As if you would have done A!
Part B was so much easier to elaborate on.
The question one chose probably depended on the emphasis the teacher placed on the topic. My teacher placed particular emphasis on the Persian Wars so our school cohort did A, even though B was also doable.
For A:
- Role of of Themistocles in diverting funds from Laurion to the construction of additional triremes
- strategy of keeping persians in convoluted straits offset numerical disparity**
- Themistocles sowed seeds of dissension at artemisium by leaving messages at Xerxes supply depots telling the medisers to fight badly (Herodotus)**
- Themistocles deception of Xerxes at Salamis, causing the Persians to be led into waters favorable to the Athenian navy and it's other contingents.
- overall power and strategy of the triremes
For B:
- establishment of cleruchies, uniform coinage, and movement of treasury to Athens
- Athens use of force to suppress seceding poleis (Naxos and Thasos)**
- Poleis who could not pay tribute had to plead cases in the Athenian law courts
- chalcis decree and swearing of oath's**
Etc
Both were overall doable, remember, a lot of people probs specialised...**
