Build line of reasoning in TOK exhibition commentary

A student is planning exhibition commentary for a recorded oral-history transcript and the prompt "What role does memory play in knowledge?". Choose the line of reasoning that keeps the commentary coherent. Select the exhibition thread, the object sequence, the commentary move, and the exhibition boundary. Then answer this in your own words: why would this route keep the TOK reasoning focused? AI will analyse your reasoning, example or object use, and expression.
