question: wood:paper:easel
choices.label: A B C D
choices.text: flour:steamed bread:steamer silver:jewelry:wineware concrete:steel:bridge cotton:duck down:quilt
explanation: "wood" is the raw material of "paper" and "easel". "flour" is the raw material of "steamed bread", and there is no obvious logical relationship between "flour" and "steamer". "silver" is the raw material for "jewelry" and "wineware". both "concrete" and "steel" belong to the raw materials of buildings, and "concrete" is not the raw material of "steel". both "cotton" and "duck down" are fillers, and "cotton" is not the raw material of "duck down".
