The leader of the Mensheviks was Martov.  

The Mensheviks were the moderate fraction of the Russian Social Democratic Labor Party that emerged from its second congress in the summer of 1903 after the dispute between Vladimir Lenin and Yuli Martov. Differentiated current within Russian Marxism, it became a separate party in 1912. It had a prominent role in the inter-revolutionary period of 1917, both for its control of the Petrograd Soviet and the All Russian Central Executive Committee and for its participation in the provisional government overthrown in the October Revolution.

when studying cause and effect, historians usually group the causes into different categories. for example, cultural causes reflect how a society’s literature and art convey the way the society saw itself in relation to the rest of the world. another resource that historians use to understand society is pop culture, which tells them the trends and ideas that are preferred by the common people. when studying cause and effect, it’s important to remember multiple causation, or the idea that an effect could have several causes and vice versa.  

the correct option is “cultural causes” since art and literature are related to the culture of a place. culture is determined by literature, art, music.

the correct option is “pop culture” since it reflects the likes and ideas of common people whereas the rest of the options do not focus on common people.  

the correct option is “multiple causation” since it refers to the idea that events are caused by multiple reasons, not just a single one.  

the correct answer is ''the programs costs have risen dramatically in the recent past'' hope this !
