This is a very poor question - your teacher, clearly, understands very little about the collapse of the USSR and Gorbachev and his reforms.
<span>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. </span>
<span>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. </span>
<span>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. </span>
Impeachment proceedings against the president came when Johnson breached the Tenure of Office Act by removing Edwin Stanton, Secretary of War, from the cabinet.
Limiting competition, this is why they're frowned on today.
It was predicted that James Earl Ray killed Martin Luther King Jr. due to his persuading speech. He was worried that if his speech touched many people's hearts and persuaded them against slavery, then slavery would end, but he WANTED to keep having slavery! So, before Martin's speech got slavery to end, he had to end Martin's mouth by taking away his life.
I hope this helps! :-)
