A farmer once organized a competition between his dog and his rabbit. He dug a hole in one of his biggest fields, and hid a carrot and a bone in it. He wanted to see      animal would find them first.
The       (cheer) and optimistic rabbit threw himself into looking for the carrot,        (lie) down and began to complain about how difficult it was to find one bone in such a big field.
The rabbit dug    hours, and with every new hole the dog complained even more about how difficult this was, even for the rabbit.     the rabbit thought that each hole dug was one hole less that needed to be dug. When there was no place in the whole field       (leave) to dig, the rabbit dug a tunnel right to      the dog had been lying all the time. There he found the carrot and the bone.
This is how the dog lost the game. He had come to       right place at the very beginning but failed to find the bone       he only complained and didn't try at all.
