I am doing a rhetorical device project for ap lang and i’m having trouble trying to answer this question: how does this example from barack obama’s 2004 dnc speech shown to be an effective use of climax (the rhetorical device, not the plot of a story)?

if you need a definition of climax, it is a rhetorical device in which words, phrases, or clauses are arranged in order of increasing importance.
