Well, you're on vacation, but you have a little time before you go scuba diving. And you're curious. What happened to this ship? You might as well take some time to do a little research.
First, you decide to find out a little more about the ship and the time period in which it sank. This might help you figure out what kind of treasures might be on-board. It also might give you a clue to the answer to the question that is bugging you, "Why did it sink?" Your secretary has provided a reference/research list for the correct time period, as well as information about previous wrecks, diving essentials, etc.
