Hi!
I have been working in the core curriculum for some time and there is something that I am not quite clear about conditional reasoning and its inferences.
What I do know is that IF A, THEN B contraposes(is that a word?) to IF NOT B THEN NOT A. I know this must be true.
But what about IF NOT B THEN A? Is this a cannot be true or a could be true? Does this statement negate the original statement?
Help!
I didn't like any of these answers. Skipped completely during timed and then got it wrong with BR. Still don't understand how D can be rejected.
Being picky with words would have gotten this question right. I'm not yet ready for that level.
I couldn't even explain how I could prevent this mistake in the future.
