The correct answer is B; Chinese immigrants played a significant role in the construction of the Central Pacific track of the Transcontinental Railroad, while Irish immigrants played a significant role in the construction of the Union Pacific track.
Further Explanation:
It was the Chinese who made the most significant roles in the construction of the Central Pacific track for the Transcontinental Railroad. The company began with Irish and white workers but they had severe shortages when the white men just did not show up to work. They then began recruiting immigrants and specifically hired 26 Chinese in the beginning. They worked so well that they hired more until over 90% of the workers were Chinese immigrants. They made approximately 26-30$ per month. They began a strike that lasted for 8 days for more pay and food, but the strike ended without the workers getting any extra money or food.
The Irish immigrants actually started out with the Central pacific track but there were issues and they left it for the Union Pacific. Labor was in short supply when the company started on the Union Pacific track and men went there for work. They had issues with sanitation in the camps and had issues with water borne illnesses. They did pay more to the Irish immigrants than to the Chinese immigrants which led to distrust.
