Logic puzzle

You've just spent the day at the market. You are heading home with a wolf, a goat, and a cabbage in tow, when you encounter a river with a small boat. Of the wolf, the goat, and the cabbage, one will always tell the truth, one will always tell lies, and one will not speak. What question do you ask?

I ask the goat what the wolf would say about whether or not the cabbage can speak, and then bring the one that only tells the truth and turn the other two into a hot dinner.
