Answer:
Countries with a federal form of government face challenges related to coordination and potential conflicts between central and regional authorities. For instance, in India, there have been disputes between the central government and states over issues like control of resources and distribution of funds.
Additionally, ensuring uniformity in laws and regulations can be challenging due to diverse regional needs and interests. In Brazil, the federal structure has led to inefficiencies in public administration and service delivery due to overlapping responsibilities.
Moreover, disparities in economic development between regions can create tensions and hinder national progress. Overall, effective cooperation and communication between federal and regional governments are essential to overcome these challenges and maintain a stable federal system.
