When analyzing your audience using direct observation during your speech, what is something that you cannot observe about your audience?

The level of their knowledge and education.

Explanation:

While delivering a speech, there are many factors in which speaker needs to observe and molding himself in the same manner as having the attention of the audience. It's a two-way process where communication is based on the speaker's way of speaking and audience way of response.

Speakers can only understand the level of consuming the meaning of the speech by the audience by their facial experience, gesture, and response but speakers can't understand their education level while observing them.
