Answer:
The notice was issued by the Imperial Germany Embassy to ask the tourers and the trippers to change their routes of voyage.
Step-by-step explanation:
- After the outbreak of World War I, the waters adjoining Great Britain were no longer safe for travelling.
- This notice was issued following the incident of the sinking of a ship named Lusitania by a submarine there.
- Keeping in view the safety of their citizens and other civilians, the Imperial Germany Embassy issued a notice that served more like a warning asking the travellers to stop using the waters neighboring Great Britain.
