Converted factories from civilian to military production. Output of factories tripled! Which board oversaw this?

• A. Office of War Information
• B. Department of Defense
• C. Bureau of Industry and Security
• D. War Production Board

Answer: (D)

The main idea is how the United States organized and sped up industrial production for the war effort. The War Production Board was the federal body created to direct and prioritize war manufacturing, allocate scarce raw materials, and guide the conversion of peacetime factories into military producers. By coordinating factories, it oversaw turning civilian plants into facilities making weapons, vehicles, ships, and other war materiel, standardizing parts to speed production, and setting output goals. This centralized planning and mobilization is why factory output could rise so dramatically, even tripling in some periods as industry shifted focus from consumer goods to defense needs.

Other options refer to roles like propaganda, military operations, or security and export controls, which aren’t about coordinating and boosting overall war production in the same way.
