The statement that best illustrates an important difference in the values of Sparta and Athens is:
"Sparta preferred a culture that was free while Athens preferred a culture where people obeyed orders."
However, it's worth noting that this statement may reflect the values in a more nuanced manner. In reality, Sparta emphasized discipline and obedience among its citizens, particularly in the context of military training and societal roles. In contrast, Athens valued democracy, individual expression, and intellectual exchange, making it a center for arts, philosophy, and debate.
If you have to choose from the provided statements, the key distinctions lie primarily in the differing values surrounding personal freedom and governance, so make sure to evaluate the wording carefully.
