What does it mean when states are described as having "risen steadily" since World War II?

The phrase "risen steadily" in the context of states since World War II often refers to the increase in the number of recognized independent states. Following the war, many countries emerged from colonial rule or were formed due to changes in political boundaries, leading to a significant rise in the count of independent sovereign states. This trend highlights the shift in international relations, where the post-war era saw the establishment of numerous new states as part of decolonization and self-determination movements. As a result, the global landscape has changed, with an increased number of actors participating in international relations. This growth in statehood reflects the evolving nature of sovereignty and global governance.

Other choices do not accurately capture the concept of "rising steadily" as it pertains to states. The diminishing power of existing states, decreasing influence of superpowers, or compromised stability does not align with the notion of an increase in recognized independent entities on the world stage. Instead, these options suggest challenges or shifts in power dynamics rather than simple numerical growth.
