  • Question
  • Statement : The byproducts obtained from animals such as hairs, skins, horns, etc. contain at least 45 per cent food protein. Indian scientists have developed methods to segregate 50 per cent of this protein. They have used an enzyme developed in Russia for destruction of soya-proteins. Conclusions: A. Indian scientists cannot develop enzymes. B. If a suitable method involving less cost is developed then many more food protein would be obtained.


  • Options
  • A. Only A follows
  • B. Only B follows
  • C. Neither A nor B follows
  • D. Both A & B follows

  • Correct Answer
  • Neither A nor B follows 

    Explanation

    There is no indication that Indian scientists are incapable of developing enzymes. There could be any number of reasons why Indian scientists used Russian enzymes.

    So conclusion A does not follow.

    In addition, cost is not discussed in the passage at all. There is no mention of a correlation between cost and extraction of proteins.

    Thus, conclusion B does not follow either.
