Literary critic: A folktale is a traditional story told in an entertaining way, which may lead some to think that folktales lack deeper meaning. But this is not the case. A folktale is passed along by a culture for generations, and each storyteller adds something of his or her own to the story, and in this way folktales provide great insight into the wisdom of the culture. The main conclusion of the literary critic's argument can be properly inferred if which one of the following is assumed? ['A story that is told primarily for entertainment does not necessarily lack deeper meaning.', 'Not every tale that lacks deep meaning or beauty is told solely for entertainment.', 'Any tale that provides insight into the wisdom of a culture is deeply meaningful in some respect.', 'Any tale that is passed along by a culture for generations can provide great insight into the wisdom of that culture.']
