Hi Masada, thanks for the question!
Funny enough that you should ask about A, but A is discussing a contrapositive.
If there is a necessary condition established for something, then it always holds that without this necessary condition we cannot have that something.
It describes the following:
A -> B; B is necessary.
Without B, A cannot hold
NOT B -> NOT A
This is not an error. In fact, contrapositives are always valid from their original conditional statement.
I hope this helps. Please let me know if you have any other questions or would like me to elaborate further!
