Final answer:
Marji likely broke her parents' rules as a form of asserting independence and was possibly influenced by a complex mix of emotions, similar to the characters in the provided excerpts.
Step-by-step explanation:
Marji's motive for breaking her parents' rules stems from her desire to assert her independence and challenge authority. In the context of the provided excerpts, it seems that Marji, like other characters such as Bernice and Jane Withersteen, is driven by a complex mix of emotions and personal desires that lead to actions that defy expectations or societal norms.
In the excerpts, we observe characters like Marjorie who exhibit a strong sense of self and confidence in their actions, suggesting that Marji might also be influenced by a similar confidence when breaking her parents' rules.
Violations of trust occur when characters act on their emotions or desires, which often leads to conflict and dramatic confrontations, as seen in the interactions between Marjorie and Bernice, and Jane Withersteen's intense emotional reaction.
