Which area was NOT one of contention between the Triple Alliance and the Triple Entente?

North Atlantic

Eastern Europe

Africa

Central Europe

My best answer would be:

C.) Africa

The North Atlantic saw unrestricted sub warfare along with Naval battles, such as The Battle of Jutland.

Eastern Europe was where a huge chunk of the fighting in World War 1 was, it was called "The Eastern Front"

Central Europe saw fighting aswell.

Africa didn't have as much fighting in the First World War, such it's probably the correct answer.
