Final answer:
The author's reaction to her mother's statement about the exclusion of colored people from streetcars in "Occupation: Conductorette" is not explicitly stated in the provided excerpts, hence a definitive answer cannot be given.
Step-by-step explanation:
In the context of the various excerpts provided, particularly the one mentioning "Occupation: Conductorette," it seems that the correct answer to the question as to the author's reaction to her mother's statement, "They don't accept colored people on the streetcars," is not explicitly provided in the available text. However, one may infer from the passage and other similar themes of racial identity and the struggle against racial prejudice in the excerpts, that such an exclusionary practice would likely provoke a strong emotional response. The author's reaction could thus plausibly be one of disappointment or being deeply hurt, considering the historical context of segregation and discrimination. Unfortunately, without specific text from "Occupation: Conductorette," I cannot confidently choose between A. She is furious, B. She is disappointed, C. She is deeply hurt, or D. She is amused.
