Final answer:
Thomas Hardy's poem "Channel Firing" predicts World War I, which was a major event that created a significant divide between Western Europe/America and the rest of the world due to its devastating impact on social structures, political ideologies, and global power distributions.
Step-by-step explanation:
The poem "Channel Firing" by Thomas Hardy predicts World War I. Written in the years preceding World War I, Hardy illustrated the turmoil and impending chaos that would erupt across Europe and lead to the first mechanized global conflict. The Industrial Revolution, with the stockpiling of modern weapons and competitive economic measures such as tariffs and taxes, as well as changing power dynamics among nations, all contributed to a tense atmosphere that eventually triggered the war.
World War I caused a profound divide between Western Europe/America and the rest of the world. The conflict led to the destruction of old social structures, the emergence of nationalism and revolutions in various countries, and set the stage for drastic political ideologies like Nazism and fascism. It was such a significant event that it directly influenced the geopolitical landscape, class structures, race relations, and economic stability, leading to World War II.
Thus, the event that created a significant divide between Western Europe/America and the rest of the world was World War I (D from the multiple-choice options).
