Part 1:
1. Country A is using a unitary system of government.
Part 2:
2. The evidence for my answer is that Country A has a strong central government and the states rely on the central government for money and support. This suggests that power and decision-making authority are concentrated in the central government rather than being divided or shared among multiple levels of government. Additionally, the description mentions that the legislative branch can make laws, indicating that there is a centralized authority responsible for creating and enforcing laws at the national level.
