C and A
Because on A persia did lose on C it was called the first attack on Persia. I don’t think D is one because the Greeks won the battle.
Because time is a social construct. It was only created when civilization was created. Since there was no one to create time in the beginning of Earth we had to create it as far back as we could. So basically science as stuff created time to help people. Time wasn't a thing back then. It only became a thing when people became a thing.
Hope this Helps!
Conflict, while often avoided, is not necessarily bad. In fact, conflict can be good for organizations because it encourages open-mindedness and helps avoid the tendency toward group think that many organizations fall prey to.
I hope this helps :)
