Correct. The answer is b. The author uses the Mexican cowboys, or vaqueros, in California who made good wages herding cattle on long drives until the 1880s to demonstrate how the development of big business in the West eroded the economic status of many westerners. After that time, when the railroads and large-scale ranchers replaced the open range, the vaqueros’ skills declined in value and their wages decreased. Many vaqueros were driven out of the cattle industry altogether, and went to work as migrant farm laborers.
