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? us businessmen inflicted huge armies of foreigners on an unsuspecting america. the hordes of unskilled laborers brought in by mine and mill owners became an “alien invasion,” which i believe threatened america’s future. one way in which us businessmen acquired workers for their mines and mills was by offering contracts to groups of immigrants. if they could make more money or build more railroads, us businessmen didn’t care what happened to the america of our founders.

The sentence that best summarizes in an objective way the idea of the paragraph is "One way in which US businessmen acquired workers for their mines and mills was by offering contracts to groups of immigrants."

Explanation:

The paragraph uses words with negative connotation to show bias against immigrants that came to America to work. It mentions "alien invasion", "huge armies of foreigners".

In order to change this paragraph into an impatial sentence, the correct option is  "One way in which US businessmen acquired workers for their mines and mills was by offering contracts to groups of immigrants." since it does not use words that carry a negative effect.

The rest of the options are incorrect as they use bias against foreign immigrants. Examples: "inflicted huge armies of foreigners", "The hordes of unskilled laborers", "US businessmen didn’t care what happened to the America of our founders"
