What is a fundamental requirement for the General Element in pairs?

The fundamental requirement for the General Element in pairs is that all pairs must perform the same supported position. This means that while there may be variability in the choreography or execution within the routines, the element itself must have a consistent basis across all participating pairs. This establishes a standardized parameter for evaluation, ensuring that the technical skill displayed is comparable among different pairs.

This requirement highlights the importance of synchronization and uniformity within certain elements of the performance. By performing the same supported position, skaters can demonstrate their ability to execute complex moves while maintaining the coordination and harmony characteristic of pairs skating. Moreover, it allows judges to assess the quality and difficulty of the execution under the same criteria, facilitating a fair comparison between performances.

The other options do not align with the fundamental requirement. For example, pairs choosing different features would disrupt uniformity, while each skater having a unique movement could compromise the essential aspect of synchronization needed in pair performances. Similarly, allowing different numbers would contradict the need for a cohesive element that can be evaluated uniformly across all pairs.
