Final answer:
Patrick Henry uses rhetorical questions (option c) in his closing line to evoke a powerful emotional response, challenging listeners to value liberty over life or peace under oppression.
Step-by-step explanation:
In Patrick Henry's closing line, he employs the technique of a rhetorical question to compel listeners to join the cause of liberty. The use of this device is intended to provoke thought and challenge the audience into taking action, without expecting an actual response.
By questioning the value of life and peace when it costs one's freedom, he stirs the emotional pool of his listeners, urging them to realize that liberty is priceless and worth fighting for. Henry's impassioned plea emphasizes the unacceptable trade-off between liberty and enslavement, effectively rallying support for the American Revolution.
A rhetorical question is a question asked for effect or to make a point, rather than to elicit an answer. Henry asks, 'What is it that gentlemen wish? What would they have? Is life so dear, or peace so sweet, as to be purchased at the price of chains and slavery?'
