Final answer:
Hannah may not dare to turn to look at the men behind her due to fear, suspense, or a sense of foreboding, which is a common literary trope.
Step-by-step explanation:
The passages provided suggest a variety of reasons why Hannah might not have dared to turn around to look at the men getting into line behind her. From a literary point of view, such a reaction can often be attributed to fear, suspense, or a response to a mysterious or threatening situation, where looking back could have dire consequences. For instance, a character might refrain from looking back due to a warning, as in the given excerpts, or out of a sense of foreboding or anticipation that something irreversible might happen should they give in to the temptation to look. The common trope in literature of not looking back carries connotations of moving forward and not dwelling on the past or on potential dangers lurking behind.
