Read the following passage and answer the question.

In the years leading up to the Russian Revolution of 1917, the country had a succession of wars. These were, The Crimean War, The Russo-Turkish War, The Russo-Japanese War and The World War I. All of these required a lot from the state, including tax dollars and manpower. Russia suffered defeat in all, except against Turkey. This series of war caused great discontent among the people and caused suffering in the country's economy and
government.
Along with these wars, there were three major parties that contributed to the cause of the revolution. First, there were the peasants, who maintained the majority of the population in Russia. They were excessively poor and could barely escape famine from harvest to harvest. The population boom in Russia from 1867-1896 was felt most drastically by the peasants. The increase of 30 million people in less than 30 years was too great that the land to the peasants' disposal did not increase sufficiently. The government tried to help, but war took precedence. Second, there was a rise of the industrial working class. These workers were employed in the mines, factories and workshops of the major cities. They suffered low wages, poor housing and many accidents. Again, the government tried to help by passing factory acts to restrict the number of hours one could work. However, their efforts were at too small a scale to have any real effect. As a result, there were many strikes and constant conflicts between the workers and the police. Lastly, the tsar of Russia was the cause of much disapproval. Tsar Nicholas II was much more interested in his family life, than matters of the state. He had an obsession with retaining all his privileges and the belief that he was chosen by God to rule. Also, he didn't understand the forces of industrialization and nationalism that were growing throughout Russia. His disregard for the struggles of the people led them to lose faith in him and the long- standing tradition of autocracy. The people were not content and were ready to revolt. They just needed a good reason and a strong leader.

Read the given passage and answer the questions that follow.

Key factors influencing subway air pollution will include station depth, date of construction, type of ventilation (natural/air conditioning), types of brakes (electromagnetic or conventional brake pads) and wheels (rubber or steel) used on the trains, train frequency and more recently the presence or absence of platform screen-door systems. In particular, much subway particulate matter is sourced from moving train parts such as wheels and brake pads, as well as from the steel rails and power-supply materials, making the particles dominantly iron-containing.
To date, there is no clear epidemiological indication of abnormal health effects on underground workers and commuters. New York subway workers have been exposed to such air without significant observed impacts on their health, and no increased risk of lung cancer was found among subway train drivers in the Stockholm subway system.
But a note of caution is struck by the observations of scholars who found that employees working on the platforms of Stockholm underground, where PM concentrations were greatest, tended to have higher levels of risk markers for cardiovascular disease than ticket sellers and train drivers.
The dominantly ferrous particles are mixed with particles from a range of other sources, including rock ballast from the track, biological aerosols such as bacteria and viruses, and air from the outdoors, and driven through the tunnel system on turbulent air currents generated by the trains themselves and ventilation systems.
