Role of industrial exhibitions in economic progress: Regular exhibitions (e.g., in Delhi) allow a country to benchmark its comparatively less advanced industries against the powerful showcases of developed nations like the U.K., U.S.A., and Russia, drawing great attention and enabling analytical comparisons; the passage best supports which conclusion about such exhibitions?

Given data

• Exhibitions showcase domestic progress and the powerful industrial capabilities of developed nations.
• They draw attention and provide comparative exposure.

Concept/Approach (benchmarking logic)Seeing advanced products and processes creates benchmarks and learning opportunities, encouraging domestic industries to upgrade quality and scale.

Step-by-Step reasoning1) Measurement: Exhibitions let us “measure” our progress relative to leaders.2) Learning: Comparative assessment identifies gaps in technology, quality, and productivity.3) Outcome: Closing these gaps improves both quality (better products) and quantity (higher output).

Verification/Alternative checkThe passage never claims exhibitions harm poor economies or help only developed nations; rather, it implies a positive, catch-up role for developing countries.

Common pitfallsAvoid defeatist interpretations that exhibitions are “not useful” to backward economies; the text frames them as learning platforms.

Final AnswerExhibitions boost production both qualitatively and quantitatively by enabling analytical comparison with products of developed countries.
