Answer
Brief Explanations:
Visual elements in a print Public - Service Announcement (PSA) are meant to support and enhance the message being conveyed. They don't necessarily need to have detailed information (which can be in the text), don't have to be bright and highly colorful (depends on the message), and should not obscure unpleasant facts as PSAs aim for truth - telling.
Answer:
strengthen the message.
