 Now, what counts as an answer to the question? Linguists distinguish between different kinds of answers that one might give to a question. An exhaustive answer to “How could S Φ?” would specify all the ways in which S could Φ; a mention-some answer, instead, would specify only one way in which S could Φ. For example, an exhaustive answer to the question “How could S make pasta?” would specify all different recipes for making pasta. A mention-some answer to the same question, instead, would specify (at least) only one recipe. When we ascribe knowledge-how, we don’t expect people to know all the possible ways of performing the relevant task. For example, “Mary knows how to make pasta” can be true, even if Mary only knows one recipe for pasta. This gives us the following truth conditions:
