Which term denotes service sector industries that require a high level of specialized knowledge or skill, such as high-level management?

• A. Quinary activity
• B. Quaternary activity
• C. Tertiary activity
• D. Secondary activity

Answer: (A)

High-level decision-making services fall into the quinary category, which groups industries and roles that require specialized knowledge and strategic leadership. This includes top executives, policymakers, and other roles that shape direction and make crucial organizational or national decisions. It’s different from quaternary activities, which are knowledge-based and focus on information processing, research, and development rather than directing organizations. Tertiary covers general service sectors like retail and hospitality, and secondary covers manufacturing and processing. Because the prompt emphasizes specialized knowledge and high-level management tasks, quinary best fits.
