What is the main purpose for visual aids?
They break up the monotony of a piece of writing.
They add validity to the paper.
They help explain the information in another way.
They make the paper look more professional.
The correct answer is the third option, they help explain the information in another way. It has nothing to do with being professional nor does it add to validity. It can help people understand things better or it can keep their attention because just plain presentations without them can often be dry and boring. They do break up the monotony, but it's not the primary reason.
