One question with a A,B,C,D choice answer.
The question was like "After Uraninium breaks down, what is the last result element?"
A: Iron
B: Platinum
C: Copper
D: Lead
The contestant went through a process of elimination by saying Iron and copper is abundant, Platinum is very rare, and Lead is the one element that can shield against Radiation.
$50,000 won for that. How long does it take for uranium to decay to lead?
