Which best explains why Great Britain, France, and Russia formed the Triple Entente? 

The correct answer is:
They feared the rising military power of Germany and sought to counter the power of the Triple Alliance.

The Triple Entente (from French entente [ɑ̃tɑ̃t] "friendship, understanding, agreement") refers to the understanding linking the Russian Empire, the French Third Republic, and the United Kingdom of Great Britain and Ireland after the signing of the Anglo-Russian Entente on 31 August 1907. The understanding between the three powers, supplemented by agreements with Japan and Portugal, was a powerful counterweight to the Triple Alliance of Germany, Austria-Hungary, and Italy.

The answer to this question would be:

They feared the rising military power of Germany and sought to counter the power of the Triple Alliance.

Hope this helps :)
