On-Air Challenge

To mark Liane Hansen's 20th anniversary hosting Weekend Edition Sunday, this puzzle is a game of categories using the word "radio." Will names the categories, and the guest names something in the categories beginning with each of the letters in "radio." For example, if the category were women's names, the answers might be Rachel, Alice, Doris, Imogen and Opal.

Last Week's Challenge

From listener Ed Pegg Jr., who runs MathPuzzle.com:

Take the name "Noah Adams," as in the former host of All Things Considered. Add the phrase "false teeth." You can rearrange all 19 letters to name a famous work of literature. What is it?

ANSWER: Will's intended answer was "The Death of a Salesman," though he admits a flaw — the actual name of the work does not start with the word "The."

WINNER: Dave Taylor of Glendale, Calif.

Next Week's Challenge

If you write "WOW" in capital letters and hold up a mirror at the side of the word, you'll see "WOW" perfectly reflected in the mirror. Here's the puzzle: Think of a nationality and write it in capital letters. If you remove one stroke from the first letter, and one stroke from the last letter, and hold up a mirror at the side, the name of the nationality will be perfectly reflected in the mirror. What nationality is it?
