If the statement 'All women are honest' is given as true, which of the following propositions can be inferred from it?
1.'No woman is honest' is false
2.'Some women are honest' is true
3.'No woman is honest' is undetermined
4.'Some women are not honest' is false
A1, 2 & 4 only ✓ Correct
B2 & 4 only
C2, 3 & 4 only
D3 & 4 only
Correct answer: (A) 1, 2 & 4 only
Explanation
From a true A proposition its contrary is false, its subaltern true, and its contradictory false.
'All women are honest' true makes its contrary 'No woman is honest' false (Statement 1).
By subalternation 'Some women are honest' is true (Statement 2).
By contradiction 'Some women are not honest' is false (Statement 4).
Since 'No woman is honest' is determinately false, calling it undetermined is wrong.
