Three closed boxes have either white marbles, black marbles or both, and they are labeled white, black and both. However, you’re told that each of the labels are wrong. You may reach into one of the boxes and pull out only one marble. Which box should you remove a marble from to determine the contents of all three boxes?
The one labeled both. Since you know it’s labeled incorrectly, it must have all black marbles or all white marbles. After you determine what it contains, you can identify the other two boxes by the process of elimination.
Stars awash in a sheen of light
It calls out loud in vile delight.
Listeners endure in fright.
Vicious brute that reigns at night,
Evil whelped of heinous bite,
Renewed by wax, it regains might.
A leading way to slay the beast,
Get the hidden weapon thus released.
What is this describing?
