What should be done if you are unsure of the types of information the audience will need from you?

A) Ask them
B) Follow their blogs
C) Access the knowledge management system
D) Cover all key points in detail
E) Gather more information than needed

When unsure of what information the audience will need from you, it is best to ask them directly. This way, you can tailor your presentation to their specific needs and ensure that they get the information they require. Option B (following their blogs) may not be relevant or practical for all audiences, while option C (accessing the knowledge management system) assumes that such a system exists and is accessible to you. Option D (covering all key points in detail) may result in information overload and lose the audience's attention. Option E (gathering more information than needed) is inefficient and may also result in information overload.
