its like there are 3 carnivores and 3 explorers and they are on the same side of a river. you have to get all 3 explorers on the other side of the river without any explorers dying. there is a boat on the river and 2 people (exp. and carn.) have to go on it at the same time. it can be two of either or both. but one of the people have to bring the boat back to get someone else. how is this done!!!!
