The appealing aspect of Harding's campaign slogan "return to normalcy" was primarily option B: people wanted to forget about the war and look to a normalized future. After the upheaval and trauma of World War I, followed by the devastation of the Spanish flu pandemic, many Americans were yearning for stability, predictability, and a return to the familiar routines of pre-war life. "Normalcy" represented a desire for peace, prosperity, and a resumption of everyday life without the disruptions and hardships of wartime. While options C and D highlight the challenges faced by Americans during that time, option B encapsulates the broader sentiment that Harding's slogan tapped into, offering a vision of comfort and reassurance to a war-weary nation.
