What is your answer?

Suppose that Barbara gives you an argument, but her conclusion is definitely false. We can conclude that

    { 1 } - one or more of her premises is false.
    { 2 } - her conclusion doesn't follow from her premises.
    { 3 } - one of the other of these things happened.
    { 4 } - none of the above.

3 is correct!

Suppose that Barbara gives you an argument, but her conclusion is definitely false. We can conclude that

    { 1 } - one or more of her premises is false.
    { 2 } - her conclusion doesn't follow from her premises.
    { 3 } - one of the other of these things happened.
    { 4 } - none of the above.

If her conclusion is false, then something is wrong with her argument.

Either one or more of her premises is false, or else her conclusion doesn't follow from her premises.
