Answer:
The argument between Brutus and Cassius arises because Brutus accused Lucius Pella of taking bribes, while Cassius seeks to protect Pella.
Explanation:
Brutus believed that killing Caesar was either for justice and the good of Rome, or was hypocritical. Cassius complained about Brutus disciplining one of Cassius' subordinates, and Brutus in turn accused Cassius of taking bribes.
