Q1: Statements: Some dogs are rats. All rats are trees. Some trees are not dogs.
Conclusions:
A
None follows
B
Only I follows
C
Only I and II follow
D
Only II and III follow
E
All follow
ANS:B - Only I follows Explanation: Some dogs are rats. All rats are trees. Since one premise is particular, the conclusion must be particular and should not contain the middle term. So, it follows that 'Some dogs are trees'. I is the converse of this conclusion and so it holds. All rats are trees. Some trees are not dogs. Since the middle term 'trees' is not distributed even once in the premises, no definite conclusion follows. |
