Discussion Forum : Logical Deduction - Section 1 (Q.No. 21)
Directions to Solve
In each question below are given two statements followed by two conclusions numbered I and II. You have to take the given two statements to be true even if they seem to be at variance from commonly known facts. Read the conclusion and then decide which of the given conclusions logically follows from the two given statements, disregarding commonly known facts.
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: All poles are guns. Some boats are not poles.
Conclusions:
- All guns are boats.
- Some boats are not guns.
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.

Some boats are not poles but they can be guns. All poles are gun.

Conclusion II follows.
Some boats are not guns. So the answer should be B.
Some boats are not guns. So the answer should be B.

Syllogism, rule no 2:
No term can be distributed in the conclusion unless it is distributed in the premises.
No term can be distributed in the conclusion unless it is distributed in the premises.

It is stated that "All poles are guns. Some boats are not poles".
It can be also deduced that, some boats are poles and every poles is a gun. This implies that some boats are guns, thus also some boats are not guns. So the second conclusion follows. So I'll go with B.

Correct answer should be B! No doubt.
If "All guns are boats. " changes to "Some boats are guns" (they are not equal logically!) , then D is correct!
If "All guns are boats. " changes to "Some boats are guns" (they are not equal logically!) , then D is correct!

As it is already mentioned that some boats are not poles and all the poles are guns, so on creating a venn-diagram of it, the portion acquired by the poles in the guns cannot be fully occupied by the boats.

1. Guns is the super set of poles.
2. Set{boats}! = set{poles} and neither boats can be the super set of poles, nor poles can be superset of boats.
From 1 & 2 its clear that boats cannot be the superset of guns, so conclusion I will not follow.
It is possible that some boats are not guns but it is also possible that all the boats are guns, as its not clear conclusion II will not follow.

I agree with supporters of Option B. The implication from statement II is that some boats are poles. Therefore some boats are guns.

Poles = Guns.
Some Boats are Not Poles.
Hence,
Some boats are Not guns. (Using equation 1).
Where is the fault then. Only conclusion II follows.
According to me.
Some Boats are Not Poles.
Hence,
Some boats are Not guns. (Using equation 1).
Where is the fault then. Only conclusion II follows.
According to me.
