question: bed:guest room
choices.label: A B C D
choices.text: plane ticket:airport smartness:iq desk:classroom car:driver
explanation: "beds" are part of a "guest room". the credential for boarding at the "airport" is the "plane ticket", which is not part of the "airport". "iq" and "smartness" may be positively correlated, but "smartness" is not a component of "iq". the "desk" is part of the "classroom". a "driver" can drive a "car", which is not a component of a "driver".
