Assertion: Gorbachev tried to reform the collapsing system of the USSR but lost support on all sides and divided public opinion.

Reason: Gorbachev diagnosed the problems of the system correctly and became popular.

The Assertion is correct but the Reason is incorrect.

Gorbachev’s reforms promised to deal with the many problems that the Soviet was facing at the time. Gorbachev promised to reform the economy, catch up with the West, and loosen the administrative system. However, there were sections of people who felt that his reforms were inadequate and another section, the Communist Party felt that he was eroding their powers and privileges. Due to this tug of war, Gorbachev lost support and created a divided public opinion.
