There are three main reasons why the Provisional Government fell and the Bolsheviks did not (well, not for 70 years). 1) Democratic legitimacy. The Provisional Government was basically the reconstituted State Duma - only a few monarchists were arrested, and they were not elected to office by the majority of the Russian people.
The Petrograd Soviet, and the composition of the Congress of Soviets - and the later Supreme Soviet - provided the Bolsheviks with a democratic veneer. This veneer they would, in time, lay on top of their imposition of Communist rule across Eastern Europe. 2) Failure to listen.
The Provisional Government failed to address the reasons that the Russian people rose up against the Tsar; Russia's involvement in WWI, the land question, hunger in the cities and long hours and low pay - along with poor working and living conditions for Russia's factory workers. Nor did they heed calls for elections for a Constituent Assembly - saying that they would wait until after ... more.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
