Teacher: Now, understand the problem? Solve this instance: Passage: As of the first decade of the 21st century, contemporary neoclassical architecture is usually classed under the umbrella term of New Classical Architecture. Sometimes it is also referred to as Neo-Historicism/Revivalism, Traditionalism or simply neoclassical architecture like the historical style. For sincere traditional-style architecture that sticks to regional architecture, materials and craftsmanship, the term Traditional Architecture (or vernacular) is mostly used. The Driehaus Architecture Prize is awarded to major contributors in the field of 21st century traditional or classical architecture, and comes with a prize money twice as high as that of the modernist Pritzker Prize.
