Question

chinas agricultural policies during the great leap forward led to
crop failures, causing famine that killed millions of people.
increased crop production that helped feed millions of people.
crop failures that cost the government millions in subsidies.
increased crop production that raised millions in exports.

Explanation:

The Great Leap Forward's agricultural policies, including forced collectivization and unsustainable farming methods, resulted in widespread crop failures. This led to a severe famine that caused the deaths of millions of people. The other options are incorrect as production did not increase, and the primary consequence was mass loss of life, not subsidy costs or export gains.

Answer:

crop failures, causing famine that killed millions of people.
