Final answer:
A beginning example of Modernity in 'Preludes' includes the poem's experimental form that reflects Modernist values such as fragmentation and alienation. The Modernist period in the 1920s was marked by a transformation in the arts and social attitudes, with a push for innovation and rejection of traditional narratives and authority.
Step-by-step explanation:
A beginning example of Modernity in 'Preludes' by T.S. Eliot, written in 1910-11, can be found in Eliot's experimentation with form and imagery, which reflects Modernist tendencies. The fragmented imagery and the unconventional structure of the poem represent a break from past poetic forms, thus mirroring the Modernist imperative to 'Make it new!' as famously instructed by Ezra Pound. In 'Preludes', the portrayal of the urban landscape is infused with a sense of disjointedness and alienation, characteristics that are indicative of Modernist literature's response to the rapid changes of the time.
During the 1920s, Modernity encompassed a transformation in social attitudes and arts, reacting against pre-war values and pursuing innovation. This was a period where the arts moved away from traditional narrative structures and moral messages, favoring instead abstract forms and skepticism towards established authority. In literature, Modernity is exemplified by the diversification of styles, as writers increasingly sought to experiment with their art in ways that could challenge ordinary readers.
