question: language:communication
choices.label: A B C D
choices.text: smile:express singing:happy text:record foraging:satisfying hunger
explanation: "language" is a tool for "communication". "smile" is used to "express" kindness, but "smile" is not a tool and does not match the query. "singing" can express "happy", but "singing" is not a tool. "text" is a tool for "recording". "foraging" refers to birds and beasts searching for food everywhere, and "foraging" is to "satisfy hunger".
