Answer:
I know that i'm late but the answer that I got was:
Problems arose in the fourth and fifth five-year plans, after World War II, the emphasis was on reconstruction, and in 1945 Stalin promised that the Soviet Union would be the main industrial power in 1960. Stalin focused his agricultural production leadership through the agricultural collectivization project, which he believed would bring good social and economic results to the Soviet Union. The evidence is located on page 62 where it says “At the end of 1932 Stalin proudly announced that the five year plan had been completed a year ahead of schedule.” McCollum, on the other hand, focused on industrial growth, which distinguished his position from Stalin's position on economic development. However, in order to focus on industrial growth, McCollum established projects that would increase the production and quality of agricultural products. The other evidence is on page 63 where it says, “The five year plan had created one of the worst famines in human history right in the middle of the country’s most productive farmland.”
