It's here. Finally here. For weeks you've waited, checking the mail every single day, to no avail - but today, your invitation has finally arrived. You eagerly tear open the envelope and read:
Congratulations, [insert username here]! You have been selected as a member of this year's Treasure Hunt 'Round the World! Or at least, you're a preliminary member -- of course, we have to weed out the doers from the dreamers, and that's what this first challenge is for. Please solve it, and write us back at [redacted] with the answer attached. Then and only then will you receive your true invitation to the games.
Yours truly,
Bailey M
Puzzlemaster for the Treasure Hunt 'Round the World
At last, you can begin the puzzling experience of a lifetime! Excitedly, you flip over the card and read:

We've given you the answer... but what's the question?
The story continues in the next part, Treasure hunt 'round the world! (clue 1)
This is no longer being treated as a semi-interactive puzzle. Rather, it will be a linked-puzzle treasure hunt, which each clue being its own puzzle.
