Why did the rulers of Moscow work with the Mongols?

i think this is it

Explanation:

When the Mongols invaded the lands of Kievan Rus' in the 13th century, Moscow was an insignificant trading outpost in the principality of Vladimir-Suzdal. Although the Mongols burnt down Moscow in the winter of 1238 and pillaged it in 1293, the outpost's remote, forested location offered some security from Mongol attacks and occupation, while a number of rivers provided access to the Baltic and Black Seas and to the Caucasus region.[10]

More important to the development of the state of Moscow, however, was its rule by a series of princes who expanded its borders and turned a small principality in the Moscow River Basin into the largest state in Europe of the 16th century.[11] The first ruler of the principality of Moscow, Daniel I (d. 1303), was the youngest son of Alexander Nevsky of Vladimir-Suzdal. He started to expand his principality by seizing Kolomna and securing the bequest of Pereslavl-Zalessky to his family. Daniel's son Yuriy (also known as Georgiy; ruled 1303-1325) controlled the entire basin of the Moskva River and expanded westward by conquering Mozhaisk. He then allied with the overlord of the Rus' principalities, Uzbeg Khan of the Golden Horde, and married the khan's sister.

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.
