Final answer:
The word that best summarizes the tone of the passage from "The Star" is 'panicked,' as the passage conveys a sense of urgency and fear with vivid descriptions of chaos and dread. The correct answer is option d.
Step-by-step explanation:
The word that best summarizes the tone of the passage from "The Star" by H.G. Wells is panicked. This determination is made by analyzing the language and imagery used throughout, which suggests a sense of urgency and fear. The passage details how cities are alight, shipyards glared, and people crowded onto ships, all actions driven by the warning telegraphed worldwide about Neptune and another body hurtling towards the sun. Such vivid descriptions evoke a feeling of chaos and dread, pointing towards a panicked mood rather than excitement, indifference, or optimism.
