Final answer:
The question seems to seek a summary of 'the black heel,' which is not distinctly identified in the excerpts but appears to relate to the African American experience. Excerpts hint at themes of racial struggle, emancipation, and African American literature.
Step-by-step explanation:
The request seems to be asking for a summary of content related to African American experiences and narratives, possibly touching upon literature or history connected to racial struggles and emancipation. Although the excerpts provided are varied, they do not specify a particular work titled 'the black heel,' making it difficult to provide a precise summary. However, the excerpts do contain elements related to African American literature, such as allusions to works like The Souls of Black Folk by W.E.B. Du Bois, which discusses the experience and consciousness of African Americans in the early 20th century. They also reference historical struggles like slavery and its long-lasting impact, suggesting the complexity of the black experience throughout history.
