Which of the following was not a primary cause of World War I?

a. Rise of nationalism

b. Increasing sizes of national militaries

c. Increasing globalization of the economy

d. Rise of imperialism

The correct answer is Option C) Increasing globalization of the economy.

Increasingly globalization of the economy was not a primary cause of World War I.

However, other options are better fit the narrative and were far more likely to cause the first World War.

For example, rising nationalism in the Balkans and Eastern Europe, the increasing size of the military in European countries and the rise of Imperialism had all led to world where major European powers were at each other's throats.

Britain was the dominant super power but Germany and France were constantly challenging this position.

Growing imperialist ambitions and large battalions were constantly involved in skirmishes around the world

It was about time, that the conflict became a full blown war.

I think the correct answer from the choices listed above is option C. The idea of increasing globalization of the economy was not one of the primary causes of World War I. Four main causes of the First World War were militarism, alliances, imperialism and nationalism.
