The best bibliogaphic entry would probably be: Smythe, Clark. <em>Unsinkable: Folly on the Titanic</em> Little, Brown: New York, 1976.
That is because it seems to be a book about the Titanic itself, whereas the other ones have to do with:
- topics which are less directly related to the subject-matter (the first entry is about maritime laws and the third one is about the animal and plant populations of the lands near the North Pole),
- personal, relative accounts of the events (like the fourth entry, which is an autobiography of a survivor and therefore describes the wreck through the character's own perspective) as opposed to more factual material.
You cant start off thinking about the money, The first six months or fewer you won't be getting much. Do something you truly love and want to do.If I were you I'd start off working at places like a dairy queen or pizza hut something like that you are most likely to make money like that. but if you truly want to start a business then I would suggest sitting down talking to an adult about what you want to do, Also it comes down to if you're selling something such as bracelets, slime, nail polish .....whatever your selling, Or if you are doing good like doing hair, Painting houses...etc I would suggest sitting down and having an in-depth conversation.
