When explaining a visual aid, it is important to resist the temptation to look primarily at the aid rather than at the audience?

This statement is true.
It is important to look at your audience at all times rather than pay more attention to your visual aids. Maintaining eye contact with your audience is relevant because they will be more attentive to what you are saying if you look at them directly. You can point to your visual aids from time to time, but try to focus on your audience.
