Final answer:
The tone of the sentence is best described by feelings of fear and suspense, conveyed through the imagery of darkness and the protagonist's rising panic.
Step-by-step explanation:
The phrase that best describes the tone of the sentence 'The night clouds I'm scared of the silver off the moon that had eliminated Stevens path and panic begin to creep up his spine threatening to overtake his thoughts' would be one that encapsulates feelings of fear and suspense. The tone conveys a sense of fear through the description of the protagonist's rising panic and the dark, unsettling environment suggested by the mention of the 'eliminated' path. Furthermore, there's an element of suspense as the reader is left to wonder what may happen next to Stevens on his obscured path. These two key emotions - fear and suspense - are highlighted through the imagery of the moon and darkness as well as the physical reaction of panic creeping up Stevens' spine. It's these descriptive elements that evoke the intended tone within the narrative.
