Which of the following was NOT a debate held in the old Hall of the House?

The debates on healthcare policy were not held in the old Hall of the House because the significant discourse on healthcare in the United States primarily emerged much later, particularly during the 20th and 21st centuries. Prior to that, the old Hall of the House was the site of debates centered around issues pertinent to the 19th century, such as the war with Mexico, states' rights versus federal rights, and territorial expansion, all of which were significant matters during that time period. This context underscores why healthcare policy discussions do not belong in the list of debates previously conducted in the old Hall of the House.
