question: investigate:clue:case
choices.label: A B C D
choices.text: evaluation:ranking:singer locate:position:map navigation:gps:car search:keywords:webpage
explanation: "cases" will be "investigated", and "clues" are required for "investigation" and "cases". "review" and "singer" do not necessarily need "ranking". "locate" "position" can be passed through "map", but the order is inconsistent with the query. "car" uses "gps" "navigation", not "navigation" "car". "webpage" will be "searched", and "keywords" are required when "searching" and "webpage".
