A less developed country earns income by exporting copper. This income helps fund roads and schools, but copper is its main export and extraction pollutes local water.
Which is the best assessment of the effects of these copper exports?
Selling copper abroad lowers the risk of relying on one mineral, because foreign buyers replace local demand
The export earnings could support lasting development, but dependence on copper and water pollution put this at risk
Relying mainly on copper makes export earnings a more dependable source of funding than a range of exports
Polluted water lowers local welfare, but it need not weaken sustainability while copper export income stays high
