Final answer:
Without additional context, it is not possible to accurately determine what Mother believes happened to Life from the provided text excerpts. The texts cover themes like slavery, imprisonment, and wartime strategy, but do not directly address Mother's beliefs about Life's fate.
Step-by-step explanation:
The student's question about what Mother believes happened to Life refers to different possibilities regarding the fate of a character in a given narrative. Given the provided extracts, which discuss aspects of slavery, captivity, escape and the strategic considerations of the Allies during wartime, it seems that the question might be related to a historical novel or a text that takes place within a historical context.
However, without a specific reference to 'Mother' or 'Life' within the excerpts or additional context, it is challenging to determine which option (a, b, c, or d) accurately reflects Mother's belief. The available information does discuss the capture and imprisonment of individuals, the tactics of the abolitionists, and the conditions of those enslaved or held during times of war. Yet, the belief of 'Mother' about 'Life' cannot be accurately discerned from these excerpts alone.
Thus, to answer the student's question correctly, further context from the text in question would be necessary. This could include direct quotations or a clearer indication of who 'Mother' and 'Life' are within the narrative, as well as the specific circumstances surrounding Life's disappearance or situation.
