One day, Nick invited his friends to supper. He was cooking some delicious food in the kitchen. Suddenly, he ______ (find) that he had run out of salt. So Nick called to his son, “Go to the village and buy some salt, but pay a fair price for it: neither too much nor too little.”
His son looked surprised. “I can understand why I shouldn’t pay too much, Father, but if I can pay less, why  not save a bit of money?”
“That would be a very ______ (reason) thing to do in a big city, but it could destroy a small village like ours,” Nick said.
Nick’s guests, who had heard their conversation, asked why they should not buy salt more _______ (cheap) if they could. Nick replied, “The only reason a man would sell salt at a lower price would be because he was desperate for money. And anyone who took advantage of that situation would be showing a lack of respect for the sweat and struggle of the man who worked very hard to produce it.”
“But such a small thing couldn’t ____(possible) destroy a village.”
“In the beginning, there was only a  very small amount of unfairness in the world, but everyone added a little, always _____ (think) that it was only small and not very important, and look where we have ended up today.”
