Final answer:
The reference materials do not provide a definitive answer to what Esther said the snow in Lodz meant in the book 'Resistance.' Snow in that context might symbolize many things such as danger, hardship, or a faint hope for the end of the war.
Step-by-step explanation:
In the context of Resistance, when Esther speaks of the snow in Lodz, she is likely referring to the dire conditions and the heavy atmosphere of the period during World War II, especially in the ghettos and concentration camps. Given that snow can often symbolize a blanket of quiet and change, it might be seen by those in the ghetto as a sign of the encroaching Germans, the onset of more severe conditions in terms of survival, or, paradoxically, a thin veil of hope that the war was nearing its end. However, the answer to the question is not explicitly found in the provided reference material. For a definitive answer to what Esther said the snow in Lodz meant, one would need to refer to the specific text in the book titled Resistance.
