The treaty above is most clearly an example of which of the following?

(A) A reduction of barriers to trade across international borders (B) A secret treaty to maintain the balance of power in Europe (C) Reconstruction efforts to rebuild Europe after World War II (D) A response to aggression from outside of Western EuropeExplanation: The North Atlantic Treaty is the document responsible for the creation of NATO, the U.S.- centered alliance bloc in the Cold War. Eliminate (A) because NATO is focused on defense, not trade. Eliminate (B) because secret treaties occurred during World War I, not the Cold War. Eliminate (C), as it invokes the Marshall Plan, which was economic aid to Europe, not military defense as stated in the document.
