Step-by-step explanation:
The period of Modernism is noted for its significant technological innovations in various areas, which helped define and shape the era. Particularly, the Brooklyn Bridge symbolized American technological achievement and served as an inspiration for Modernist art and literature. The leap in automobile manufacturing, propelled by figures like Henry Ford and the development of the assembly line, revolutionized personal travel and spurred the creation of roads and highways. This period also saw a surge in the mass production of phonographs, projection reels, and telephones, making technology more accessible and enabling the expansion of mass culture. Moreover, the Modernist era was a time of rapid growth in the publishing industry, evidenced by the prevalence of the paperback book, Book-of-the-Month clubs, subscription reading programs, and the popularity of literary magazines. Lastly, innovations in architecture, using materials like steel and plate glass, fostered the development of Modernist architecture with its emphasis on clean lines and minimalistic designs.
