Think logically. Do you dare to challenge it?
There were three hunters, one black bear and two brown bears. They now have to cross the river, but now there is only one boat. The boat can carry two people or one person and one bear or two bears. There are hunters and trained black bears who know how to punt. If the number of bears exceeds the number of people, the bears will harm people. How can I cross the river safely?
