Where you are asked to explain or defend your answer, short answers are fine. Five hobbits and five orcs must cross a river. There is a rowboat that will hold three creatures. The orcs may never outnumber the hobbits on either side of the river or in the boat. Of course, the boat must always be powered by one of the creatures and those creatures in the boat count as if they were on the corresponding side of the river.
