Immediately after the revolution of 1917, all artistic movements in the ussr were streamlined; artists and writers could only express themselves in ideologically "correct" forms. a. true b. false

True.

Explanation:

The Bolshevik Revolution of 1917 looked for thorough social change, leaving behind the old and "decadent" bourgeois social order and culture. A new culture and art had to reflect the values of the supposed new dominant class, the proletariat. So, literary works - poetry and prose -, and the arts - painting, sculpture and film - had to be ideologically "correct"  in conformity with that new vision. That was in the beginning of the Russian Communist Revolution, and it remained so until the mid -1980s in Soviet official practice, until the glasnost (openess) of Soviet leader Mikhail Gorbachev that brought fresh air into social and artistic life.
