Final answer:
Steerage passengers, often immigrants, were located on the lowest level of the Titanic, enduring unsanitary and cramped conditions unlike the luxurious settings of the upper classes.
Step-by-step explanation:
The individuals who were located on the lowest level of the Titanic were primarily the third-class passengers, commonly referred to as steerage passengers. These passengers, who were often immigrants, traveled in the most basic accommodations. They experienced cramped and unsanitary conditions, far removed from the opulence enjoyed by first-class travelers. The third-class passengers had limited access to amenities and shared common areas, which also served as sleeping quarters. This was a stark contrast to the privileges of the wealthier passengers on the upper decks who had access to luxurious staterooms and extravagant dining salons. The Titanic was the largest passenger ship built at that time, and the tragedy of its sinking highlighted the stark differences in class and comfort provided to travelers on such transatlantic voyages.
