Final answer:
The true statement about the International Style initiated by the Bauhaus building in Dessau is 'Both A and B', which pertains to the vast surfaces and different heights designed to serve the needs of the school, consistent with the functionalism and simplicity typical of the style.
Step-by-step explanation:
The International Style of architecture, which was influenced significantly by the Bauhaus building in Dessau, is characterized by several features according to the Dessau Bauhaus video. One of the primary attributes is its emphasis on volume over mass, along with the usage of lightweight, mass-produced industrial materials and a rejection of all ornament and color. The style also embraces repetitive modular forms and favors flat surfaces that often alternate with areas of glass, thereby prioritizing functionality over elaborate aesthetic accents.
A specific example of the International Style is reflected in Walter Gropius's Bauhaus school, which was designed with different heights to accommodate the various needs of the school, thereby integrating form with function. This design illustrates that the International Style could accommodate the functional needs of a structure while maintaining the aesthetic principles of simplicity and absence of ornamentation.
Therefore, the statement that is true about the new global style of architecture initiated by the Bauhaus building in Dessau would be 'Both A and B', which are the vast surfaces and different heights corresponding to the various needs of the school.
