish the alcoholism of the person to whom the question is addressed from that of the others in the group. This and other evidence leads Cross to conclude that how- and why-questions are the same kind of question—both are explanatory questions—and both can be represented as having the structure \(\langle P,X,R,n\rangle\). If a proposition \(A\) must be a reason for \(P\) (in contrast to the rest of \(X)\) in order to bear relation \(R\) to \(\langle P,X,n\rangle\), then the question is worded with ‘why’ and the answer with ‘because’; if \(A\) must be a way for \(P\) to be the case (in contrast to the rest of \(X)\) in order to bear relation \(R\) to \(\langle P,X,n\rangle\), then the question is worded with ‘how’ and the answer with ‘by’, ‘in this way’, or similar wording.
