Question: 6

Statements :
I. All poles are guns.
II. Some boats are not poles.
Conclusions :
I. All guns are boats.
II. Some boats are not guns.

(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

Ans: D

Clearly, the term ‘guns’ is distributed in both the conclusions without being distributed in any of the premises. So, no conclusion follows.

Question: 7

Statements :
I. All locks are keys.
II. No key is a spoon.
Conclusions :
I. No lock is a spoon.
II. No spoon is a lock.

(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

Ans: A

Since one premise is negative, the conclusion must be negative. So, I follows. But the reverse is not necessarily true. So,II does not follow.

Question: 8

Statements :
I. Some sticks are bolts.
II. Kite is a stick.
Conclusions :
I. Some bolts are sticks.
II. Some kites are bolts.

(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

Ans: D

The middle term ‘sticks’ forming the subject is not distributed in the first premise which is an I type proposition. The middle term forming the predicate is not distributed in second premise as it is an A type proposition and distributes subject only.

Question: 9

Statements :
I. Some bottles are pencils.
II. Some pencils are glasses.
Conclusions :
I. No glass is bottle.
II. Some bottles are glasses.

(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

Ans: D

Since both the premises are particular, so no conclusion follows.

Question: 10

Statements :
I. All bags are cakes.
II. All lambs are cakes.
Conclusions :
I. Some lamps are bags.
II. All lamps are bags.

(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

Ans: D

Both the premises being A type propositions, the middle term ‘cakes’ forming the predicate is not distributed in any of them.
Since the middle term is not distributed even once in the premises, so no conclusion follows.
