Explanation:

To determine the major event, we analyze the causes: Intellectual curiosity, desire for wealth, European demand for Eastern goods, and the Ottoman Turks shutting down the Silk Road (blocking traditional trade routes) all align with the motivations for European Exploration. World War I was about alliances and conflict, The Crusades were religious wars, and The Industrial Revolution was about manufacturing innovation—none match these causes as well as European Exploration.

Answer:

European Exploration
