Pure Research Problem Identification

The core difference between pure and applied research lies in their objectives.

• Pure research (or basic research) aims to expand knowledge and understanding of fundamental principles, driven by curiosity.
• Applied research aims to solve specific, practical problems or address real-world needs.

Analyzing Research Problems

Let's examine each option:

• Option 1: Vocational interests of adolescent girls: This could be pure research (understanding adolescent psychology) but is often conducted to inform practical career guidance, leaning towards applied research.
• Option 2: Role of ICT's in empowering rural women: This focuses directly on solving a societal issue (empowerment) using specific tools (ICTs), clearly indicating applied research.
• Option 3: Estimating time and energy consumption in use of solar cooker: This involves measuring and understanding the performance characteristics of a device. The primary goal is knowledge acquisition about the process, fitting the definition of pure research. It seeks to understand *how* time and energy are used.
• Option 4: Entrepreneurial activities of rural woman: Similar to option 2, this addresses a practical socio-economic issue and aims to understand factors influencing these activities, making it applied research.

Conclusion on Pure Research

Option 3 is the most representative example of a pure research problem because its focus is on acquiring knowledge about the operational efficiency (time and energy consumption) of a solar cooker, rather than immediately solving a specific practical problem.
