Final answer:
The words 'Reins, shouted' and 'Stranger, chariot' most clearly create a frazzled and frantic tone in the story. These words, along with the provided descriptive excerpts, contribute to a tense and nervous atmosphere.
Step-by-step explanation:
The tone of a story is conveyed through the choice of words and the style of description that an author uses. From the given options, the words that most clearly create a frazzled and frantic tone are Reins, shouted (option C) and Stranger, chariot (option D). The action of someone shouting and the usage of 'stranger' teamed with 'chariot' inherently suggest drama or urgency, which aligns with a frantic atmosphere. On the other hand, Helped, daughter and Poor, caught might not evoke the same intensity of a frazzled mood.
Looking at the provided excerpts, the repetition and quick successions of actions such as grabbing and releasing the bell-rope and referring to the 'sepulchral cry' of the leadsman builds up this tense and nervous atmosphere. In another excerpt, the vivid description of the 'man shaking his fist at the child' and the 'clumsy multitude' moving 'in silence profound, absolute' further enhances the frantic mood through the imagery of chaos and desperation.
