The countries that existed in Ancient Greece were Athens, Sparta,
Thebes, Eretria, Corinth, Chalcis and Syracuse. Most notable of these
were the countries of Athens and Sparta, because it was the armies of
these countries that fought against the Persians during the war.
"George Washington was the first president of the United States" is the correct answer. This can be confusing, but president is not capitalized unless it is being used as a title, like "President Washington was the first president of the US"
