(In reply to re: Tips to solve... Hit a Wall !!! by Syzygy)

I agree - no one could get 5 right answers. So, the answers to the first two questions could have been AC, BA, CB or CC, and the answers to the last three TFF, FTF, FFT or FFF.

Unless I get a brighter idea, checking these 16 (4x4) combinations would find the answer, with no special reasoning involved...
