Only one person knows. Per riddle.
The blind man and the riddler.
I can't wait any longer! I give bigheadfred full credit for being the only one even to attempt to answer one, or both riddles. Over 100 visits to this new Lesson and almost everyone passes on BOTH questions for the obvious reason that nobody has a clue.
Solution to Prisoner RiddleFirst prisoner looks at the other two and does NOT see two red hats. Therefore he could have red or black and he answers "I don't know."
Second prisoner looks just at third prisoner to see if HIS is red. If so, second prisoner knows his own is black BECAUSE prisoner one did NOT see two red. Since he does NOT see red, he says "I don't know."
Third prisoner is very smart and reasons that his must be black, so he says "I'm wearing black. Buh bye!"
Solution to English Riddle"Kits, cats, sacks, wives, how many (of those!) are going to St Ives?" --Zero. None.

Lesson Within That LessonThe same is obviously true when discussing politics, science, or anything else.
Facts are secondary to how those facts are interpreted. The Left invariably descends into "You're stupid and anti-science" and so the Right, frustrated by being called stupid and anti-science*, resorts to name-calling as well.
Evolution or climate change discussion, anyone?
