Diamond sources started appearing in South Africa after the:

• A. 1780s
• B. 1860s
• C. 1900s
• D. 1950s

Answer: (B)

Timing of the first diamond sources appearing in South Africa is what this question is testing. Diamonds began to show up in South Africa in the 1860s, not earlier or much later. A stone found along the Vaal River in 1867 sparked the realization that diamond-bearing deposits existed in the region. Soon after, the Kimberley area turned up extensive diamond-bearing gravels, and mining there began in the early 1870s. So, the 1860s is the correct window because it marks the moment when diamonds first became known and accessible in South Africa. Earlier decades like the 1780s aren’t correct, and the 1900s or 1950s come after mining had already started.
