A. the senate and house of representatives
The Qin adopted the legalism in warfare (against the other states). They crushed one state after the other. This phylosophy worked for them in war so they decided to continue with its principles in peace time. The Qin Dinasty reflected Legalist principles by enacting laws. It was a way to control the population of China and there were severe penalties for breaking the laws, including fines and conscription in the army.
