Final answer:
The year of visiting a Titanic exhibit varies as it depends on the individual's personal experience. The Titanic itself sank in 1912, while the Lusitania, another British passenger ship, was sunk by a German U-boat in 1915, contributing to WWI tensions.
Step-by-step explanation:
The question posed seems to refer to a personal experience of visiting the Titanic exhibit, which does not provide a specific historical year that can be generalized for everyone. With no universal date for when 'we' visited the Titanic exhibit, the specific year for the student's visit cannot be determined. However, if we interpret 'Titanic exhibit' in a historical sense, the Titanic itself was a British passenger ship that was the largest of its time and famously sank on April 15, 1912, after hitting an iceberg. Exhibits about the Titanic have been set up at various times and locations since then, continuously providing insight into this historic event.
The information provided regarding the sinking of the Lusitania pertains to another historical maritime disaster. The Lusitania was sunk by a German U-boat on May 7, 1915, which contributed to the American public's outrage and influenced the United States' stance during World War I. The Smithsonian interactive exhibit mentioned addresses the wider context of World War I, which provides a broader historical backdrop against which both the Titanic and Lusitania events occurred.
