I want to know the answer to the following question:
Which magazine advocated for Galician nationalism?
All the background I'm provided with is that "Vicente Risco and Ramón Otero Pedrayo were outstanding cultural figures of this movement, and the magazine Nós ('Us'), founded 1920, its most notable cultural institution, Lois Peña Novo the outstanding political figure.". Is that enough to answer the question?
Answer: yes
