Q: Here's an example: Take the letters I, L, R and T. Insert a trigram (three-letter group) twice into these letters to complete a familiar 10-letter word. If you add S, P and O, you would get the answer, 'spoilsport.'On a scale of 0 to 9, I give this week's puzzle a 3.
Now, take R F E and R. Insert a trigram twice somewhere in these letters to complete a familiar two-word phrase. What phrase is it?
Edit: 0 to 9 would be the set of *digits* where 3 is the *fourth* digit.
A: Insert ING twice --> R(ING) F(ING)ER
