One way to determine the main cause of the war is to analyze primary and secondary sources, such as historical documents, textbooks, or scholarly articles. These sources can provide insights into the motivations of Americans at the time and the factors that contributed to the conflict.

Additionally, researching the concept of manifest destiny and understanding its influence on American politics and expansion can provide further evidence to support the answer choice. By examining historical events and the perspectives of both Americans and Mexicans, you can arrive at a conclusion regarding the main cause of the Mexican-American war.
