If you wanted to help viewers visualize a story or situation which medium would you use? drawings or photos on a page or screen
words on a page or screen
text read aloud
sound effects or music

Honestly I would use all of them, but considering this is probably a text question and you can probably only choose one I's say Drawings or photo's on a page or screen. You need to look back at the question. It says to help people visualize. You wouldn't exactly be giving someone the best visualization experience if you read them text or made them read text. Also if it's just music, what's the person gonna visualize? I'd say yeah all those things can help TO visualize. But not really the best way to go about it.

artists followed a set of rules to achieve ideal proportion.
