Examine the table and answer the following question: which of the following statements best groups these ideas together?
anti-semitism
german nationalism
mein kampf

a. factors influencing the nuremburg trials
b. factors leading to the nazi holocaust
c. factors leading to the german invasion of poland
d. factors influencing the rise of the social democrat party

The three ideas are connected to the Nazi-Germany and Adolf Hitler, the author of Mein Kampf. The party in power was the Nacional Social Democratic Worker's Party  - so we reject option d). 

the Nuremberg Trials were trails of the Nazis, but not by the Nazis, so we can also reject this option.

the other two options are similar and related, but the invasion of Poland was not connected to anti-semitism, so so the correct answer is B.
