Read the passage below carefully and answer the question that follows:
Tin mining on the Jos Plateau in Nigeria began commercially under British colonial administration in 1905, following early geological surveys by Sir William Wallace. Prior to European involvement, local blacksmiths in the region had already mastered small-scale smelting of cassiterite ore obtained from local riverbeds. The colonial government established the Minerals Ordinance of 1907 to regulate mining concessions, which led to a rapid influx of foreign mining companies. By 1928, the Jos Plateau supplied over ten percent of the world's total tin output. Mining operations relied heavily on labor migrated from northern and central provinces, which significantly altered the demographic landscape of Jos town. However, large-scale open-cast mining caused extensive environmental degradation, leaving deep pits filled with water and removing vast areas of arable farmland across the plateau.
According to the passage, what was the primary reason for establishing the Minerals Ordinance of 1907?
- ATo prohibit indigenous blacksmiths from extracting cassiterite ore from riverbeds.
- To regulate mining concessions in the region.Answer
- CTo remediate environmental damage caused by deep water-filled pits.
- DTo manage the influx of migrated laborers coming from northern provinces.
