I escaped from a Nazi concentration camp in WWII Germany. I spoke fluent German; and with the help of the French Underground, I had authentic German clothes and travel papers of the time. Before crossing into Switzerland, I was stopped by the German Police. In our conversation, the Police were informed that my name was F.R. Braun. I was going to Geneva. I was married, with six children, and had travelled two hundred and fifty miles on my journey to visit relatives in Switzerland. My papers were in perfect order. I was immediately arrested and returned to my P.O.W. camp. Where did I make my mistake(s)?
Answer
During WWII, the Germans used the metric system. I stated miles instead of kilometres. Although the French did not invent the metric system yet metrication began in France in the 1790s and spread during the following two centuries to encompass all but three countries.
