45. What measure did Themistocles take to prepare Athens for a likely war with Persia?

Answer: C

Explanation:

He increased the size of the Athenian navy.

To prepare Athens for a likely war with Persia, Themistocles focused on increasing the size of the Athenian navy, recognizing the strategic importance of naval power in defending the city and projecting strength against potential invaders.

A) He borrowed money from neighboring city-states to pay for arms

While securing financial resources is crucial for military preparedness, this option does not directly represent the key measure taken by Themistocles. His emphasis was primarily on enhancing naval capabilities rather than borrowing funds from neighboring states.

B) He formed a close alliance with the Phoenicians

Forming an alliance with the Phoenicians is not documented as a significant action taken by Themistocles. Instead, his focus was on strengthening Athenian naval power and fostering relationships with other Greek city-states, which made this option incorrect.

C) He increased the size of the Athenian navy

This option is correct because Themistocles recognized that a powerful navy was essential for Athens to defend itself against Persia. By expanding the fleet, he aimed to ensure that Athens would have the maritime strength needed during conflicts.

D) He strengthened Athens' alliances with the Greek colonies

While strengthening alliances could have been beneficial, it was not the primary measure taken by Themistocles in preparation for war. His main focus was on enhancing the naval fleet, making this option less relevant to the question.

Conclusion

The correct answer is that Themistocles increased the size of the Athenian navy, as this was a pivotal strategy in fortifying Athens against Persian threats. Other options, while potentially beneficial in their own right, do not capture the essential military focus that Themistocles prioritized in order to secure Athens’ defense and enhance its naval power.
