The Jews of Sighet ignored the reality of their perilous circumstances due to denial, lack of information, and fear.
Step-by-step explanation:
The Jews of Sighet in Poland ignored the reality of their perilous circumstances following the arrival of the German soldiers due to a combination of factors. First, many Jews were in denial and found it difficult to believe that such atrocities and discrimination could be taking place. Additionally, there was a lack of information and understanding about the extent and organized nature of the genocide. Finally, some Jews may have been reluctant to accept the dire situation out of fear or a sense of helplessness.
