Direction for the following 7 (seven) items: Read the following seven passages and answer the items (61-67) that follow the passages. Your answers to these items should be based on the passages only.

A landscape-scale approach to land use can encourage greater biodiversity outside protected areas. During hurricane ‘Mitch’ in 1998, farms using ecoagricultural practices suffered 58 per cent, 70 per cent and 99 per cent less damage in Honduras, Nicaragua and Guatemala, respectively, than farms using conventional techniques. In Costa Rica, vegetative windbreaks and fencerows boosted farmers’ income from pasture and coffee while also increasing bird diversity. Bee pollination is more effective when agricultural fields are closer to natural or seminatural habitat, a finding that matters because 87 per cent of the world’s 107 leading crops depend on animal pollinators. In Costa Rica, Nicaragua and Colombia silvopastoral systems that integrate trees with pastureland are improving the sustainability of cattle production, and diversifying and increasing farmers’ income.

Which among the following is the most logical and rational inference that can be made from the above passage?

Correct Answer: Agricultural practices that enhance biodiversity can often increase farm output and reduce the vulnerability to disasters.

Step-by-Step Explanation:

Step 1: Analyze the passage
The passage highlights several positive outcomes resulting from ecoagricultural practices and systems that enhance biodiversity outside protected areas:
1. Disaster Resilience: During Hurricane 'Mitch', farms using ecoagricultural practices suffered significantly less damage (58% to 99% less) compared to farms using conventional techniques.
2. Increased Farm Output / Income: Vegetative windbreaks and fencerows boosted farmers' income from pasture and coffee in Costa Rica. Additionally, silvopastoral systems (trees integrated with pastureland) diversify and increase farmers' income while improving sustainability.
3. Pollination Benefits: Proximity to natural/seminatural habitats makes bee pollination more effective, supporting crop yields for the majority of the world's leading crops.

Step 2: Evaluate the Options

• Option 1 ("Agricultural practices that enhance biodiversity can often increase farm output and reduce the vulnerability to disasters."): This statement accurately synthesizes all key points of the passage. Reduced damage during Hurricane Mitch demonstrates reduced vulnerability to disasters, while boosted farmer income and effective pollination demonstrate increased farm output. Therefore, this is the most logical and rational inference.

• Option 2 ("All the countries of the world should be encouraged to replace ecoagriculture with conventional agriculture."): Incorrect and contradicted by the passage. The text shows ecoagriculture performs better than conventional techniques, so replacing ecoagriculture with conventional agriculture would be harmful.

• Option 3 ("Ecoagriculture should be permitted in protected areas without destroying the biodiversity there."): Incorrect. The passage specifically talks about encouraging greater biodiversity outside protected areas, not introducing ecoagriculture inside protected areas.

• Option 4 ("The yield of food crops will be very high if ecoagricultural practices are adopted to cultivate them."): Incorrect. Claiming the yield will be "very high" is an overgeneralization and too extreme, whereas Option 1 uses the appropriately nuanced word "often".

Conclusion:
Hence, the most logical and rational inference is that agricultural practices that enhance biodiversity can often increase farm output and reduce vulnerability to natural disasters.
