Tell me whether these are examples of twentieth-century architecture and design: modernism, art deco, art nouveau, post-modernism, victorian

Modernism, post-modernism, art nouveau, victorian and art deco are all examples of twentieth-century architecture and design. Art nouveau and victorian can also be considered to be examples of nineteenth-century architecture and design, as art nouveau began circa 1890 and ended circa 1910, while victorian began circa 1837 and ended circa 1901, coinciding with the reign of Queen Victoria of Great Britain.
