For mixed elements, how are required pairs treated in accordance with their shape?

The correct choice highlights that required pairs must be part of the specific shape dictated by the element being performed. In synchro skating, mixed elements involve skaters forming pairs that contribute to the overall configuration. The integrity and appearance of the shape are vital for the execution of the element, as the judges assess the performance based on how well these pairs integrate into the overall formation.

In structured elements, pairs are not merely standalone components; they need to cohesively fit into the formation being demonstrated. This contributes to the level of difficulty and presentation value of the element, which impacts the scoring. Recognizing that pairs must adhere to the element's design rather than functioning independently emphasizes the importance of synchronization and the visual cohesiveness of the routine.

Understanding this relationship between required pairs and their necessary inclusion in the shape helps skaters focus on not just the individual performance of pairs but also on how they contribute to the larger formation, which ultimately affects the technical assessment in competitions.
