Final answer:
Deng Xiaoping replaced Mao Zedong's policies largely because of the disastrous outcomes of the Cultural Revolution and the Great Leap Forward, which caused economic depression and famine.
Step-by-step explanation:
Considering the events listed and the historical context, Deng Xiaoping likely replaced many of Mao Zedong's policies due to the negative outcomes of the Cultural Revolution and the Great Leap Forward. The Cultural Revolution, initiated by Mao in 1966, led to widespread violence, chaos, and the disruption of the Chinese economy. The Great Leap Forward, another policy of Mao's, intended to rapidly advance Chinese industry and agriculture, disastrously resulted in a famine that caused the deaths of millions. These events created an imperative for Deng Xiaoping to shift China's direction when he came into power after Mao's death.
