What rhetorical device is used at the end of the excerpt and why?

The excerpt describes the many new professions and needs that arise in a luxurious city, concluding with the question: "who were not needed and therefore had no place in the former edition of our State, but are needed now?" This is a rhetorical question.

• A rhetorical question is asked for effect or to make a point, rather than to elicit an actual answer. In this case, the question is designed to make the audience reflect on the extensive list of new roles and implicitly agree that a luxurious state indeed requires more resources and people. It guides the audience to the speaker's conclusion.

Let's evaluate the options:

• The first option states "the rhetorical question, because it persuades the audience to agree with the speaker." This accurately describes the function of the question at the end of the excerpt. It highlights the increased needs of a luxurious state, leading the audience to concur with the idea that more resources are necessary.
• The second option mentions "the use of logos, because the facts presented help the audience trust the speaker." While the list of professions could be seen as logical consequences, the primary rhetorical device at the end is the question, and the list itself doesn't primarily build trust in the speaker's credibility (ethos) but rather illustrates the point.
• The third option suggests "the rhetorical question; because it makes the audience question the speaker." This is incorrect; rhetorical questions are typically used to affirm a point, not to invite doubt about the speaker.
• The fourth option refers to "the use of ethos, because the focus on right and wrong convinces the audience that the speaker's opinion is right." The excerpt focuses on the practical needs of a luxurious state, not primarily on moral right or wrong to establish the speaker's credibility.

The rhetorical question at the end of the passage effectively emphasizes the speaker's point about the increased resource demands of a luxurious state, thereby persuading the audience.

The correct option is:

• the rhetorical question, because it persuades the audience to agree with the speaker
