Pick the two:
- Events that ended major divisions of geologic time
- The life forms that lived in each era
Why: the geologic time scale marks boundaries by major events (like mass extinctions) and lists the characteristic organisms for each interval. The age of the Earth comes from radiometric dating (not just reading the scale), and the number of eras is a human-made count shown on the chart but not something the scale itself "determines."
