question: bamboo slice:knife:text
choices.label: A B C D
choices.text: computer:printing:books steel:machine:automobile heat:air conditioner:cooling land:shovel:crop
explanation: use a "knife" to engrave "texts" on the "bamboo slice". the "knife" is a tool, and the "bamboo slice" is a carrier. "printing" is not a tool. a "machine" is a tool, but "steel" is the raw material, not the carrier, of "cars". an "air conditioner" is a tool, but "heat" is not a carrier. use "shovels" to plant "crops" on "land". "shovels" are the tool and "land" is the carrier.
