In case of a safety violation, what action could result in demerits?

Chewing gum during practice could lead to demerits because it is often viewed as a safety violation within a drill team context. Participating in drills and routines requires full attention and proper bodily control, and chewing gum might distract a member or lead to accidents, particularly in formations where precision is key. Additionally, there may be team rules prohibiting gum to maintain professionalism or cleanliness during performances.

The other options, while they may also affect team dynamics or commitments, are typically not categorized as safety violations. Not attending practice or missing a practice usually relates more to attendance and commitment rather than safety. Ignoring announcements may reflect on discipline or communication but does not pose a direct safety risk during physical activities. Therefore, chewing gum during practice is specifically linked to safety concerns, making it the relevant choice for receiving demerits.
