Fully disjunctive reasoning

Here a easy question for you – Jefferson is looking at Teresa, but Teresa is looking at George. Jefferson is married, but George is not. Is a married person looking at an unmarried person?

  • B) No
  • C) Cannot be determined

…and more…

…moar I said!

You are close…

…just a little more…

…OK – just one last scroll.

You choose C, cannot be determined answer, right? So you are wrong!

The right answer is A. “What the heck?”, you may say. But let see how the situation looks like. We know, that Jefferson is married, but George is not. We don’t know if Teresa is married. But if she is married, then she would be looking at unmarried person – so answer A. If she is not married, then Jefferson is looking at her – so answer A. Tricky, uh?
