Final answer:
Marcus starts the passage feeling agitated around soldiers, but as the situation escalates, he becomes more aggressive, culminating in an act of violence when he throws a knife.
Step-by-step explanation:
From the beginning to the end of the passage, Marcus undergoes a significant transformation in response to the soldiers. Initially, Marcus exhibits signs of unease and agitation: he becomes more agitated as evidenced by his restless movements and growling in response to the soldiers. However, as the situation escalates, Marcus's behavior shifts from discomfort to a more confrontational stance. In one of the excerpts, Marcus's potential for violence is underscored when he throws his knife in an aggressive act, which suggests that he gets more aggressive toward the soldiers. Throughout the various passages, there is no mention of Marcus growing less compliant or ceasing his attempts to explain. Instead, the extracts depict a character who is increasingly driven by his emotions, moving towards a hostile reaction in the face of conflict with the soldiers.
