Lake Crossing II
Learners complete the following problem by using logic: Three couples, the Smiths, the Jones and the Browns wanted to go to the Brown's yacht that was moored a little way out in the lake. There was a dinghy to take them to the yacht but it only held two people at a time. What's more, each of the wives was jealous of their husbands and wouldn't let him be with any of the other wives unless she was there. Can they all get successfully to the yacht?
