Take the following as truth: After the high emotion of de Gaulle's march down the Champs-Elys??es, the business of post-war reconstruction, though boosted by the generous aid of the Americans' Mar?­shall Plan, proved arduous, and the wartime alliance of de Gaulle's conservatives and the Communist Party soon broke down.
Then the following statement: "The Marshall Plan was not concocted until 1918." is true, false, or inconclusive?
Answer: Inconclusive
