The correct answers are "It grew out of work of a statesman named Solon".
Solon wanted to promote a system that pushed equality and active participation from all citizens in government. He gave Athenians the right of serving in assembly gatherings. These changes represented a significant cange of paradigm to a certain extent towards democracy in Greece.
Every citizen of Athens who owned some kind of property was able to participate in the assembly. Even though you were poor, you could still own a house and be able to serve politically,
Athenians who were in a situation of debt, were restrained from voting but they weren't enslaved. The only slaves they had at the time were foreign.
All males who owned property were free to serve but not obligated.
You could say Greek democracy set things up for an improvement towards political equality, but still continues to be seen as a sort of "collective tyranny". Political decisions were made by majority vote, and this often led to the poor overpassing common welfare, rendering the system a false democracy. So even though Greek democracy did push many advances, it also had plenty of crucial flaws it couldn't overcome.
Hope this helps!
