The two statements that demonstrate correct paraphrasing of the quotation are:
The health of our economy is dependent on the health of our national transportation arteries. More economical choices can be achieved through increased competition and decreased regulation. Three-fourths of our citizens live in cities, and government aid is needed to help relieve the congestion in these areas (Kennedy, 1963).
The current assessment of our economy reveals that there is a need for improvements to our transit system and the removal of regulatory restrictions placed upon this system. Public transportation is just as important as other public services, affects a majority of our citizens, and is in dire need of governmental aid (Kennedy, 1963).
These statements capture the main ideas of the original quotation while presenting them in different words and sentence structures.
