I want to know the answer to the following question:
What ws the final day of the 19th Party Conference?
All the background I'm provided with is that "Detailed proposals for the new Congress of People's Deputies were published on October 2, 1988, and to enable the creation of the new legislature the Supreme Soviet, during its November 29–December 1, 1988, session, implemented amendments to the 1977 Soviet Constitution, enacted a law on electoral reform, and set the date of the election for March 26, 1989.". Is that enough to answer the question?
Answer: no
