If Fencer X commits a second offense resulting in a Group 1 violation after already receiving a Group 1 YELLOW CARD, what should the Referee do?

When Fencer X commits a second offense that is categorized as a Group 1 violation, after already having received a Group 1 yellow card, the appropriate response is to issue a red card. A red card signifies a more severe reprimand and reflects the escalation of infractions.

In the context of fencing rules, initially receiving a yellow card serves as a warning. However, if the same fencer commits subsequent offenses leading to another Group 1 infraction, the rules dictate that a stronger penalty, such as a red card, must be applied. This red card results in the fencer being disqualified from the match, ensuring compliance with the expected standards of conduct during competition.

The other choices would not be appropriate in this situation. Issuing another yellow card or giving a verbal warning does not reflect the severity of a second infraction after the initial warning has already been given. Dismissing the fencer from the match would typically occur in more extreme situations beyond the prescribed protocol for escalating punishments, thus making the red card the correct course of action in this scenario.
