Where It's At

On-Air Challenge: Every answer is a familiar two-word phrase with AT in the middle. The letter A ends the first word of the phrase, and the letter T begins the second word. For the clue, "trying out of something while changes are still being made," the answer would be "beta test."

Last Week's Challenge: Think of a familiar three-word phrase in the form "___ and ___". If you remove the "and" and put the second word in front of the first word, you get a compound word naming a place of power. Hint: The compound word has nine letters. What is the three-word phrase, and what place of power is this?

Answer: Room and board, boardroom

Winner: Mike Stahl, Byron, Ill.

Next Week's Challenge: From listener Dave Taub of Eugene, Ore.: Take the name of a well-known U.S. university. One of the letters in it is a chemical symbol. Change this to a two-letter chemical symbol to name another well-known U.S. university. What universities are these?
