Looking at the map, why would Russia's withdrawal impact the war in favor of Germany?

I don't know if there is answer choices, but it would be:

Germany would no longer have to fight two fronts, this being the Eastern Front.

Explanation:

During WW1 Germany was fighting both the Western and Eastern Fronts, and had launched an invasion of Russia, but failed. Russia would later withdraw in 1917 when the Russian Civil War began.

the answer is c. many americans held nativist or racist views

as general terms,  indian territory,  the indian territories, or  indian country  describe an evolving land area set aside by the  united states government  for the relocation of  native americans  who held  aboriginal title  to their land. in general, the tribes ceded land they occupied in exchange for  land grants  in 1803. the concept of an indian territory was an outcome of the 18th- and 19th-century policy of  indian removal. after the  civil war(1861–1865), the policy of the government was one of  assimilation.
