Problem: Question: In what country did Melquiades Alvarez sutdy law? Passage:He studied Law at the University of Oviedo and collaborated with Asturian liberal newspapers. In 1898 he was elected to the Congress as Liberal candidate and was appointed Professor of Roman Law at the University of Oviedo. In 1899, he turned into Republican and in 1906 he was elected Republican congressman. He was one of the organizers of the Liberal Block in 1908 against the Conservative Prime Minister Antonio Maura and of the Republican-Socialist Conjunction in 1909. In 1912, he founded with Gumersindo de Azcarate and Jose Ortega y Gasset the Reformist Party and the League for the Spanish Political Education.

After the beginning of the Civil War, the revolutionary militias imprisoned and killed him.
