Which type of crisis is characterized by unexpected and non-normative life events?

The correct choice is non-normative crisis. This type of crisis is defined by unexpected life events that do not follow the usual patterns or developmental stages that individuals typically experience. Non-normative crises can include events such as a sudden job loss, an unexpected death in the family, or an unforeseen medical emergency. These events tend to arise spontaneously and are not part of the typical life course, causing significant stress and requiring individuals or families to adapt to new circumstances.

In contrast, a normative crisis refers to challenges that are predictable and expected based on societal norms or developmental stages, such as transitioning from adolescence to adulthood. Selected crisis and standard crisis are not recognized as established categories within this context, which makes them less accurate descriptions of crisis types related to life events.
