For which two reasons would an administrator evaluate a group using group properties in ArcGIS Online? Choose TWO:

Evaluating a group using group properties in ArcGIS Online is essential for a number of administrative tasks. One significant reason is to change ownership of the group. This function is crucial for ensuring that the right individuals maintain control over the group's content and membership. If the current owner leaves the organization or no longer requires control over the group, transferring ownership helps maintain continuity and allows for better management of the group's resources.

While marking items as favorites, reviewing content, and requesting data can be part of working with a group, they are not primary reasons for evaluating group properties. These actions are generally user-centered and pertain more to the everyday interaction with the group's content rather than overarching administrative control and management, which is the primary focus of evaluating group properties in ArcGIS Online.
