Final answer:
The 1920s supported the inference of a shift towards more revealing and daring fashion, as seen with the rise of the 'flapper' style that emphasized comfort, movement, and a break from traditional female silhouettes.
Step-by-step explanation:
The inference about the 1920s that is supported by the illustration is d) The 1920s witnessed a shift towards more revealing and daring fashion. This era, often referred to as the 'Roaring Twenties', was a period of significant change in the social and cultural fabric of society. Women began to adopt fashions that were more comfortable and provided greater freedom of movement, symbolized by the iconic 'flapper' style. Dresses became shorter, typically extending just below the knee, and were designed to create a straight-line silhouette rather than emphasizing the female form. This change in fashion reflects the broader social trend towards modernity, including women's increased participation in the political and social spheres post the ratification of the Nineteenth Amendment, and the expansion of women's liberation to include new forms of social expression.
