How did Gorbachev's plan of perestroika change the Soviet government?

The correct answer to this question is:

"Individuals were permitted to own businesses and earn profits."

Mikhail Gorbachev was the General Secretary of the Communist Party of the Soviet Union from 1985 until 1991. Prior to assuming his office, a lot of attention went to creating up the nation’s military at the cost of development within the Soviet Union, which eventually destabilized the economy.

Gorbachev began reforming the Soviet Union by implementing policies to bring about individual freedom, bureaucratic transparency, and to motivate economic change.
