Answer Details
A system in which one level of government exercises an overwhelming authority over others can best be described as a unitary system. In a unitary system, the central or national government has the power to make decisions on behalf of all other levels of government, such as regional or local governments.
Under a unitary system, the central government has the power to create or abolish regional or local governments, as well as to appoint their leaders. The central government also has the power to dictate policies and laws that affect all regions or localities within the country.
This centralized system of governance can be efficient and effective in certain circumstances, such as in countries with a relatively homogeneous population or a small geographic size. However, it can also lead to a lack of representation and participation at the regional or local levels of government, as well as potential conflicts between the central and regional or local governments.
In summary, a system in which one level of government exercises an overwhelming authority over others can best be described as a unitary system. Under this system, the central or national government has the power to make decisions on behalf of all other levels of government, potentially leading to a lack of representation and participation at the regional or local levels.
