PLEASE HELP!!!!! When Russia lost ( the Decemberist Revolt/ world war I/ he Crimean war ) Czar Alexander II realized that his nation’s lack of industrial progress was a problem that needed to be remedied. To achieve that end, the czar introduced reforms to ( expand of railroad/ ban the programs/ manufacture ammunition ). In addition, he also introduced measures to ( expand the programs/ emancipate serfs/ increase absolute power ).
I think it is The Crimean War, Expanse of the railroad and, increase absolute power. I am not sure about the third one. Hope this helps.
