All of the following factors led to the growth of Texas cities at this time EXCEPT: a. There was massive post-war migration from settlers throughout the South, whose states had experienced much more destruction from the war than Texas had. b. Most people moving to Texas were poor and had to live in the city so that they could find work and take advantage of cheaper living expenses. c. More people were moving to Texas, which meant an increased need for local goods and services, leading to increased business opportunities. d. The railroads provided easier and quicker transportation for people wanting or needing to travel in and out of the cities.
