Answer: a) greater openness
Explanation: Gorbachev, who began with his changes by introducing "glasnost" and "perestroika", wanted to make reforms of the Soviet Union. These changes wanted to carry out economic and, above all, political reform, and to democratize the Soviet Union. One of these measures, glasnost, which in translates meant transparency, openness, meant democratization, creation of conditions for more open society and economy. In fact, these changes led to the end of the Soviet Union.
