The button is gladly pressed! And once it is, the entire fountain shuts down and the central statue splits and folds out to reveal a terminal! It is a foot wide and looks like it can be removed from its holder. The screen shows a field of stars, but soon turns yellow with simple blue letters that read:

"To access this terminal, your choice is a simple one: A or B.

"Answer correctly, and you may proceed.

"Answer incorrectly, and you may not live long enough to regret it."

Then two buttons appear onscreen, one with a bright A on it and a B on the other, both of them waiting for a decision to be made.
