Final answer:
The subject is English, with a focus on American Literature and the narratives suggest historical and human experience themes. The grade level is College, due to the advanced analysis required.
Step-by-step explanation:
The subject of these excerpts appears to be English, specifically American Literature, considering the narrative structures and storytelling techniques employed within the texts. These excerpts likely come from a range of American Literature, depicting scenes of historical significance or human experience. The diverse scenarios suggest a focus on themes like race, conflict, and the human condition within historical contexts. The college-level analyses of literature typically involve the dissection of themes, character motivations, narrative techniques, and historical contexts, all of which are present in these snippets.
The passages touch on various historical moments, such as the Colfax Massacre and Warsaw Ghetto, indicating a blend of literature with social studies. However, the subject remains English due to the context these events are presented in, which is literary rather than historical analysis.
The grade level is likely College, given the complexity of the content, which commands a higher level of critical thinking and interpretation from the reader.
