13. You have 3 boxes, one red, one blue, and one green.  Inside each box is one marble which is the same color as the box.  Someone takes each ball out and puts in a different colored box.  You open only the red box and pull out a green marble.  What color is the marble in the blue box?  Red  Frank Green, Anita Dixon.

BONUS 1:  (This puzzle was used last fall as NPR’s Puzzle Challenge on their “Sunday Puzzle” portion of the Weekend Edition program.  I found it while reading an article about one of the over 2000 folks who solved it.)  Think of a popular tourist attraction with two words.  The second, fourth, and sixth letters of the second word, in order, spell the first name of a famous author.  The last four letters of the first word spell the author’s last name.  Who is the author, and what is the tourist attraction?  Ayn Rand.  Grand Canyon  Frank Green, Alexis Avis, Anita Dixon.

Bonus 3:  Take any prime number greater than 3, square it and subtract 1.  What is the largest number that must be a factor of the result.  24.  (this is a surprising result, with a beautiful and elegant ‘proof’.  Holler if you’d like to see it.) Anita Dixon.
Bonus 4:  See #6 above. The multiple choices there don’t seem to account for a male speaker.  But isn’t it possible?  What would the answer be if so?  (Let’s assume all relationships are biological [no step/half siblings, parents, etc.]  Son-in-law. Anita Dixon.
