I want to know the answer to the following question:
The small North German navy had how many ironclads at their disposal?
All the background I'm provided with is that "When the war began, the French government ordered a blockade of the North German coasts, which the small North German navy (Norddeutsche Bundesmarine) with only five ironclads could do little to oppose.". Is that enough to answer the question?
Answer: yes
