What if were set some problem where we are told to assume that

2+2 = 5
1+1 = 2
1+1+1+1+1 = 5

3rd one looks fine to me. :)

Edit: Whoosh. Yes, that was the sound of this going right over my head.

I'm surprised you don't like the 2nd one :)

The point being one false statement declared as true is enough to render logical derivations unrelliable no matter how many true statements you include with it.
