請依下文回答第 41 題至第 45 題：    The Titanic, designed as the largest ship ever to go to sea, was one of the White Star Line's vessels thatcatered to the most elite passengers. It took three years to build the Titanic and in the end the ship cost $7.5million dollars. More than 3000 men were employed in building the Titanic. In the months, and even years,leading up to the maiden voyage of the ship; the White Star Line published numerous marketing materialsclaiming that the Titanic was designed to be "unsinkable."  The construction methods used in the building of the Titanic were considered to be second to none. Sixteencompartments were said to be watertight. Builders of the Titanic had included steel doors that were supposed tohave been capable of shutting in 25 seconds or less, thereby enclosing any water that might have seeped in tothreaten the safety of the ship and her occupants.   Of course, we now know from photographs taken of the ship's wreckage, that in all likelihood many of thenearly three million rivets that were employed to hold the ship's hull plates together popped loose when the vesselstruck a massive iceberg. Without the rivets to hold the plating together, they quickly buckled, allowing water toenter the ship. New theories have suggested that the iron used in the Titanic's construction may not have been thebest quality, containing high degrees of sulfur, which made the hull plates particularly susceptible to the icy coldwaters of the North Atlantic. Builders of the Titanic can hardly be blamed for the iron's contribution to the tragicsinking, however. The iron used in the construction of the Titanic was standard for the first part of the 20thcentury. While the high sulfur content in the iron may have played a role in the tragic history of the Titanic, it wasnot the sole reason the ship sank.    Reports from surviving crew members indicate that the ship had been ordered to proceed through the watersof the North Atlantic faster than safety permitted. Numerous other vessels had reported the presence of several iceflows in the area on the day the ship sank, yet the Titanic made no effort to slow down. When it became obviousthat the ship was about to collide with a huge iceberg, crew members attempted to turn the ship, hoping to avoidthe berg all together. They were unsuccessful, however, and the ship sustained numerous gashes along the hull.Some theories speculate that had the ship hit the iceberg head-on, the damage would not have been nearly sotraumatic and the Titanic and her passengers would have been able to complete their journey.
