question: Hvilket af følgende er en bemærkelsesværdig undtagelse fra det trestrengede system i mange stater?
context: Three-tier system (alcohol distribution)
  Den eneste stat med et privat drevet detailhandels- og distributionssystem, som ikke kræver nogen form for treleddet system, er staten Washington. I Washington kan detailhandlerne købe alkoholholdige drikkevarer direkte fra producenterne, forhandle om mængderabatter og selv opbevare deres lagerbeholdning. Treklassesystemet er dog stadig i vid udstrækning en realitet i Washington på trods af, at der ikke findes en lov, der kræver det.
context_en: Three-tier system (alcohol distribution)
  The only state with a privately operated retailing and distribution system that does not require any form of three-tier system is the State of Washington. In Washington, retailers may purchase alcoholic beverages directly from producers, may negotiate volume discounts, and may warehouse their inventory themselves. However, the three-tier system largely remains in fact a reality in Washington despite the lack of a law requiring it.
