These are the only ones that make sense. Displaying all of the notes on the screen is uneffective, as most people will not read everything. Only having the multimedia in one section of the presentation can lead to people not paying attention. I am 100% sure this is correct.
The most important strategy is to be clear and concise, because if you include lots of text in the presentation, it's impossible for the audience to read it and enjoy the presentation.
The second most important feature is the providing of relevant examples. As it's written in the previous item, being clear and concise implies using enough ammount of text and alsogives the presenter the freedom to speak to the audience and keep eyesight, as you don't have to read from the presentation.
Last but not least, the use of appropriate visual elements is important due to the way it calls the attention of the audience. Besides the information you are presenting, the most important part of the presentation is the audience, so it's important to have them engrossed in what you're showing to them.
