Which of the following was a result of Japan's decision to industrialize and adopt Western technologies?

Question:

It became an imperial power.

It invaded and conquered China.

It declared war on the United States.

It returned to its isolationist past.

Answer:

The answer is >>It became an imperial power.<<

The question is asking what was the RESULT not the reason. The Meiji restoration brought Japan into a period of rapid industrialization and westernization, by the early 1900's Japan had already built a large and powerful navy that defeated the Russians, and lead to Colonization of Korea, by the end of World War I Japan had a very large navy that was later restricted in the Washington Naval Treaty (laying the seed-work for World War II).

Japan's imperialist army was one of the reasons that started World War II, remember the Navy did not want any part of it, but the Army pushed for it. However issues of WWII came way after Japan was already an imperial power. We're talking about the periods of 1860-1930 Japan was already an imperial power.
