Answer

Brief Explanations:

During World War I, German U - boats used unrestricted submarine warfare and sank passenger liners like the Lusitania. This had significant political and public - opinion impacts. The war did not end quickly due to submarines. Submarines were not used for poisoning water supplies, nor did their use directly lead to greater support for air attacks.
