Historical bodies formed after world wars: “World War II : United Nations :: World War I : ?” Choose the organization that emerged in the aftermath of World War I.

Introduction / Context:
Many verbal analogy items use historical pairings. The United Nations (UN) was established in 1945 after World War II to promote international cooperation and prevent future conflicts. A parallel, earlier body was formed after World War I to pursue similar aims in a different structure and time.

Given Data / Assumptions:

• UN was founded post–World War II (San Francisco Conference, 1945).
• We seek the post–World War I counterpart.
• Multiple treaties and institutions arose around that period.

Concept / Approach:
The intended mapping is “major global conflict : international organization created thereafter.” After World War I, the League of Nations was established (Covenant attached to the Treaty of Versailles, 1919) as the first global intergovernmental organization focused on collective security and diplomacy.

Step-by-Step Solution:
1) Identify the second world war’s outcome: United Nations.2) Identify the first world war’s outcome: League of Nations.3) Select the precise organizational name, not a treaty.

Verification / Alternative check:
The League of Nations began operations in 1920 and functioned until it was replaced by the UN after WWII, confirming the symmetry with the prompt’s structure.

Why Other Options Are Wrong:

• Treaty of Versailles: A treaty, not an organization.
• International Commission of Jurists: NGO founded later; not the war’s direct institutional outcome.
• International Court of Justice: Judicial organ of the UN, created post-WWII.
• Permanent Court of Arbitration: Predates WWI (1899); not the specific outcome referenced.

Common Pitfalls:
Confusing organizations with treaties or courts; the analogy specifically calls for an organizational parallel to the UN.

Final Answer:
League of Nations
