Answer:
B
Step-by-step explanation:
This leaflet is responding to the demand for medical supplies and nurses to treat sick and wounded soldiers.
The excerpt mentions the United States Sanitary Commission and refers to a "Great Fair" being held in Philadelphia on behalf of the commission. The Sanitary Commission was a civilian organization that provided medical care and supplies to soldiers during the American Civil War. The purpose of the "Great Fair" was to raise funds for the commission, which indicates that the leaflet is responding to a need for medical assistance for sick and wounded soldiers.
Option A, "the domestic disorder, such as bread riots, caused by scarcity and hardship," is not mentioned in the excerpt. Option C, "the vast scale of property destruction, particularly in cities, caused by passing armies," is also not mentioned in the excerpt. Option D, "the pollution of waterways and landscapes by armaments, casualties, and troop movements," is not directly mentioned in the excerpt, but it could be related to the need for medical assistance for soldiers. However, the specific focus of the leaflet is on the need for medical supplies and nurses, so option B is the most accurate response.
