The sentence that correctly integrates the quoted information is sentence 4 (C).
First, it is important to remember that you can not have a quote be the only thing in your sentence. In needs some sort of introduction or your own words at some point in the sentence. You also need to remember to quote the text. There are different ways to do this in MLA form, you can put the author and page number in parenthesis at the end of the sentence (see sentence 2) or you can include the author's name in the sentence and put the page number in parenthesis at the end (see sentence 4). Since sentence 4, is more than just a quote and includes correct citations, it correctly integrates the quoted information.
In the opening sentence of the story the author states that "you were always a gambler" and you, "took chances."

The text foreshadows more to describe the main character being on a wooden ship.
