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.
The correct answer to this open question is the following.
Te question does not mention any individual in specific, so we assume that we choose the individual we like to write the testimonial.
We choose Dr. Martin Luther King Jr. He was an important figure and led the civil rights movement in the United States. He followed the ideals of liberty and tolerance and influenced millions of people. On his positive side, Dr. King could congregate thousands of people to the civil rights movement cause. He set the example. He was at the very front of the protests and marches. One very good thing he had was that he supported peaceful demonstrations, never violent protests. His "Letter From the Birmingham Jail" and "I Haad a Dream" speech, have influenced modern leaders around the world.
On the negative side, probably he could have been more open and tolerant to negotiate with authorities or to join forces with other black leaders such as Malcolm X, that although he used violence in his protests, the union of more African American leaders could have taken the movement to different dimensions and accomplishments.
