Which statement is true regarding the consequences of the october revolution in russia?

on november 6 and 7, 1917 (or october 24 and 25 on the julian calendar, which is why the event is often referred to as the october revolution), leftist revolutionaries led by bolshevik party leader vladimir lenin launched a nearly bloodless coup d'état against the duma's provisional government.

i think the answer is the one about environmental and social health.

if i am correct the answer is going to be a) the federal program of reconstruction ended.
