Answer:
The correct answer is option D. "Industries need to work with grater intensity and produce more".
Step-by-step explanation:
One of the reasons why Stalin was able to defeat Hitler by the end of World War II was the implementation of the Third Five-Year Plan (1938-41) that helped to boost the economy of the Soviet Union. Part of the plan was to shift resources to other sectors to embrace industrial production, Stalin expected a quadrupling of outputs of heavy industry, which had good results because by 1939, only the U.S. and Germany had higher industrial output than Soviet Union. However, this focus on industrial production had negative effects in other areas such as agriculture.
