Hello. You have not indicated which text the question refers to. This makes it impossible for the question to be answered efficiently and satisfactorily.
However, a section called "The Holocaust" should provide context for a line that refers to the cruelty that the Nazis inflicted on Jews, Poles, Sigans, prisoners of war and other people who were persecuted and subjugated by Nazis, especially Jews who were almost exterminated during the holocaust.
In this case, to find the answer to your question, you need to read the opening text and find the section that points to these elements.
The easiest part of the exercise, personally were the push-ups. I find push-ups the easiest because I don't get tired that easily compared to other exercises like pull-ups, etc. I found push-ups being my favorite exercise in this set because they're really good for your arm and shoulders, pectorals and deltoids. Push-ups are also easy for me because they're one of the most repetitive, basic exercises but they're good because they use your body against yourself.
Anne Frank<span> has been called the "human face of the Holocaust." The diary she kept for 25 months, when she was in hiding from the Nazis, is a life-affirming record of her spirit and hope in the face of cruelty and danger</span>
