Question: When is Ignat Solzhenitsyn's father's birthday?
Sentence (from "Aleksandr Solzhenitsyn"): Although the reforms brought by Nikita Khrushchev freed him from exile in 1956, the publication of "Cancer Ward" (1968), "August 1914" (1971), and "The Gulag Archipelago" (1973) beyond the Soviet Union angered authorities, and Solzhenitsyn lost his Soviet citizenship in 1974.
Relevant evidence: No
