Final answer:
The higher quantity sold and higher price of caviar in the mid-1990s can be attributed to increased demand and decreased supply.
Step-by-step explanation:
The higher quantity sold and higher price of caviar in the mid-1990s can be attributed to increased demand and decreased supply. The renewed interest in caviar coupled with a shrinking supply of Russian caviar after the collapse of Soviet Communism led to an increase in demand. At the same time, the decrease in the supply of Russian caviar contributed to the overall decrease in the availability of caviar in the market, leading to higher prices.
