The special event among the options provided that is NOT a special event is the "Boy Scouts meeting." Here's why:
1. Boy Scouts meetings are regular, recurring gatherings of the Boy Scouts organization for their activities and discussions. They are not considered one-time special events like graduations, weddings, or the Olympics.
2. Graduation, weddings, and the Olympics are examples of special events that typically occur on specific dates, marking significant milestones or occasions. Graduations celebrate academic achievements, weddings celebrate the union of two individuals, and the Olympics are a major international sporting event that takes place every few years.
In summary, while graduations, weddings, and the Olympics are special events that happen on specific occasions, Boy Scouts meetings are not considered special events as they are regular meetings for the organization's members.
