The correct order of formal eons from oldest to youngest is:
hadean, archaean, proterozoic, phanerozoic.
The geological time scale include divisions of time. The eons are the primary divisions of time (the Hadean, the Archean, the Proterozoic and the Phanerozoic).

I thought I already answered this but anyways, the answer is A. Zebras will live and graze in herds. When a predator spooks the herd the zebras run as one. That ways it confuses let's say the lion because they see in black and white. To them they see racing stripes so it's hard for them to decide which zebra to take down. If running together backfires, the zebras will stand their ground and protect the weaker and younger zebras by kicking and biting the lions. Hope this helps!
