The three social classes in ancient Sparta were: the Spartiates (free citizens with full rights), the helots (slave employed in production activities), perioeci (free citizens that wandered around, <em>"dwellers around",</em> who were mainly traders or craftmen).
Spartiates dedicated their lives fully to becoming high quality professional soldiers, as actually military activities which were the common objective of the whole society. Since they were children they were educated by the state-sponsored education system, the Agoge, that fostered values such as obedience, discipline, courage, loyalty to Sparta, self control, etc.
It increases the turnout of voters. This is because they now project an image of
hope and strength when they are stronger.
This encourages more support from their base and may even attract voters
who are not part of their party.
I would probably ask my teacher to remake the test!
