In 1985, mikhail gorbachev outlined his plans for the policy of perestroika. what was reflected in the provisions of this policy?

This is a very poor question - your teacher, clearly, understands very little about the collapse of the USSR and Gorbachev and his reforms. 

These 'provisions' are not what Perestroika was about - your teacher, and possibly your text book, has confused two completely separate and distinct Soviet reforms - Perestroika and Demokratizatsiya (democratisation). All of the 'Provisions of Perestroika' that you have listed are, in fact, parts of the Demokratizatsiya reforms. 

Perestroika was the restructuring of party and state organisations, but particularly enterprises, factories, mines, collective farms and other 'means of production'. It sought to re-structure the command economy making it more efficient and better able to compete globally and to meet the needs of Soviet consumers and other end users. 
What Perestroika demonstrated was the gross inefficiencies of the Soviet Command Economy, and that the economic base of the country needed frastic and radical reforms - not that the Communist system itself was failing.
