Final answer:
The first paragraph of 'The House on Mango Street' helps develop the text by highlighting the narrator's disappointment with her actual living situation compared to her expectations.
Step-by-step explanation:
The description of the house in paragraph 1 of 'The House on Mango Street' primarily contributes to the text's development by reminding the narrator of everything that the house on Marengo Street doesn't have. The vivid imagery of the house, such as the bright orange marigolds and consistent layout, emphasizes the gap between the narrator's reality and the expectations set by the narrator's family. This contrast enhances the theme of disappointment and the struggle to find a place that the narrator can truly call home.
