Yellow Flag (Solution)
by Derek Kisman, based on an idea by Amos Eshel
At each position 1-9 of these answers (ignoring spaces), a single letter is repeated across two answers (e.g. there are two words that start with S, two that have second letter E, etc). These letters additionally spell out SEMAPHORE. Forming a semaphore flag by the two positions the answers are in (orientation is provided by red being on the ‘north’ side), and reading in the order of SEMAPHORE spells out the answer, WONDERING.
