Answer:
Identifying the intended audience of a speech can be helpful in determining its central idea because the speaker's message and purpose may be tailored to that specific audience. The central idea of a speech is the main point that the speaker wants to convey to the audience, and it is often influenced by the speaker's goals, values, beliefs, and attitudes.
The intended audience of a speech can provide important clues about the speaker's goals and values. For example, a speech delivered to a group of business executives may have a different central idea than a speech delivered to a group of high school students. The speaker may use different language, examples, and arguments depending on the audience.
By identifying the intended audience of a speech, it is possible to gain insights into the speaker's perspective and purpose, which can help to clarify the central idea of the speech. This information can also be used to analyze the rhetorical strategies that the speaker employs to persuade the audience and achieve their goals.
Overall, identifying the intended audience of a speech can provide valuable context and insights into the central idea of the speech. It can help to explain why the speaker is making certain arguments and using particular strategies to persuade their audience.
