What are three things that Greece, Persia, and Rome all have in common?

Nearly nothing. There are differences, but they are small.

Roman society took much from the Greeks when they conquered them. The Romans were more into war then the Greeks (more into the sciences).

Persia was a better place to be a woman than Greece, and they were accepted as professionals (in some cases) in Persia, while in Greece they were confined to the house. Woman were also more important (though still less then Persia) in the Roman Empire.

As well, slavery didn't matter as much in Persia as Rome and Greece.

All three worshipped Gods in what we would now call a pagan religion. The Gods were different but had the same idea.

The first one is russia because in russia they were on the rough times and they never had a way to get out of
