Read the passage below carefully:
For generations, the traditional tanners of the Kofar Wambai quarters in Kano relied on synthetic chromium salts to expedite the tanning of goat hides. While chromium significantly reduced processing time from weeks to mere hours, the toxic effluent drained into neighboring waterways, severely contaminating local soil and water tables. Recently, facing stringent environmental compliance standards imposed by international leather importers, a cooperative of master tanners reintroduced a refined tanning liquor derived from the pods of the native Acacia nilotica (bagaruwa) tree. Although the botanical process extends tanning time to several days and requires precise temperature regulation, the resulting leather commands a premium price in eco-conscious luxury markets. Interestingly, older tanners who had resisted chromium adoption four decades ago possessed the forgotten knowledge of balancing bagaruwa concentration with native lime solutions. Consequently, the cooperative appointed these elders to supervise quality control, effectively shifting the community’s economic reliance away from hazardous chemical imports while preserving traditional ecological expertise.
Which of the following inferences is logically supported by the passage above?
- International environmental regulations indirectly facilitated the revival and integration of traditional community expertise.Cevap
- BThe transition to botanical tanning reduced the overall time required to process goat hides relative to chromium methods.
- COverseas leather buyers funded the initial introduction of synthetic chromium salts into Kano four decades ago.
- DOlder tanners opposed chromium tanning decades ago primarily because it produced lower-grade leather than bagaruwa extracts.
