Final answer:
Rebellion in Marji's generation is attributed in literature to hereditary traits, societal pressures, and personal struggles. Rebellion manifests both as resistance to one's own lineage and internal conflicts, as well as collective discontent such as in Shays' Rebellion over economic hardships.
Step-by-step explanation:
The question about why Marji's generation was so rebellious and what the teacher blames is addressed in literature, particularly through the lenses of social commentary and historical background. In the provided texts, the rebellious nature is often attributed to hereditary traits, societal pressures, or the various personal struggles individuals face.
For example, the excerpt referencing McTeague touches upon the theme of inevitable hereditary evil that one cannot understand or escape, suggesting a form of rebellion against one's own lineage. Meanwhile, in the case of Jarrett, the conflict emerges from a personal struggle and the expectation to set an example for his daughter, showing rebellion can also be internal, against one's own excuses or perceived failures.
In the broader context of social studies, instances like Shays' Rebellion mentioned in the last excerpt demonstrate collective discontent against economic pressures, where a group led by Daniel Shays revolts due to the burden of debt on farmers, symbolizing a struggle for economic justice and against governmental inadequacy. In all narratives, the underlying reasons for rebellion are complex, often deeply personal or rooted in systemic issues, from the microcosm of familial expectation to the macrocosm of national distress.
