choices.label: A B C D
choices.text: soil:planting coal:electricity generation outline:speech foundation:architecture
explanation: an "aircraft route" is a route that an aircraft "flies". "planting" is done on "soil", and "soil" is not a route of "planting". "electricity generation" requires "coal", but "coal" is not a route for "electricity generation". "speech" is made by the speaker according to the "outline". "architecture" needs "foundation" as the foundation, "foundation" is not a route of "architecture".
