No one knew from where the terrible animals 3(come) to the town or how they could 4(destroy), because none of the means that already 5(use) against the rats were of much help. The citizens went to the Mayor and said: "We 6(lose) all patience. If you 7( not take) radical steps you 8(not remain) our Mayor!"
After that the Mayor declared that he 9(give) a bag og gold to anyone who 10(free) the town from the rats.
One day a young man 11(appear) before the Mayor and said that he 12(hear) about their trouble and 13(be) ready to help if the Mayor 14(keep) his promise. "Of course," the Mayor exclaimed. "If you 15( make) the rats 16(disappear) the bag og gold 17(be) yours."
The young man took an old pipe from his pocket and began 18(play). Suddenly a strange noise 19(hear) all over the town.

The young man expected the Mayor 36(keep) his promise but the latter said: "You 37(not do) any work at all. My citizens never 38(forgive) me if i 39(pay) so much og their money just for music."
