Question

which best describes the purpose of the rhetorical questions kennedy asks in \among free men\?
they appeal to timeliness, reminding the audience of martin luther king jr.s death the previous day.
they support an appeal to logic by suggesting how illogical the use of violence is.
they are an appeal to audience members sense of right and wrong.
they appeal to the audience members emotions by revealing kennedys anger

Explanation:

Rhetorical questions are used to engage the audience and make them reflect on moral and ethical aspects. In this context, appealing to the sense of right and wrong (a moral/ethical appeal) is a common use of rhetorical questions in speeches. The other options either focus on a single event (Martin Luther King Jr.'s death - which is more about timeliness but not the main purpose of rhetorical questions here), an appeal to logic (but the nature of rhetorical questions in such a speech context is more about moral judgment than just logical illogicality of violence), or an emotional appeal through the speaker's anger (which is too narrow as the focus is more on the audience's internal moral compass).

Answer:

They are an appeal to audience members' sense of right and wrong.
