Why should the rise of socialism be studied in the background of the Russian Revolution?

Correct answer: Because socialist ideas had prepared the language of workers' question and class struggle

The governing concept is historical context: the Russian Revolution did not emerge in isolation. During the nineteenth century, industrialisation created poverty, insecure employment, long working hours and unequal ownership, while socialist thinkers criticised private control of production and explained society through class interests. These ideas supplied workers and revolutionaries with a language of exploitation, solidarity, equality and collective action. Russia later became the place where a revolutionary movement attempted to apply such ideas to government and economic organisation. Therefore option A is correct. Option B is wrong because socialism had a strong intellectual connection with Russia; C is absurd because weather did not cause the revolution; and D is false because workers' politics developed widely in Europe.
