A GIS technician has a feature class that contains thousands of features. The technician needs to control when certain features within the feature class draw on the map as they zoom in or out.

Which method should be used to accomplish this?

A cartographer is authoring a layout that currently includes one map and would like to provide additional context by adding another map to the layout.
