Final answer:
The passage provided contains sentence fragments such as "No, no," and "Hush yo' fuss, Eddy!" which contribute to the informal tone of the narrative.
Step-by-step explanation:
Within the passage provided, looking for additional sentence fragments similar to "Ten, twelve years?" and "And Dee.", we can identify other instances that contribute to creating an informal tone. These fragments include "No, no," and "Hush yo' fuss, Eddy!" These snippets lack the full structure of a complete sentence, often missing a verb or a subject, and this stylistic choice mirrors the way people sometimes talk in real life, thereby adding to the informal tone of the narrative.
