D. Cities grew rapidly.

D. Cities grew rapidly.

The correct answer is:

D. Cities grew rapidly.

During the period between the Civil War and the 1920s, the U.S. experienced significant urbanization and industrialization. This led to a rapid growth of cities as people moved from rural areas to urban centers in search of employment opportunities in factories and industries. Factors such as the expansion of railroads, the rise of manufacturing, and the influx of immigrants contributed to the population boom in cities. Therefore, option D, "Cities grew rapidly," is the correct answer.
