Final answer:
The Missouri Compromise was led by Henry Clay and aimed to maintain a balance between free and slave states.
Step-by-step explanation:
The surveying for the Missouri Compromise was not conducted by a specific person or group. Instead, the Missouri Compromise was led by Speaker of the House Henry Clay.
The Missouri Compromise, also known as the Compromise of 1820, brought Missouri in as a slave state and Maine as a free state. It also included the Thomas Proviso, which banned slavery north of the southern boundary of Missouri.
The compromise aimed to soothe northern concerns about the expansion of slavery and avoid disunion. The goal was to find a solution that would maintain a balance between free and slave states.
