1. Statements: About 50 per cent of the animal by-products - hair, skin, horns etc. is edible protein. American chemists have developed a method of isolating 45 per cent of this protein. They used an enzyme developed in Japan to break down soya protein. Conclusions: Americans have not been able to develop enzymes. Animal by-products protein has the same composition as soya protein.

That the American chemists used an enzyme developed in Japan, does not mean that Americans have not been able to develop enzymes. So, I does not follow. Also, nothing about the compositions of animal by products protein and soya protein is mentioned in the statement. So, II also does not follow.
