It’s a slow day in the so. of Fr.


A farmer wants to ferry a (giant) cabbage, a goat, and a wolf across a river in a boat. The problem is that the boat is small: besides the farmer it can carry at most one of the cabbage, the goat, and the wolf. To make things worse, without the farmer's supervision the goat would chew on the cabbage, and the wolf would chew on the goat. What is the minimum number of river crossings the farmer must make to accomplish his goal without the possibility of damage to the cabbage or the goat? (This is not a trick question, so creative shortcuts, such as taping the animal's mouth, roping the cabbage to the goat's back, etc., are not to be considered.)
a) 5
b) 7
c) 9
d) 11
e) he cannot do it in any number of crossings




Note to FTSE:  I know you’ll get it before the end of sentence #2, but let’s make the other soupers stew for a while!
