A monkey is looking for food around. He saw a fruit tree covered with fruits on the rocks from the gap of a rock. So desperately drilled in the narrow gap in the rock. If the monkey is, the fruit of the rock is the profit of it is eager, what will the monkey do? It chooses that will succeed, and the body has been grinded by rocks. Because of tired and hunger, monkeys are thin. In this way, at day 3, it was very easy to drill past, and eat fruit. After all the fruits on the tree, the monkey is ready to continue to find food, then he discovered that because it is too full, it can't come out again. This poor monkey did not find a profit model, the ending must be very tragic. Because, when it is finally hungry, it is exhausted from the gap of the rock, it is even weak to find new food. In fact, it can choose such a profit model: After you have a hard drill, put the fruit first to the side of the rock, then drill out, look for the next fruit tree while eating; he can also call a small monkey drill Over the gap, send the fruit together to share. Obviously, looking for a profit model, the result will be a hetero.
