Question: On the page "Logical connective",  in the first five examples under "Introduction", the 2nd and 3rd examples are as follows:

2. If it is raining, then I am inside;  in symbols,  P implies Q

3. It is raining if I am inside     ;   in symbols,  Q implies P

Yet example 2 is labeled "material consequent",

and example 3 is labeled "biconditional (xnor)".

Is example 3 labeled correctly? It looks like a "material consequent" in symbols. Christian424 (talk) 04:27, 21 March 2008 (UTC)
