In a presentation, an exercise involving two participants is referred to as what?

In the context of presentation techniques, an exercise involving two participants is best described as "Energizers." Energizers are interactive activities designed to re-engage participants, stimulate their energy levels, and foster interaction. This type of exercise typically involves small groups, which can include pairs, and serves to break the ice or invigorate the atmosphere during a presentation.

Energizers often entail brief, dynamic activities that encourage movement, laughter, or teamwork, thus reinforcing connections between participants. By incorporating two participants, the activity not only accomplishes the goal of energizing the group but also facilitates personal engagement and communication, essential components of effective learning and retention.

Other options, such as group activities, collaborative exercises, and discussion groups, usually involve larger groups or focus on different interaction dynamics that do not specifically highlight the pairing of two individuals in a rejuvenating format as energizers do.
