“…chlorine gas, which is extremely deadly…” You fucking dumbasses. It’s either “deadly” (kills you) or it’s not. There aren’t degrees of something killing you; it either kills you or it doesn’t. If it kills you, it’s deadly. If it could kill you but won’t necessarily, it’s potentially deadly. If it doesn’t kill you, it’s not deadly at all. Pay attention, class: YOU CAN’T SAY “EXTREMELY DEADLY” BECAUSE IT DOESN’T MAKE ANY FUCKING SENSE AT ALL!
