The ancient Egyptians were probably the first people to try to 22 them with poison, and this method is still being used today. This says a great deal about how 23 this method has been. We have set innumerable 24 , from simple wires to 25 machines that drowned the rats in beer! We have tried to inflect them with 26 developed germs. We’ve 27 tried to raise super cats to kill them. However, we are still losing the 28 .

　　35 all these phyical qualities, we also have the 36 that rats are rather good at not getting caught. They seem to have an almost supernatural ability to 37 when food has been poisoned and a suspicious rat will starve 38 it eats poisoned food. They also seem to be able to 39 a trap with no real difficulty.

　　One thing looks certain, we had better find a way to 40 these small brown creatures soon, or it may be too late.
