If the statement Some pandas are herbivorous animals is given as true, then which of the following statements can be immediately inferred to be false?
ANo pandas are herbivorous animals ✓ Correct
BAll pandas are herbivorous animals
CSome pandas are not herbivorous animals
DAll herbivorous animals are pandas
Correct answer: (A) No pandas are herbivorous animals
Explanation
No pandas are herbivorous animals must be false when the I proposition is true.
Some pandas are herbivorous animals is the I statement taken as true.
The universal negative E is the contradictory of I on the square.
Contradictories cannot share a truth value, so a true I makes E false.
The A and O forms stay undetermined and cannot be judged false.
