jimthompson5910 (jim_thompson5910):
If the sun isn't shining, then you are sad
But you just said you are NOT sad
So if B was correct, then you would be sad

a?
jimthompson5910 (jim_thompson5910):
yes
jimthompson5910 (jim_thompson5910):
that's the only thing we can conclude
If the sun wasn't shining, then you would be sad. But you are not sad. So the sun must be shining (for you not to be sad)
