Step-by-step explanation:
The questions provided appear to relate to different historical events and facts in the United States. For instance, the peaceful solution regarding problems with the British and French would pertain to President Madison's era. In contrast, the statement about the Louisiana Purchase doubling the territory of the United States is related to an early 19th-century event that is indeed true. Regarding the Lecompton Constitution in the Kansas territory, its proposal was pro-slavery and thus did not show the dominance of the Free Soilers, who were anti-slavery settlers.
