Final answer:
The term 'Annexation of Texas' is not associated or is associated least with the other three terms or statements - Louisiana Purchase, Treaty of Guadalupe Hidalgo, and Gadsden Purchase.

On the other hand, the Annexation of Texas refers to the incorporation of Texas into the United States in 1845.
Step-by-step explanation:
The term 'Annexation of Texas' is not associated or is associated least with the other three terms or statements - Louisiana Purchase, Treaty of Guadalupe Hidalgo, and Gadsden Purchase.
The Louisiana Purchase, Treaty of Guadalupe Hidalgo, and Gadsden Purchase are all significant events in American history that involved the expansion of the United States' territory. The Louisiana Purchase refers to the acquisition of a large territory from France in 1803, doubling the size of the country. The Treaty of Guadalupe Hidalgo was signed in 1848, and it resulted in the Mexican Cession, which added territories such as California and New Mexico to the United States. The Gadsden Purchase, signed in 1853, further expanded the country's territory and established the U.S.-Mexico border.
On the other hand, the Annexation of Texas refers to the incorporation of Texas into the United States in 1845. While Texas' annexation is related to the expansion of American territory, it is distinct from the other three terms/statement mentioned. It preceded the Treaty of Guadalupe Hidalgo and occurred independently from it. It is also distinct from the Louisiana Purchase and the Gadsden Purchase, as it did not involve the acquisition of a large territory like those events did.
