Question

Statement: About 50% of animal by products, hair, skin, horn etc. is edible protein. Indian chemists have developed a method of isolating 45% of this protein. They used an enzyme developed in Japan to break down soya protein.
Conclusions:
I. Indian have not been able to develop enzymes.
II. If an economically feasible process is developed there would be plenty of edible protein available.

A. Only conclusion II follows

B. Both conclusions I and II follow

C. Only conclusion I follows

D. Neither conclusion I nor II follows

Answer: Option D

Solution (By JKSSB Mock Tests)

Conclusion I does not follow because using an enzyme developed in Japan does not imply Indians cannot develop enzymes. Conclusion II is not directly supported; the statement only mentions isolation of protein, not about economic feasibility leading to plenty of protein.

Correct Answer: Option B

Explanation:
Since some cups are plates, and no plates are spoons, the portion of cups that are plates can never be spoons. Thus, some cups are definitely not spoons (Conclusion I). However, we do not know about all cups, so we cannot definitively say no cup is a spoon (Conclusion II).
