The scope of a message will generally be longer when

A) the audience is unfamiliar with your topic.
B) the audience is familiar with you and your credibility.
C) the audience is supportive of your ideas.
D) your subject is noncontroversial.
E) the audience is familiar with the topic.

Answer: A
Explanation: A) The scope of your message is the range of information you present, the overall length, and the level of detail–all of which need to correspond to your main idea. The number of words, pages, or minutes you need to communicate and support your main idea depends on your topic, your audience members' familiarity with the material, their receptivity to your conclusions, and your credibility. You will also need more words or time to build a consensus about a complex or controversial subject, especially if the audience is likely to resist your ideas.
