NPR Sunday Puzzle (Aug 11, 2013): Twisted Family Tree:
Q: It's a twist on an old puzzle: Nieces and nephews have I none, but that man's father is my father's son." What is the gender of the speaker? And who is the speaker referring to?
Honestly I don't see the reason, except for the slight wording change at the beginning, that this is any different than the classic puzzle. Am I missing something? Was it perhaps stated differently on the air?
Edit My hint was the word "reaSON". Again, I don't see why this puzzle is much different from the classic puzzle. Working backwards, my father's son is either the speaker himself or the speaker's brother. If that person was "that man's father" it would either be the speaker's son or speaker's nephew. In the classic puzzle this second case was eliminated because the speaker has no brothers. In the revised version, it is still eliminated because he has no nephews. But in either case, the answer is the same.
A: The speaker is male and he is talking about his son.
