Question

How did “car culture” in the United States affect the new migration of the 1950s?
The new highway system, which resulted from the car culture, made it easier for people to migrate from the North and East to the South and West.
Only wealthy people could afford cars, so the people involved in the new migration tended to be wealthy with a lot of disposable income.
As car ownership increased, more people stayed put and only traveled to distant places during vacations, which brought the new migration to an end.
Cars helped urban centers and their downtown areas prosper, which made people want to migrate to Eastern cities during the 1950s.

Answer 1

The first statement is correct.

Explanation: Widespread car ownership and the federal highway program (especially the 1956 Interstate Highway Act) made long-distance travel and relocation far easier and faster. That increased mobility helped the postwar “new migration” to the Sunbelt (South and West) — along with jobs, lower taxes, and air-conditioning — and supported suburbanization. The other choices are inaccurate: cars were no longer a luxury limited to the wealthy by the 1950s; greater car ownership increased mobility rather than ending migration; and cars tended to spur suburban growth and hurt some downtowns, not cause a migration into Eastern urban centers.
