choices.text: leather bag:zipper:make bridge:steel:welding furniture:wood:paint song:notes:combination
explanation: "building" can be made of "cement", and the decoration of a "building" needs "whitewash". some "leather bags" have "zippers". "steel" is an integral part of the "bridge", but "welding" is a manufacturing process, not a way to decorate the "bridge". "furniture" can be made of "wood", and "paint" is used to decorate "furniture". the notation for the sound duration or high pitch of a "song" is a "note".
