A group of friends are discussing their ancestors for a school project. They all have an ancestor who lived in Germany during the 1930s. After the Nazis came to power,
Tom's ancestor was killed, Jim's ancestor was imprisoned for many years, and Bob's
ancestor was forced into exile and unable to return to Germany until the Nazis were
out of power. What would account for the treatment of the friends' German
ancestors?

O They were all Aryans, which made them undesirable in Germany.

O They spoke out against the Treaty of Versailles.

O They were members of a communist group.

O They supported Adolf Hitler's rise to power.
