massive increase in traffic congestion
expanded use of railroads
passage of the interstate highway act
growth of suburbs
expansion of businesses related to travel

Explanation:

• Massive increase in traffic congestion: More cars (from 8.13M in 1920 to 23.03M in 1930) mean more vehicles on roads, causing congestion.
• Growth of suburbs: Increased car ownership allowed people to live farther from cities (suburbs) and commute, so suburbs grew.
• Expansion of businesses related to travel: More cars mean demand for travel - related businesses (like gas stations, repair shops, motels) increased.
• Expanded use of railroads: Cars reduced railroad use (people shifted to cars), so this is incorrect.
• Passage of the Interstate Highway Act: The Interstate Highway Act was passed in 1956, not the 1920s, so this is incorrect.

Answer:

• massive increase in traffic congestion
• growth of suburbs
• expansion of businesses related to travel
