The excerpt from paragraph 5 that contains an example of the author using pathos to convey his point of view would be: "John Muir, who led the opposition, wrote beautifully about the valley, calling it 'one of Nature's rarest and most precious mountain temples.' He appealed to the nation, asking what else might be at stake if we allowed the creation of a 'water tank' in this national park."
What is pathos?
Pathos refers to a rhetorical technique in which the creator of the writing appeals to and evokes the audience's emotions in a way that persuades or creates a strong sense of connection. It is often used in literature and writing to sway the audience a particular way.
In the above excerpt, the author evoked emotions by proposing a question that branches off to numerous consequences of creating a water tank in the national park. A sense of connection is created in this when the reader realizes the creation of water tanks can be detrimental; the author appealed to emotions by striking thought upon possible harms.
