Agent Jennings makes a presentation on Medicare advertised as an educational event. Agent Jennings distributes materials that are solely educational in nature. However, she gives a brief presentation that mentions plan-specific premiums. Is this a prohibited activity at an event that has been advertised as educational?

Yes it is

Explanation:

Yes. When an event has been advertised as educational, going ahead to discuss plan-specific premiums is impermissible

The event for which Mary made the presentation is clearly an educational event so she should have concentrated fully on only educational contents that pertains to the event. Giving a presentation that mentions plan-specific premiums no matter how brief is a deviation from the main focus of the event. Therefore it is impermissible for her to do so.
