Last week's challenge: This week's challenge comes from Joseph Young, of St. Cloud, Minn., who conducts the blog "Puzzleria!" It's a little tricky. When you remove the last letter from Germany, Sweden, or Somalia, what remains is a native of that country. What country, if you remove its last letter, also leaves a native — but only after you rearrange its remaining letters?
Challenger answer: Vietnam (native)
Winner: Steven Bailey of San Francisco
