Dr. Krell combines a very personal narrative with statistics on the
Holocaust. What does this combination accomplish? How do both
aspects of the discussion paper complement one another?

Giving personal experiences along with data works as an evidence and factual information making the statements of the narrative even stronger and providing more clarity.

Explanation:

Dr Krell combines the experiences that he had to go through during the time of holocaust. It was all his personal experiences that how tough the life was at that time and people had to go through so much. There were so many murders and killing happening at such a large scale of the Jewish community people in Jerusalem.

A lot of people had to immigrate from their original position and had to resettle down some where else so that they could start a fresh life and save their lives.
