Answer 1

I don't have the excerpt — could you paste it here? Without it I can't choose reliably.

If you want to decide on your own, look for these clues in the excerpt:
- Pick "the rationale for the Holocaust will always be incomprehensible" if the author says we can never understand or justify the Holocaust, or calls it unfathomable/inscrutable.
- Pick "history is likely to repeat itself if past events remain unresolved" if the author warns that failure to reckon with the past leads to repetition or ongoing dangers.
- Pick "there have been few mentally competent leaders throughout history" if the author criticizes leaders’ sanity or competency broadly.
- Pick "understanding the past enabled him to move on with his life" if the author describes a personal narrative where learning about history helped the individual heal or move forward.

Paste the excerpt and I’ll pick the best answer and explain why.
