Test analysis: This question is relatively simple. Cartoons reflect that the Soviet national economy gave priority to the development of heavy industry in the 1930s, ignoring agriculture and light industry, which led to the imbalance of the national economy. Therefore, it is wrong to choose item A. The military industry was not far ahead in the 1930s. C mistake, Stalin system gives priority to the development of heavy industry, and people's living standards lag behind; Wrong D, the national economy is unbalanced and the economy cannot develop healthily.

Comments: Stalin system is a highly centralized political and economic system established in 1936. This system unilaterally developed heavy industry, neglected the development of agriculture and light industry, seriously unbalanced the proportion of the national economy, ignored the relationship between goods and money, and relied solely on the administrative instructions of the state, becoming more and more rigid, which eventually led to the disintegration of the Soviet Union. But the positive aspects of this system also need to be mastered.
