Answer 1

Gorbachev attempted to restructure the political and economic system of the Communist Party.  He called the reconstruction of the economy "Perestroika" and "Glasnost"  was the reference of attempts to make the government more open.

An example of Glasnost would be allowing contested elections to take place and allowing open public discussions.
