The correct option is 1 and 3 only.
Explanation
The economy is structurally divided into three sectors based on the nature of activities: Primary, Secondary, and Tertiary. The Tertiary Sector, commonly referred to as the Service Sector, involves activities that generate services rather than tangible goods.
Statement-wise Analysis:
- Statement 1 is Correct: The core function of the service sector is to support the primary and secondary sectors. Activities such as transport, trade, storage, banking, and communication do not produce goods themselves but are essential for the movement, financing, and distribution of products generated in the agricultural and industrial sectors.
- Statement 2 is Incorrect: The service sector is not limited to production-support activities. It encompasses a wide range of essential services provided by professionals and workers who do not directly assist in the production of goods. This includes doctors, teachers, lawyers, barbers, and administrative personnel.
- Statement 3 is Correct: In the modern economic landscape, the definition of services has expanded to include technology-driven sectors. Services based on Information and Communication Technology (ICT), such as software development, internet cafes, ATM booths, and call centers, have become significant contributors to the sector's growth.
Key Takeaway:
The Service Sector includes both production-support services (transport, banking) and personal or professional services (healthcare, education), distinguishing it from the goods-producing sectors by the intangible nature of its output.
