question: scale:weight
choices.label: A B C D
choices.text: water:buoyancy map:distance table lamp:brightness ruler:length
explanation: a "scale" is used to measure the "weight" of an object. "water" has "buoyancy", which is the inherent characteristics of "water". the "distance" between places can be calculated through a "map", and the "map" is not a tool for measuring the "distance". the "table lamp" can provide "brightness" when energized, and the "table lamp" is a measuring tool to provide "brightness". a "ruler" is used to measure the "length" of an object.
