The correct answer is A) The poster uses a mother and her child as an appeal to authority in an attempt to convince the viewer to buy war bonds.
The statement that best explains why the poster's argument is NOT proven logically is "The poster uses a mother and her child as an appeal to authority in an attempt to convince the viewer to buy war bonds."
Unfortunately, you forgot to attach the poster. However, we did deep research and found the poster that was created by the United States Office of War Information in the times of World War II, during the presidency of Franklin D. Roosevelt.
The poster appeals to the emotion of the American people, so it used pathos, the appeal to the emotion to convince audiences. It does not use logos, because there are no arguments to make people think in logical reason. It moved the emotion of the American citizens to make them buy war bonds, make them think that if they did not, many women and children would die victims of the war.
When the United States entered world war ll, it affected the lives of Americans in many ways. People were asked to conserve resources, such as food, oil, and gas. The government also encouraged people to purchase war bonds to help the country financially during the war.
