I think your question means how did the discovery of gold contribute to the creation of the transcontinental railroad. There had been some movements toward westward settlement in the 1840s, but that trend accelerated dramatically with the discovery of gold in California. James Marshall's finding of gold at Sutter's Mill in California in 1848 led to a "gold rush" in the decade that followed, with 1849 seeing a huge influx of people to California. (Thus we refer to the '49ers.) The swift settlement of California added incentive to build a transcontinental railway. The Pacific Railroad Act of 1862 established the charter for doing that. The First Transcontinental Railroad was completed in 1869.
This is false. After driving the Chinese Nationalists to Formosa, Chiang Kai-shek was quick to set up an interim government with state officials coming from his inner-ranks.
Let me handle your first question -- always good to do one question at a time here. :-)
Prior to President Theodore Roosevelt, those who preceded him in federal government had tended to side with industry leaders, expecting laborers to fall in line and do the work for the good of the companies. In 1902, when there was a particularly tense strike by coal workers, Roosevelt invited both sides (labor leaders and management leaders) to the White House to negotiate. This was an example of the way he saw the role of government leadership as "steward" to the nation, mediating on behalf of everyone's interests, not just the interests of a powerful small group. His "Square Deal" policies were aimed at making things fair and square for the general public. An example of this would be how much land was set aside under his administration as national forests, national parks, national monuments, etc. He was seeking to protect the use of the land for all Americans' interests, rather than letting corporations tear into any land or forest they wanted in order to grab natural resources.
