Read the following passage from Chapter 4 of The Life and Adventures of Robinson Crusoe, in which Crusoe describes how he removes items from the foundered ship: . . .[P]reparing the twelfth time to go on board, I found the wind began to rise. However, at low water, I went on board, and though I thought I had rummaged the cabin so effectually, as that nothing more could be found, yet I discovered a locker with drawers in it, in one of which I found two or three razors, and one pair of large scissors, with some ten or a dozen of good knives and forks; in another I found about thirty-six pounds value in money, some European coin, some Brazil, some pieces of eight, some gold, and some silver.

I smiled to myself at the sight of this money. "O drug!" said I aloud, "what art thou good for? Thou art not worth to me, no, not the taking off the ground; one of those knives is worth all this heap: I have no manner of use for thee; e'en remain where thou art, and go to the bottom, as a creature whose life is not worth saving."
In the passage, Crusoe compares money to a drug. Explain some ways in which money was like a drug to Crusoe before being shipwrecked. Then, analyze the tone of the passage, and explain how the comparison helps create that tone. Support your response with specific details from the passage.
