Final answer:
Numerical information is best displayed in graph form, an influential speech should be shared as audio, and predator animals can be best exemplified using images.
Step-by-step explanation:
Matching each type of information to the multimedia element that would best emphasize it helps enhance understanding and engagement. For numerical information about reading habits in different US regions, a graph is most appropriate as it visually organizes numerical data, allowing for easy comparison and visualization of trends. When the content is a speech by an influential person, audio is the best choice to convey the speaker's tone, emotion, and emphasis. An example of a type of predator animal is depicted most effectively through an image, as it provides a visual reference that can detail features and context better than text or audio alone.
