Answer:
as a persuasive device encouraging students to vote in a school election
Step-by-step explanation:
The image of a young teenager casting his votes can serve as an effective way of convincing fellow students to vote in a school election. This image creates a bandwagon effect on the other students because they will have the impression that since their mates could do it, they too can.
The user of such an image in a multimedia message will be successful in convincing young students to cast their ballots using this image. The impressionable youth will be convinced that voting is the right thing to do especially as other youths are doing it.
