Step-by-step explanation:
During World War I, in order to support the war effort, certain food items were added to restaurant menus. However, instead of adding unconventional items like dog and cat, eggplant and tofu, or rabbit and whale steaks, the focus was on conserving resources and reducing consumption of certain foods. For example, meatless Mondays and Tuesdays were implemented to reduce the consumption of meat, while wheatless and sugarless days were observed to conserve these resources for the troops. Additionally, rationing programs were introduced, limiting the amount of meat, coffee, butter, sugar, and other foods that civilians could purchase.
