Question

What happened in Europe as a result of the Industrial Revolution?

Europe saw a decrease in nationalism and a greater sense of cooperation among nations.
European nations focused more on internal improvements and avoided the expansionism that they saw in America.
European nations grew more isolationist in order to protect their trade secrets.
Some European countries grew into major industrial powers and began taking over territory outside of Europe.

Answer 1

The correct answer is:
"Some European countries grew into major industrial powers and began taking over territory outside of Europe."

Brief explanation: Industrialization gave certain countries greater economic and military strength, a demand for raw materials and new markets, and new technologies (steam power, railways, modern weapons). That accelerated imperialism — e.g., the British, French, Germans, Belgians, Dutch, and others expanded their overseas empires (the Scramble for Africa, increased control in Asia). The other choices are incorrect: nationalism and competition generally increased rather than decreased; European states did not avoid expansionism or become broadly isolationist in order to protect industrial secrets.
