Final answer:
Modernization on the IU campus at the turn of the 20th century is indicated by architectural developments and adaptations to the Industrial Revolution's societal changes.
Step-by-step explanation:
A sign of modernization on the IU campus around the turn of the 20th century could be identified through architectural advancements and the institution's adaptation to societal changes brought about by the Industrial Revolution. Significant constructions or renovations, such as the original building of the school in 1928 and its subsequent remodels resulting in an architectural mashup, reflect the university's response to modernization. Additionally, the impact of the economic downturn of 2008 on educational institutions and the changes in American culture as explored by John and Helen Lynd in their study of Muncie, Indiana, serve as wider context for understanding the modernization of the IU campus.
