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:
1. Americans have not been able to develop enzymes.
2. Animal by-products protein has the same composition as soya protein.
Answer: D
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.
