Which multimedia element would most appeal to an audience’s emotions in a presentation about global warming?

1. a graph showing an increase in airborne chemicals affecting the ozone layer
2. a photo of a dried-up lake and a photo of a family swimming in the lake before it dried up
3. an interview with a scientist explaining the risks that carbon poses to the ozone layer
4. a video lecture of a professor discussing changes in climates around the world

 The correct answer is :  2. a photo of a dried-up lake and a photo of a family swimming in the lake before it dried up.

Explanation:  The audiovisual material in addition to adapting to the subject, supporting the message that is being offered, must create interest in the public. An image, in this case a very well chosen photo can greatly impact and generate awareness and awareness among attendees.

Number 2

The public get bored reallly easily so the other options seem a bit boring for number 4 or number 1

It could as well be number 3 but it says MULTIMEDIA and APPEAL TO AN AUDIENCE so I believe its Number 2

1. read the following excerpt from franklin d. roosevelt's "fireside chat 19":

on the other side of the picture, we must learn also to know that guerilla warfare against the germans in, let us say serbia or norway, us; that a successful russian offensive against the germans us; and that british successes on land or sea in any part of the world strengthen our hands.

remember always that germany and italy, regardless of any formal declaration of war, consider themselves at war with the united states at this moment just as much as they consider themselves at war with britain or russia. and germany puts all the other republics of the americas into the same category of enemies. the people of our sister republics of this hemisphere can be honored by that fact.  

the true goal we seek is far above and beyond the ugly field of battle. when we resort to force, as now we must, we are determined that this force shall be directed toward ultimate good as well as against immediate evil. we americans are not destroyers — we are builders.
