What body of water separates france and england?

The English Channel is your answer.

The English Channel is a fairly narrow (but not extremely) stretch of water, in which one can view France from the UK (and vice versa). This stretch became extremely well known with the Allies retreat from Dunkirk in the beginning of WW2

hope this helps

the group i'm selecting: greeks.

a first group of greek immigrants came to the us in the 1850s. the second group came to america starting in the 1890s due to economic opportunities they didn't have back in their home caused by the hardships of ottoman rule. greek immigration was 90% male, many of them expected to work and return to greece after earning enough capital, but ultimately had to remain in the us after the greek genocide.
