Final answer:
The true or false statements provided about the salvation of the warder in "Totentanz" cannot be verified as no specific context is provided within the known narratives of the 'Dance of Death', and the excerpts shared from other texts do not confirm any of the options.
Step-by-step explanation:
The student has asked a series of true or false questions about how the warder is saved in the story "Totentanz". None of the options provided directly relate to any widely known narrative called "Totentanz", which generally refers to the 'Dance of Death' theme in medieval European art and literature. The provided excerpts from various texts reference supernatural and macabre themes but do not give enough context to affirm any of the specific scenarios about the warder's salvation.
Therefore, without additional information, it is not possible to determine the correctness of each statement. The assertion in option a) about returning a stolen shroud, b) about a bell tolling and the skeleton turning to dust, c) about the dead returning to graves, and d) about a sorcerer and enchanted brooms, resemble various other literary works or folkloric elements but do not specify a source related to "Totentanz" that would confirm their truth.
