Maybe the third and second question
Answer: Know—In the Holocaust, Jews were persecuted by Nazi Germany.
Know—Jews in Germany often hid in the homes of people willing to shelter them after it was too dangerous to try to escape the country.
Know—During the time of the Holocaust, food and necessities were strictly rationed. Each family was given ration cards and could turn them in for their allotted food for a period of time (usually a week, sometimes longer).
Know—Jews who were discovered were taken to concentration caps where they were tortured and killed.
Know—Families who harbored Jews were taken to the camps as well, or sometimes, killed immediately upon being discovered.
(This next part you can literally write anything you want to know, there's not a right answer, but I'll give some examples).
Want to Know—How many Jews survived the concentration camps?
Want to Know—Were there Nazi soldiers who secretly helped the Jews?
Want to Know—Did any families like Anne Frank's survive the Holocaust without being found?
Want to Know—Did people who told the Nazis about locations of Jews who were hiding get rewarded?
Hope this helps!
