Final answer:
British naval expenses in 1914 were high, confirming the German concerns regarding freedom of the seas. With the British Navy's overwhelming superiority and strategic efforts like blockades and the U-boat war zone declarations, Germany sought to counter British dominance through its submarine fleet.
Step-by-step explanation:
In 1914, the British naval expenses were substantial, reflecting the nation's commitment to maintaining naval supremacy. The British Navy was more than double the size of its closest rival, which fueled German concerns regarding freedom of the seas.
Germany's approach to counter British naval dominance relied heavily on its submarine fleet, as surface ship confrontations were unlikely to end in its favor. Despite Germany's efforts, including employing submarines in declared war zones around Britain, the British blockade significantly hampered German imports, causing shortages.
