For question you are given five paragraphs describing different methods or approaches to the teaching of English as a Foreign Language, adapted from a glossary by Brian Tomlinson. For each of them, choose the alternative which more accurately names it.

An approach to language teaching which stresses the purposes for which expressions are used. Thus, instead of teaching the structures of English (e.g. the tenses, types of clauses, the passive, etc.) a course based on this kind of approach would teach how to express agreement, how to decline an invitation, how to give directions, how to ask for information, etc.
