Final answer:
John Quincy Adams played a significant role in the development of transportation infrastructure in the United States through his endorsement of roads and canals. Charles Carroll, however, did not contribute to the development of transportation infrastructure.
Step-by-step explanation:
Both Charles Carroll and John Quincy Adams played significant roles in the development of transportation infrastructure in the United States. Adams, during his presidency, championed the American System which included plans for a broad range of internal transportation improvements, such as roads and canals, to facilitate commerce and settlement in the West. He broke ground for the Chesapeake and Ohio Canal in 1828.
On the other hand, Charles Carroll did not play a role in the development of transportation infrastructure through the Baltimore and Ohio Railroad. Although he was a prominent figure and a signer of the Declaration of Independence, he did not contribute to the building of the railroad.
