Answer:
jokes to entertain audience? but definitely not lots of information on each slide
Step-by-step explanation:
it makes it more "draining" and long for the audience to see a bunch of information, but depending on how formal it is, you could consider having a decent amount. presentation is definitely key, so if the fonts are, not necessarily complicated, but match (on a more graphically-measured level) nicely with backgrounds, pictures, etc. then it will be more appealing and hooking, wether consciously or subconsciously, for the audience.
