Read the paragraph from history of the united states, by charles and mary beard. so eager were american businessmen to get an enormous labor supply that they asked few questions about the effect of this "alien invasion" upon the old america inherited from the [founders]. they even stimulated the invasion artificially by importing huge armies of foreigners under contract to work in specified mines and mills. there seemed to be no limit to the factories, forges, refineries, and railways that could be built, to the multitudes that could be employed in conquering a continent. which of the following best summarizes this biased paragraph objectively? a. us businessmen inflicted huge armies of foreigners on an unsuspecting america. b. the hordes of unskilled laborers brought in by mine and mill owners became an “alien invasion,” which i believe threatened america’s future. c. one way in which us businessmen acquired workers for their mines

The correct answer is B.

The paragraph approaches an historical fact from a subjective viewpoint. When multinationals started displaying their business model of massive hiring in the times of the Industrial Revolution, national labor was not enough to provide the required labor supply that was growing with no limits. The author, tells how this supply was fulfilled by fostering the arrival and hiring workers from abroad to cover those job positions.

He calls this hiring of foreigners an "alien invasion", which is spoiling the old original America inherited from the Founding Fathers. He keeps using the term invasion throughout the paragraph, which denotes his opposition to the proliferation of the mentioned business model and practices. He also ends up defining the enterprises as totally shameless when using expressions such as "there seemed to be no limit...".
