The correct option is 1 only
Explanation
The tertiary sector, commonly known as the service sector, involves activities that support production and consumption through the provision of services rather than tangible goods. The "modern" tertiary sector has evolved to include highly sophisticated activities such as finance, information technology, healthcare, and professional consultancy.
Statement-wise Analysis:
- Statement 1 is Correct: The modern tertiary sector is characterized by a high degree of specialization. Services are often delivered by professionals with specific expertise, such as doctors, lawyers, teachers, and IT consultants, who require specialized training and education.
- Statement 2 is Incorrect: The modern service sector relies mainly on skilled labor and human capital, not unskilled manual labor. While some basic services involve manual labor, the "modern" aspect of the sector emphasizes knowledge-based and skill-intensive roles.
- Statement 3 is Incorrect: Information and Communication Technology (ICT) plays a foundational role in the modern tertiary sector. It enables the delivery of services across distances (e.g., BPO, tele-medicine, online banking) and improves efficiency. The role of technology is extensive and critical, not limited.
Key Takeaway:
The modern tertiary sector is distinguished by its reliance on specialized skills, professional expertise, and the intensive use of information technology to deliver high-value services.
