Read the excerpt from "save the redwoods."
in the course of my explorations twenty-five years ago,
i found five sawmills located on or near the lower margin of
the sequoia belt, all of which were cutting more or less big
tree lumber, which looks like the redwood of the coast, and
was sold as redwood. one of the smallest of these mills in
the season of 1874 sawed two million feet of sequoia
lumber. since that time other mills have been built among
the sequoias, notably the large ones on kings river and
the head of the fresno.

Explanation:

The given excerpt is written by John Muir. John Muir had been an influential activist and had worked to preserve many wilderness areas for instance, Sequoia National Park.

In the given excerpt, the type of appeal that Muir made is 'Ethos' or 'an appeal to ethics or author's credibility'.

Ethos or 'an appeal to author's credibility' is one of the mode of persuasion.

The one who presented this idea of 'mode of persuasion' is Aristotle. According to him, a speaker influences his audience or appeals to his audience in three ways, namely, 'ethos', 'pathos', and 'logos'.

Ethos or an appeal to 'ethics' or 'author's credibility' is the method of persuasion in which speaker's audience gets to know about the speaker's or author's credibility or how much the speaker knows about the topic he is speaking about.

In the given excerpt Muir's audience can clearly identify that he has knowledge about what he acknowledging in his speech or can identify the credibility of the author. So, the correct option is A.

both the address and the poster use diction to convey their message. diction is defined as a style of writing or speaking based on the types of words chosen in order to send a message. parallelism is when a similar sentence structure is used for several sentences on a text; roosevelt's address doesn't follow that. repetition has to do with repeating a word or sentence in order to emphasize and idea, however neither the poster nor the address use repetion. finally, the address doesn't use images to convey a message.
