Answer: Event Recording
Explanation:Event recording can be defined as a process by which an observer documents the number of times a behavior occurs. A tally/document is used by the observer using event recording for recording each time a student/individual involved in a target behavior. It should also be noted that the duration in which the behavior is being observed is recorded by the observer .
The most obvious reason is that one has to pack up and go because things are not so good at home. Long ago, that probably meant that the climate had changed and made life impossible. It might have become too hot or too cold or too wet, which in turn would have affected not only quality of life but also make survival a shaky proposition. Drought, flood, and temperature changes could certainly push people to move on.
I hope that helped a little.
