Final answer:
Russia's incapability to fight in WWI was due to incompetent leadership, poor infrastructure, including inadequate railroads, and low domestic morale that led to widespread dissent and revolution.
Step-by-step explanation:
During World War I, Russia experienced several major obstacles that severely hindered its war effort. Incompetent leadership, led to enormous casualties and prisoners of war, which was exacerbated by the lack of supplies and poor infrastructure.
The Tsarist government, under Nicholas II, struggled to keep up with the logistical demands of modern warfare including inadequate transportation systems, such as railroads, to mobilize troops and distribute food to civilians, leading to widespread riots and discontent.
Additionally, the war had a detrimental effect on domestic morale, with soldiers acutely aware of the suffering and shortages back home, resulting in low morale and high rates of desertion. This environment of despair contributed to the eventual overthrow of the Tsarist regime, with increasing revolutionary sentiments among the populace.
