  a. ALL Pure is Sure
b. Some Pure are impure

from above 2 statements which of the below follow:-
i) All Sure are impure
ii) Some sure are impure
iii) Some sure are not impure

I think (iii) should also follow . Please comment on this one.

  It can be the case that sets for Impure and Sure overlap perfectly, which is why I think 3 cannot follow.

  As per the range of the word SOME is considered,it goes from 0 to the maximum amount ,so if some is put as ALL in the 3rd option,it would mean that no SURE is IMPURE,which is certainly false because atleast 1 SURE is IMPURE.
