Answer: Recovering destroyed farms and cities under a new communist economy
Explanation:
The Vietnam War finally ended in 1975 when the North Vietnamese army captured Saigon and reunited the North and the South of the country into one single nation under a communist government.
The war had been very devastating on the Vietnamese as the U.S. bombed cities in the North and the battles in the South left cities and rural areas destroyed. The new Communist government therefore had to recover these destroyed cities and other farms in order for Vietnam to start working again.
