I always find it easier to replace these statements with just variables

1) $\displaystyle a\Rightarrow b$ baby implies illogical

3)$\displaystyle b\Rightarrow c $ illogical implies despised.

2)$\displaystyle d \Rightarrow \sim c$ can manage a croc implies not despised

For 2 I find it easier to work with the contrapositive,

which would be $\displaystyle c \Rightarrow \sim d$ despised implies cannot handle a croc.

now I think you can string these together to reach a conclusion that the statement cannot be true. - Aug 16th 2009, 02:44 PMPlato
