Statements: All poles are guns. Some boats are not poles.

Conclusions:

  1. All guns are boats.
  2. Some boats are not guns.
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
Explanation:
Clearly, the term 'guns' is distributed in both the conclusions without being distributed in any of the premises. So, neither conclusion follows.

It's a rule when all and some not comes with same subject and predicate then it becomes either or case.

I think the answer must be C because in conclusion, one conclusion is positive and the other is negative. Both conclusions are wrong also after checking. Elements are also same in both conclusions. It proves all the 3 conditions of either case are true here. So the answer is c.
