If the statement 'No lions are herbivorous animals' is given as true, which of the following statements can be immediately inferred to be false?

1.All lions are herbivorous animals

2.Some lions are herbivorous animals

3.Some lions are not herbivorous animals

A2 only

B1 & 2 only ✓ Correct

C1 & 3 only

D3 only

Correct answer: (B) 1 & 2 only

Explanation

Statements 1 and 2 can be inferred false.

The given "No lions are herbivorous animals" is an E proposition, taken true.

Its contrary, the A "All lions are herbivorous animals" (1), must then be false.

Its contradictory, the I "Some lions are herbivorous animals" (2), is also false.

Statement 3, the O, stays true by subalternation, so only 1 and 2 fail.
