Logical Reasoning - Statement and Conclusion - Discussion

Discussion Forum : Statement and Conclusion - Section 3 (Q.No. 34)
Directions to Solve

In each question below is given a statement followed by two conclusions numbered I and II. You have to assume everything in the statement to be true, then consider the two conclusions together and decide which of them logically follows beyond a reasonable doubt from the information given in the statement.

Give answer:

  • (A) If only conclusion I follows
  • (B) If only conclusion II follows
  • (C) If either I or II follows
  • (D) If neither I nor II follows and
  • (E) If both I and II follow.


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.


  1. Americans have not been able to develop enzymes.
  2. Animal by-products protein has the same composition as soya protein.
Only conclusion I follows
Only conclusion II follows
Either I or II follows
Neither I nor II follows
Both I and II follow
Answer: Option
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.

The Same enzyme is being used. So the protein must also same.

There is no need for reinventing the wheel. @Soham.

If Americans could develop their own enzymes. Why would they use one made by Japan?

Enzymes are substrate specific, hence composition should be same.

I agree with dipinn and my answer was choosing choice A.

Dipinn said:   1 decade ago
As Same enzyme is used to break down the Soya and Animal Protien, this may be because of the similar composition.
