The correct option is 1 and 3 only.
Explanation
Infrastructure refers to the supporting services in the main areas of industrial and agricultural production, domestic and foreign trade, and commerce. It is the support system on which the efficient working of a modern industrial economy depends. It is broadly classified into Economic Infrastructure (associated with energy, transportation, and communication) and Social Infrastructure (associated with education, health, and housing).
Statement-wise Analysis
- Statement 1 is Correct: Infrastructure provides essential supporting services that facilitate production activities in agriculture and industry. For example, roads and railways transport raw materials and finished goods, while irrigation facilities support agricultural output.
- Statement 2 is Incorrect: The definition of infrastructure is not strictly limited to physical structures like roads, bridges, and power plants. It also encompasses Social Infrastructure, which includes the educational system, healthcare facilities, and sanitary systems. These contribute to the development of human capital, which is intangible but essential for economic progress.
- Statement 3 is Correct: Infrastructure facilities have a direct impact on the production of goods and services. Inputs such as power, water, and transportation are intrinsic to the production process. Without these facilities, the production of goods would be severely hampered or impossible.
Key Takeaway: Infrastructure is not merely physical construction; it includes both Economic Infrastructure (energy, transport) which directly supports economic activity, and Social Infrastructure (health, education) which improves the quality of human capital.
