One day, Nick invited his friends to supper. He was cooking some delicious food in the kitchen. Suddenly, he 1        (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 2         too little.

 His son looked surprised. “I can understand why I shouldn’t pay too much, Father, but if I can pay less, 3         not save a bit of money?”
