Final answer:
The Titanic received several ice warnings from nearby ships, while the Lusitania was warned by the German Embassy about potential sinking due to war conditions. The Titanic's warnings were not adequately heeded, and the Lusitania was sunk without direct warning by a German submarine.
Step-by-step explanation:
The Titanic received multiple warnings about icebergs from nearby ships before its fateful collision. However, these warnings were not heeded with the urgency and seriousness they required. The captain and crew were aware of the potential dangers, as were the passengers, but confidence in the ship’s design and underestimation of the iceberg threat contributed to the tragedy. In the case of the RMS Lusitania, which was mentioned in the reference, the German Embassy issued a warning in April 1915, asserting that British ships could be sunk by the German Navy due to the state of war. Less than a month later, the Lusitania was indeed sunk by a German submarine, without any warning given immediately prior to the attack, leading to a heavy loss of life.
