Who helped to build the Transcontinental Railroad?

• A. Chinese Workers
• B. Irish Laborers
• C. Former Slaves
• D. Mexican Miners

Answer: (A)

The key idea is recognizing who did the bulk of the work on the Central Pacific section that crossed the Sierra Nevada to connect the nation. Chinese immigrants provided the majority of the labor for this part of the Transcontinental Railroad, taking on some of the most grueling and dangerous tasks—tunneling through solid rock, blasting through mountains, and laying long stretches of track under harsh conditions and often lower wages. Their skilled, steady labor was crucial to pushing the railroad westward and completing the crossing in 1869.

While other groups, like Irish laborers and workers from various backgrounds, contributed to railroad projects in different regions or times, the Central Pacific relied most heavily on Chinese workers. That heavy reliance makes Chinese workers the best answer to who helped build the Transcontinental Railroad.
