Input: Architecture
Around the beginning of the 20th century, a general dissatisfaction with the emphasis on revivalist architecture and elaborate decoration gave rise to many new lines of thought that served as precursors to Modern Architecture. Notable among these is the Deutscher Werkbund, formed in 1907 to produce better quality machine made objects. The rise of the profession of industrial design is usually placed here. Following this lead, the Bauhaus school, founded in Weimar, Germany in 1919, redefined the architectural bounds prior set throughout history, viewing the creation of a building as the ultimate synthesis—the apex—of art, craft, and technology.

At what century's start did revivalist fall into disfavor? 
Output: 20th


Input: Article: An exceptionally well preserved, carpet-like mosaic floor was uncovered in 1949 in Bethany, the early Byzantine church of the Lazarium which was built between 333 and 390.

Article: His next directorial feature was the Raiders prequel Indiana Jones and the Temple of Doom. Teaming up once again with Lucas and Ford, the film was plagued with uncertainty for the material and script. This film and the Spielberg-produced Gremlins led to the creation of the PG-13 rating due to the high level of violence in films targeted at younger audiences. In spite of this, Temple of Doom is rated PG by the MPAA, even though it is the darkest and, possibly, most violent Indy film. Nonetheless, the film was still a huge blockbuster hit in 1984. It was on this project that Spielberg also met his future wife, actress Kate Capshaw.

Question: What rating did 'Temple of Doom' receive?
Ans: PG
