Beacause of sea waters and heights
Sparta, located at the extreme south of the Balkan peninsula was favored by its landscapes. Possessing large areas of fertile land, it had a self-sustained agriculture, and could afford having restrict commerce policies. Therefore, <u>they did not depend on sea commerce to survive</u>.
Athens, on other hand, was marked by uneven landscapes, unfit for farming, therefore depended a lot on commerce and because of that, expanded its trades throughout the Aegean Sea, with the islands and coastal cities around it, that would benefit greatly from this.
Hope this helps
One government reform enacted in the Chinese Tang dynasty was its emphasis on education. It was one of the reforms that contributed the dynasty’s success. The Tang rulers did not feel that a well-educated people is a threat to the government. For the rulers, an educated public is a foundation of a stable and prosperous society. Unlike other forms of government who feared intellectuals, the Tang dynasty embraced knowledge and education, thus, encouraging its people to have a form of education.<span> </span>
It's kinda like an educated guess.
