On-air challenge: Sunday is Veterans Day, so we have a game of categories based on flags. Given some categories, for each one name something in the category beginning with each of the letters F, L, A, G and S.
For example, if the category were chemical elements, you might say fluorine, lead, argon, gold and sulfur.
Last week's challenge from longtime listener Merl Reagle: The words "organic" and "natural" are both commonly seen at health food stores. What other seven-letter word, also commonly seen at health food stores, has five letters in common with organic and five letters in common with natural?
Winner: Mike Sublett, Portland, Ore.
Next week's challenge: With one stroke of a pencil you can change a capital F into E; you can change an O into a Q, and so on. Write the phrase "LEAD PENCIL" in capital letters. Add a stroke to one letter and rearrange the result to name a classic movie. What is it?
If you know the answer to next week's challenge, submit it here. Listeners who submit correct answers win a chance to play the on-air puzzle. Important: Include a phone number where we can reach you Thursday at 3 p.m. ET.
