Assess students' understanding of the Marshall Plan (European Recovery Program) by testing knowledge of its objectives, design and implementation mechanisms (aid allocation, conditionality, role of OEEC and U.S. agencies), political aims, and measurable short-term economic impacts on Western European countries from 1948–1952 — including GDP and industrial output growth, trade and balance-of-payments effects, monetary stabilization, and cross-country differences; require explanation of causal links, evaluation of evidence, and acknowledgment of limitations and alternate explanations.
