The correct answer is option C) Syr Darya River D) Amu Darya RiverThe two rivers that fed into the Aral Sea and were used for the irrigation project in 1918 were the Syr Darya River and the Amu Darya River.
In 1918, the Soviet Union's policymakers chose to divert fresh water from two major rivers in Central Asia for irrigation. This was a necessary component of their efforts to increase cotton production, which they referred to as "white gold," a significant Soviet export. The Soviet decision-makers understood that increased withdrawals from the rivers would cause the Aral Sea to shrink to a residual brine lake.
However, they felt that when the benefits of increased agricultural output were balanced against the ecosystem service benefits of the sea, the Aral's desiccation was warranted. The two rivers that fed into the Aral Sea and were used for this irrigation project were the Syr Darya River and the Amu Darya River, with a significant impact on the Aral Sea.
