Step-by-step explanation:
Rationing has the biggest impact on consumer goods during war times. During World War II, the government implemented rationing programs to control the purchasing of certain products. This meant that people were only allowed to buy a fixed amount of particular products, such as gasoline, food items, and clothing. Rationing was necessary to ensure that essential resources were available for the military and to prevent shortages for the civilian population.
