Read the passage below carefully and answer the question that follows:
In recent years, smallholder farmers across southwestern Nigeria have increasingly adopted solar-powered flash dryers to process harvested cassava tubers into high-grade industrial starch. Traditionally, cassava processing relied heavily on open-air sun drying, a labor-intensive technique highly vulnerable to sudden rainfall and microbial contamination. While the introduction of solar flash dryers has significantly reduced post-harvest losses and boosted income levels for local cooperatives, the primary catalyst behind this widespread technological shift is the surging commercial demand from domestic food processing and pharmaceutical industries seeking locally sourced raw materials. Furthermore, government initiatives offering low-interest micro-loans have enabled rural agricultural unions to purchase these mechanized drying units. Despite minor challenges regarding routine mechanical maintenance, solar flash drying continues to transform rural cassava value chains by providing a consistent supply of industrial-grade starch to urban markets.
Which of the following best expresses the main idea of the passage?
- The transition to solar flash dryers in cassava processing is primarily driven by rising industrial demand for domestic starch.Cevap
- BTraditional open-air sun drying of cassava is a labor-intensive method prone to rainfall disruption and contamination.
- CLow-interest government micro-loans represent the primary catalyst behind farmers adopting modern drying equipment.
- DSolar flash dryers have completely eliminated post-harvest losses and operational challenges for rural cassava processors.
