Question

Which one of these nations was NOT a part of the Triple Alliance?

Answer 1

The Triple Alliance consisted of Austria-Hungary, Italy, and Germany.

That means that the correct answer is Great Britain, as that nation was not apart of the Triple Alliance. The Triple Alliance lasted from 1882 to 1915. It ended due to Italy entering World War I with the plan of hostility towards Austria-Hungary and Germany. 

Answer 2

The answer is GREAT BRITAIN because all of the others at some point were part of the TRIPLE ALLIANCE at some point except BRITAIN. Hope i helped.
