Conundrum: Venn in Doubt
Tuesday, April 3rd, 2007In a Venn Diagram puzzle, there are three overlapping circles, marked A, B, and C. Each circle has a different rule about who or what can go inside. The challenge is to guess the rule for each circle. You can find a more detailed explanation of Venn Diagram puzzles, along with an example, here.
This week, we’re going to try a twist on the increasingly-classic Venn Diagram puzzle. The entry for the center section has been removed. Can you still guess the rules without the most important clue?
Have you figured out one of the rules? Two? All three? Feel free to post whatever you’ve got in the comments below. Just tell us which circle you’re solving, and what the rule is.
And, for an extra challenge, can you figure out what should replace the question mark in the center?
Enjoy!
UPDATE: Circles A, B, and C solved by Annalisa. The center clue has been solved by Kenneth W. Davis. Alternate answer for the center suggested by Brian. See comments for answers.
