Answer :

The silver market dropped sharply in the 1980s, impacting Bolivia's income significantly. This decrease was a result of the global economic conditions during that period. The 1980s marked a challenging time for silver prices, leading to a decline in Bolivia's revenue from silver exports.

During the 1980s, various factors such as market speculation, decreased demand, and oversupply contributed to the sharp drop in silver prices. This downturn had adverse effects on countries like Bolivia, which heavily relied on silver exports as a significant part of their economy.

As a result, the 1980s stands out as the decade when the silver market experienced a significant decline, impacting Bolivia's income and highlighting the vulnerability of economies dependent on commodities like silver.
