Correct Option (d)
The passage comprehensively outlines the global nature of the food security challenge, detailing how population growth, consumption patterns, climate change, and resource limitations necessitate collective action. It suggests solutions involving both "poor countries" and "rich nations," thereby emphasizing that food security is a shared, international responsibility requiring coordinated efforts.
Incorrect Options:
The passage mentions population growth as a premise but primarily focuses on the multifaceted challenges and solutions related to food security arising from this growth, rather than merely stating the fact of rapid population increase.
The passage explicitly assigns responsibilities to both "poor countries" (improving crop storage and packaging) and "rich nations" (reducing resource-intensive food consumption). This indicates that the challenge of food security is global and not confined solely to developing economies.
The passage does not assert an inherent insufficiency of resources. Instead, it proposes various strategies, such as higher-yielding crop varieties, efficient farming methods, waste reduction, and dietary shifts, as means to address future food demand, implying that solutions are available.
