Read the following passage and then answer the question: "food at camp was simple fare usually consisting of meat, coffee, sugar, and hardtack--a type of biscuit, but varied from that, depending on the side for which the soldiers fought. a union soldier might have salt pork, fresh or salted beef, coffee, sugar, salt, vinegar, dried fruit and vegetables. and if it was in season, they might have fresh carrots, onions, turnips and potatoes. a confederate soldier typically had bacon, corn meal, tea, sugar, molasses and the very occasional fresh vegetable. one food-related advantage the union had was an organization nicknamed “the sanitary” that made health and nutrition for the soldiers a top priority. the main roles of “the sanitary” were to find and distribute food and to have a knowledge of the availability of foods during specific seasons as well as how to preserve and transport that food. these tasks were somewhat overwhelming, though, considering there were more than 2 million soldiers fighting for the union. at times, too, deliveries would be interrupted by weather or poor transportation and soldiers would forage the countryside for food." what was hardtack? question 3 options: a type of gun a type of ammunition a type of biscuit a type of military maneuver
