question: furniture:wood
choices.label: A B C D
choices.text: drugs:tobacco gun:metal gene:cell gunpowder:chemistry
explanation: "wood" is the raw material for making "furniture". the raw material of "drugs" is not "tobacco", and there is no obvious logical relationship between "drugs" and "tobacco". "metal" is the raw material from which "guns" are made. "gene" is a component of a "cell", and the "cell" is not the raw material for making "gene". "gunpowder" is made by means of "chemistry", which is not the raw material for making "gunpowder".
