Final answer:
The final sentence of the speech effectively acknowledges the reality of a stressful situation, which builds rapport with the audience through empathy and pathos, and avoids a forceful tone or authoritative stance.
Step-by-step explanation:
The final sentence in the speech is effective because A. It acknowledges the reality of a stressful situation. This acknowledgment serves as a way to build a connection with the audience by expressing empathy and understanding of their struggle. It also employs pathos as a rhetorical strategy rather than a direct appeal to authority or a forceful call to action, inviting the audience into a constructive conversation. By saying, "I understand how difficult the past few months have been," the speaker is aligning themselves with their audience's experiences, defusing potential defensiveness and setting the stage for mutual support and perseverance through challenging times.
