RUMOUR

Today i went to watched movie with friend,then we had lunch together. During the lunch, we been talked about our friends rumour, which is AH DE, the rumour is about AH DE had broke up with his girl friend that had been dating for more than 5 years. I was shocked and said:'' that is impossible because i called AH DE yesterday and he was in well condition and he intend to marry his girl friend in the end of this year. In this case, IF AH DE break up with his girlfriend(A), then AH DE is lovelorn now(B). AH DE didnt lovelorn now and he was in well condition(B1) therefore AH DE didnt break up with his girl friend(A1). From this case, i'm using modus tones(denying the consequent) part of common pattern of deductive reasoning. This arguement got 2 premises. The first premises is the conditional "if-then" statement, namely that A implies B. The second premises is that B1 is false. From these two premises, it can be logically that A1 must be false as well.
