The answer is B: The opportunity to expand Spain's territory and spread Christianity.
Spain was eager for new resources of wealth and to spread Christianity on their new lands.
Creating tenant farms and sharecropping.
I believe the answer would be the last option. A resource has value, and people are willing to pay for it most likely because the resource is scarce. When a resource is not enough or the supply is low as compared to its demand, then most likely that price or value of it would increase.
Democrats were mostly Southern farmers and laborers. Those that moved to the west or labored in the west found it harder to get jobs because of Chinese laborers who would work for a lower wage. The North were more industrialized so they didn’t have to worry as much about losing their jobs to Chinese laborers. Also, during this time, Southern Democrats were still more openly racist than Northern Republicans, so pure racism may have played a role as well. The key here is to point out that the evidence was made by Democrats, so Americans passed the Exclusion Act mostly by Democratic concerns and beliefs.
