You are a prisoner in a room with 2 doors and 2 $NEWC guards. One of the doors will guide you to freedom of your investment and profit's in $NEWC and behind the other is a hangman -- you don't know which is which.
One of the guards always tells the truth and the other always lies. You don't know which one is the truth-teller or the liar either.
You have to choose and open one of these $NEWC doors, but you can only ask a single question to one of the guards.
What do you ask so you can pick the door to profits and freedom of $NEWC?
$!$! SPOILER NEWC ALERT !$!$
If you asked the $NEWC truth-guard, the truth-guard would tell you that the liar-guard would point to the door that leads to death.
If you asked the $NEWC liar-guard, the liar-guard would tell you that the truth-guard would point to the door that leads to death.
Therefore, no matter who you ask, the guards tell you which door leads to death, and therefore you can pick the other door that lead you to $NEWC profits.
