read the excerpt from rena kornreich gelissen’s rena's promise: two sisters in auschwitz. that night changed everything. it had become dangerous for me to live in tylicz. . . . papa deliberated long and hard over whom to contact about smuggling me across the border. andrzej had been fighting the germans when poland had first been invaded, but he’d been fortunate enough to escape capture; returning secretly to tylicz, he was now working for the polish resistance. who knew the border better than andrzej?... "i have a favor to ask of you, andrzej . . . this is very difficult for me, but i must ask. it is no longer safe in tylicz for rena. her mother and i are worried for her safety every day." what assumptions can be made about the setting described in the excerpt?
