Why must informative speakers be careful not to overestimate what the audience knows about the topic? listeners can become lost listeners will become frustrated the audience might interrupt and ask questions listeners will lose interest

Listeners can become lost

Explanation:

Informative speakers need to judge their audience before they speak. They need to know some facts about their listeners, where do they come from, from which background socially and ethnically, and they may want to know something about their religion or interests. This way they can judge the level of the audience's knowledge about the subject they will speak upon.

If the informative speakers overestimate the listeners' knowledge on a particular subjects, the listeners will become frustrated because they won't understand what the speakers are telling them. They may consider themselves to stupid or not knowledgeable enough to listen to this speech. After trying to understand, they give up in the end and can become lost, not understanding the speaker and the topic he speaks upon.
