Answer: The correct option is: "Cities grew rapidly as both immigrants and native-born citizens sought higher paying jobs".
Step-by-step explanation:
The historical period between 1865 and 1920 was a era of great changes in American society. Rise of industrialization, surge of immigration, reconstruction of the country after the Civil War are some examples of important events occurred during these years. Indeed, cities grew rapidly thanks to industrialization (many people left rural areas and established in the cities) and those immigrants arriving from other countries; both natives and immigrants were looking for higher paying jobs.
