Answer 1

The best bibliogaphic entry would probably be: Smythe, Clark. Unsinkable: Folly on the Titanic 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.
