I want to know the answer to the following question:
What is one example of traffic that passed through Hanover?
All the background I'm provided with is that "It was connected to the Hanseatic League city of Bremen by the Leine, and was situated near the southern edge of the wide North German Plain and north-west of the Harz mountains, so that east-west traffic such as mule trains passed through it.". Is that enough to answer the question?
Answer: yes
