Wow.. that's hard. The choice which animal will survive or not easy at all. I probably would try to take 10 different animals and also have to remember that they must be useful later. The chicken and cow should be chosen. I would like also to rescue wild animals like lions, tigers, monkeys and elephants. The hippopotamus is to dangerous animal to stay with on the one boat. The horses and camels could be a good choice to. The last two animals would be the dog and sheep.
