Final answer:
A primary source like a diary entry provides a personal perspective on historical events, whereas official documents such as treaties offer direct evidence of political agreements. Critical assessment of these sources is necessary for understanding their context and reliability.
Step-by-step explanation:
Two examples of information that a primary source provided include a diary entry that offers a personal account of daily life during a specific historical period and a government document like a treaty which details the terms agreed upon by the parties at that time. For instance, if we consider a diary entry from a soldier during the American Civil War, it could provide insights into the experiences and sentiments of those on the battlefield. Similarly, a primary source such as the treaty ending a war, like the Treaty of Versailles, would give us direct information regarding the political decisions and territorial changes that resulted from World War I.
It is essential to critically assess these sources by considering the author, audience, intent, and context. By doing so, one can gain a deeper understanding of the motivations and circumstances that influenced the creation of the source. Finally, sources like newspaper coverage during the event or eyewitness accounts further solidify our interpretations
