question: fries:potatoes
choices.label: A B C D
choices.text: popcorn:corn vegetables:grain salad:fruit red wine:sorghum
explanation: "potato" is the raw material of "fries", and "potato" is a specific thing. "corn" is a raw material for "popcorn", and "corn" is a specific thing. "vegetables" can be "grains", and "grains" can also be "vegetables", such as potatoes, which can be either "grains" or "vegetables". "fruit" is the raw material of "salad", and "fruit" is a concept but not a specific item. "sorghum" is not the raw material of "red wine", but grapes are the raw material of "red wine". There is no obvious logical relationship between "red wine" and "sorghum".
