Final answer:
The listing underlined with red is remarkable for listing key principles of communism, as it includes influential works by Marx, Engels, Lenin, and Stalin, which form the core ideological tenets of Marxism-Leninism.
Step-by-step explanation:
The listing underlined with red is remarkable because it lists key principles of communism.
Specifically, it mentions the four pillars of communism illustrated on a banner, which includes works by Marx, Engels, Lenin, and Stalin, representing the immutable laws of Marxism-Leninism.
These figures and their associated texts signify the ideological foundation and authoritative doctrines that have shaped communist thought and practice.
The Soviet propaganda posters often depicted these figures and their contributions to reinforce the narrative and inspire adherence to communist ideals, especially during the Stalinist era when Stalin's image was consolidated amongst the pantheon of communist leaders.
