Answer:
B) to inform readers about the tactics Sparta and Rome used to hold cities and their effectiveness
Step-by-step explanation:
In the passage from chapter 5 of The Prince, Machiavelli lists the cities conquered by Sparta and Rome . He then describes how Sparta had held Greece . Also in the passage is the explanation of how Rome dismantled Greek cities. These details all support Machiavelli's secondary purpose in writing this passage. He uses this secondary purpose to help support the primary purpose: to persuade readers that a conquering prince must destroy a former republic if he hopes to hold it.
