The nuremberg laws identified a jew as someone who
went to synagogue every week.
celebrated the jewish holy days.
had jewish ancestors.
had traveled to palestine.

The answer is "Someone who had Jewish ancestors."

Explanation:

In order to define Jews before the law, Nazi legislators went back to people´s genealogy. Anybody with three or more grandparents born into the Jewish religious community were legally considered Jews. Those ancestors were seen as "racially Jewish" and that "status" was passed onto their children and grandchildren.
