A) South Carolina benefited economically from the large numbers of South Carolinians involved in highway construction; other areas of the country did not have as many residents directly involved in the building of highways.
B) In addition to climate and culture, the interstate highway system helped draw people to South Carolina; other areas lacked the state's unique combination of features to attract visitors.
C) Because of highway construction, South Carolina's population was concentrated in urban areas; in other parts of the country, the population spread out from urban areas as a result of highways.
D) As industry took over as the leading sector of South Carolina's economy, highway construction became a vital component; other areas of the country came to depend more and more on agriculture as a result.
