During World War I, two revolutions took place in Russia while Russia was at war with Germany. Vladimir Lenin, leader of the Bolshevik Revolution, said: There can be no doubt that our army is absolutely in no condition…to beat back German offensive successfully… Source: V. I. Lenin, Collected Works, 4th English Edition, Progress Publishers, Moscow, 1964, p.447. What did this mean/show?

The statement means two things:

The first is that Lenin believed that Russia should withdraw from the war, instead of trying to defeat Germany.

The second is that Lenin realized that the weak state of the Russian army, the lack of popular support of the war, and the general disorder of the tsarist administration were conditions favorable for the emergence of a revolution. In the end, Lenin used this unfavorable conditions to his favor, and was successful in bringing about a revolution that lasted for seven decades.

i believe the answer is:

-   william jennings bryan is a democrat while mckinley was a republican

at that time, the segment of population that choose for democratic party were the voters with low economic background and vice versa

- william jennings has support of populists and wants to have inflation to farmers while mckinley has support of bankers and businessmen , doesn't want inflation

the fixed value of gold make the large business able to stack up their gold without   being worried that it would devaluated.

- william jennings supported the silver standard while mckinley supported the gold standard

according to jenning, using other metal beside gold could the poor people to have more purchasing power and them advance in the society.
