Could you please paraphase this?

Paraphrasing means putting it into your own words without losing the meaning of the text. For example: In the first one it could be written as "The SS arrested 30,000 Jews and put them in concentration camps where they were treated very harshly. Since this is only one sentence with a lot of factual information it won't change much. A longer piece, like the last one would change a little bit more.
