The correct answer is B. A major challenge facing the builders of the Transcontinental Railroad was crossing the Serra Nevada.

Explanation:

The Transcontinental Railroad route followed the main roads used for the opening of the West, the so-called Oregon Route, the Mormon Route and the California Route, and the Pony Express. Going from Council Bluffs (Iowa), it followed the Platte River through Nebraska, left the traditional route to cross the Rockies in the Great Divide Basin in Wyoming and then stop through northern Utah and Nevada in the Great Basin before crossing Sierra Nevada to Sacramento.

Six months after the Pacific Railroad Act, on January 8, 1863 Governor Leland Stanford ceremoniously laid the "first stone" to begin construction of the Central Pacific Railroad in Sacramento, California. The Central Pacific made great progress throughout the Sacramento Valley. However, they reduced the progress of construction, first by the foothills of Sierra Nevada, then by the mountains themselves and, even more importantly, by winter snowstorms.

answer: a parliamentary system is a system of democratic governance of a state where the executive derives its democratic legitimacy from its ability to command the confidence of the legislature, typically a parliament, and is also held accountable to that parliament. in a parliamentary system, the head of state is usually a person distinct from the head of government. this is in contrast to a presidential system, where the head of state often is also the head of government and, most importantly, the executive does not derive its democratic legitimacy from the legislature.

countries with parliamentary democracies may be constitutional monarchies, where a monarch is the head of state while the head of government is almost always a member of parliament (such as the united kingdom, denmark, sweden, and japan), or parliamentary republics, where a mostly ceremonial president is the head of state while the head of government is regularly from the legislature (such as ireland, germany, india, and italy). in a few parliamentary republics, such as botswana, south africa, and suriname, among some others, the head of government is also head of state, but is elected by and is answerable to parliament. in bicameral parliaments, the head of government is generally, though not always, a member of the lower house.

parliamentarianism is the dominant form of government in europe, with 32 of its 50 sovereign states being parliamentarian. it is also common in the caribbean, being the form of government of 10 of its 13 island states, and in oceania. elsewhere in the world, parliamentary countries are less common, but they are distributed through all continents, most often in former colonies of the british empire that subscribe to a particular brand of parliamentarianism known as the westminster system.
