What does the term evacuation refer to?

The term "evacuation" specifically refers to the mass departure or retreat from an area, often in response to an emergency situation or threat. This practice is essential in scenarios such as natural disasters, hazardous materials incidents, or other emergencies where safety is compromised. During an evacuation, individuals are moved from a dangerous location to a safer environment, ensuring their protection and well-being.

The other choices, like the improvement of living conditions or the establishment of a new settlement, refer to different concepts that are not directly aligned with the definition of evacuation. Emergency response tactics might encompass various strategies, including evacuation, but do not solely define what evacuation means.
