Final answer:
Repetition in Reagan’s speech reinforces the message that the Berlin Wall's fall is inevitable, highlighting its impotence against faith, truth, and freedom.
Step-by-step explanation:
Repetition in Ronald Reagan’s "Tear Down This Wall" speech is used to emphasize the imperative and inevitability of the wall's collapse. In the excerpt provided, the phrase “this wall will fall” is repeated, enhancing the meaning and drawing the listener’s attention to the central point of Reagan’s message: the inherent weakness of the Berlin Wall before the forces of faith, truth, and freedom. Furthermore, by repeating the assertion that the wall cannot withstand these forces, Reagan drives home the prediction and anticipation of change, making his statement not just a rhetorical declaration but a prophetic one as well.
