Passage:
For over five centuries, the master dyers of Kofar Mata in Kano have used natural indigo, ash lye, and potassium hydroxide to stain hand-woven cotton fabric in deep earthenware pits. Traditionally, the longevity of the indigo solution relied on an uninterrupted fermentation cycle maintained by daily manual stirring and precise additions of cooked cassava starch. However, recent economic pressures and the influx of synthetic, cheap imported textiles have forced many young apprentices to abandon the craft for urban commercial driving. To survive, the remaining elder artisans recently partnered with a local technical institute to automate the pit aeration process using low-voltage solar pumps. While this technological intervention stabilized the bath fermentation without compromising color fastness, output remains constrained by the time required for traditional sun-drying on open earthen grounds during the humid monsoon months. Consequently, despite achieving chemical consistency and reducing manual labor, the guild cannot meet large-scale commercial export orders during the rainy season.
Based on the passage, what can be deduced about the primary limitation preventing the dyer guild from meeting year-round commercial export demands?
- Weather-dependent drying methods create a seasonal bottleneck that technology in the dyeing pits alone cannot overcome.Cevap
- BThe adoption of solar pumps degraded the traditional color fastness and chemical stability of the indigo dye.
- CThe elder artisans' stubborn refusal to introduce modern technology is the principal cause of their financial hardship.
- DThe migration of young apprentices to commercial driving is the direct cause of seasonal production halts in the rainy months.
