9、e that supplies could be stopped by wars or shipping trouble.For many years people tried to make something to take its place, but they could not do it. In the end, they found a way of making artificial, man-made rubber which is in many ways better than and in some ways not as good as natural rubber.

10、 For many years, attempts were made to produce a substitute, but they were unsuccessful. Finally, a method was discovered of producing synthetic rubber which is in many ways superior and in some ways inferior to natural rubber. They make artificial, man-made rubber in f a c t o r i e s b y a complic
