Which diamond mine's huge production influenced the world market in the late 1980s?

• A. Argyle
• B. Letseng
• C. Diavik
• D. Ekati

Answer: (A)

A single mine can move the whole world market when its output swells, because more rough diamonds hitting the market changes supply, prices, and buyers’ expectations. The Argyle diamond mine in Western Australia produced a massive volume of rough diamonds during the mid-to-late 1980s, making it a dominant supplier globally at that time. That surge in production is what shaped market conditions in that period, more so than the other mines listed, which did not match that level of output then or opened production later.
