Answer: The reader can make the inference that Great Britain was the starter of the war with Germany.
Explanation: The excerpt narrates how was the first offensive action of the war on behalf of Great Britain. It tells how they saw the transatlantic cables that went from Berlin to the United States as an opportunity to know classified information, and how they deliberately made Germany know that war was on its way. The reader can infer then, that Great Britain was the one who formally started everything.
