The correct answer is: "To take advantage of the many natural resources found in Siberia".
This was the main reason behind the construction of the <em>Trans-Siberian Railway</em>. It connected the European part of Russia with the provinces located in the far east.
During the first World War, Russia suffered a blockade from Germany and Turkey. As a consequence of this, the Trans-Siberian Railway gained massive importance as it was a way of communication and sourcing between Russia and its eastern allies.
The "White Man's Burden" was an idea revolving around the concept that it was the moral and social responsibility of European citizens to spread their values, religion, and system of government to countries and territories they deemed as "inferior."
The goal in taking up this "burden" was to civilize nations of citizens who did not have these systems already in place.
In this case, from the western perspective, the answer would relate to seeing this idea as a positive element of society. Since there are no option choices in the question this is my best educated guess.
