Are what scenarios does not describe an example of continuity over time?

ScenariOS that do not describe continuity over time include dramatic shifts in cultural practices, such as a society abruptly abandoning a long-standing tradition in favor of a completely new one without any transitional phase. Another example is the sudden collapse of a political system, resulting in a complete overhaul of governance without any remnants of the previous structures. Additionally, instances where technological advancements render previous methods obsolete overnight, like the rapid shift from landlines to smartphones, illustrate a break in continuity.
