The Congress of Vienna in 1815:

A. was attended by representatives of France, Britain, Italy and the United States.
B. operated in accord with the principles of liberalism.
C. agreed to meet periodically to take steps to maintain Europe’s peace and stability.

C

The correct answer is C. The Congress of Vienna in 1815 agreed to meet periodically to take steps to maintain Europe's peace and stability.

To arrive at this answer, you can use a few different methods:

1. Historical knowledge: If you have a good understanding of European history, you may already know that the Congress of Vienna was a gathering of major European powers after the defeat of Napoleon to discuss and decide on the future of Europe. One of their main goals was to establish mechanisms for maintaining peace and stability in the region.

2. Process of elimination: By eliminating the incorrect options, you can determine the correct answer. Option A is incorrect because the United States did not attend the Congress of Vienna. Option B is incorrect because the principles of liberalism were not the driving force behind the decisions made at the Congress. Option D is also incorrect, as it describes the Concert of Europe, which was a separate cultural initiative.

3. Research: If you are unsure or unfamiliar with the Congress of Vienna, you can conduct some research to gather information. A quick internet search will provide historical sources and references that explain the purpose and outcomes of the Congress of Vienna, including the agreement to meet periodically to ensure peace and stability in Europe.

Remember, having a good understanding of the subject matter, using the process of elimination, and conducting independent research can all be helpful in arriving at the correct answer to a question.
