Answer:
1. Central ideas
2. Language
3. Audience
Explanation:
When structuring a speech, the speaker should take into account different variables that will enable him/her to create an impact on the audience.
First and foremost, the speaker should define which are the central ideas of the text that will be converted into a speech. Central ideas are important because a speech should be direct, coherent, and consistent.
Moreover, the speaker should take into account the type of audience that will be hearing the speech, which is correlated to the type of language to use. For instance, if the speech is directed to high school students, then, the speaker should avoid the overuse of technicisms and use a friendlier language to keep them interested in the ideas of the speech.
