What is the main purpose of visual aids? they make the paper look more professional. they add validity to the paper. they break up the monotony of a piece of writing. they explain the information in another way.

The correct answer is "They help explain the information in another way". Research results can often be monotonous and difficult to understand. This is why if using visual aids you invite your audience to participate in your presentation by being actively involved in both listening and analyzing what is going on on your pictures or presentations or graphs or similar. It is much simpler to explain this way than just by reading.
