Answer:
The sensory details in the excerpt evoke a sense of awe and wonder
Step-by-step explanation:
The phrases the author uses to describe the setting ("was glimmering", "dropping magnesium-brilliant"), the way they describe the unknown origin of the lights ("but you could never see the source of the light") and describes the effect that the flares have: "it seemed as though anything caught in their range would be made still, like figures in a game of living statues", conveys that the narrator feels that they are in the presence of something unusual and marvelous, and those details evoke a sense of awe and wonder.
