Examine the logical coherence between the following constitutional features and their comparative categorization:
1. Evidence 1: Part III of the Constitution shields citizens from the arbitrary actions of a tyrannical executive or legislature. Inference 1: Therefore, the primary objective of Fundamental Rights is to establish and secure a robust political democracy.
2. Evidence 2: Part IV outlines the ideal of a welfare state, promoting equal pay and wealth distribution. Inference 2: Consequently, Directive Principles are primarily focused on constructing social and economic democracy.
3. Evidence 3: A citizen cannot file a writ petition demanding the state to immediately provide them with an adequate means of livelihood. Inference 3: This demonstrates that Fundamental Rights require specific parliamentary legislation before they can be enforced by a court.
