C. by opening more economies to trade

The end of the Cold War expanded globalization primarily by opening more economies to trade, which is option C. This was possible because the Cold War was characterized by political and economic rivalries between two major powers, the United States and the Soviet Union, along with their respective allies. When the Cold War ended in the late 1980s and early 1990s, it led to the dismantling of many trade barriers and the opening up of previously closed economies. With the reduction in political tensions, countries began to engage in greater international trade, resulting in the global spread of goods, services, technologies, and ideas. This expansion of global trade and interconnectedness further accelerated the process of globalization. The other options, reducing the human cost of international conflict, forging needed military alliances, and promoting political revolutions, were also significant developments during the end of the Cold War but not directly related to expanding globalization.
