Understanding MacGregor's Use of Sources

The excerpt describes a shift in Japanese ideology towards international trade and economic engagement. In the context of historical analysis, when assessing what type of outside source MacGregor uses, it is essential to recognize the elements of each option: a newspaper article and a historical letter.
