Essayist: Lessing contended that an art form' s medium dictates the kind of representation the art form must employ in order to be legitimate; painting, for example, must represent simultaneous arrays of colored shapes, while literature, consisting of words read in succession, must represent events or actions occurring in sequence. The claim about literature must be rejected, however, if one regards as legitimate the imagists' poems, which consist solely of amalgams of disparate images. Which one of the following, if assumed, enables the essayist's conclusion to be properly drawn? ['All art represents something either as simultaneous or as successive.', 'Poems whose subject matter is not appropriate to their medium are illegitimate.', 'An amalgam of disparate images cannot represent a sequence of events or actions.', "All art, even the imagists' poetry, depicts or represents some subject matter."]
