Question

The second statement is the _________ of the first?
[ A to B]
[-A to -B]

A.Contrapositive

B.Inverse

C. Contradion

D.Converse

Answer 1

Well, if
[A to B]
is the statement
its contrapositive is
[-B to -A]
its converse is
[B to A]
its contradiction, if I'm not mistaken, is
[A to -B]

That leaves just one of the choices :)

Answer 2

Inverse, but why not contradiction?

Answer 3

Contradiction doesn't negate the first (antecedent)
Notice that the contradiction is
[A to -B]
and the Inverse is
[-A to -B]

These are two very different statements :)

Answer 4

Ah! Splendid sounds legit, thank you very much. ;)

Answer 5

Anytime :)
