Transcript text: Thesis
The $\qquad$ is the particular viewpoint or theory for which a historian provides support. The $\qquad$ is composed of historical sources that provide support for a historian's viewpoint or theory.
Because historical events are not directly observable, and the evidence necessary to support the thesis of an argument may be fragmented or incomplete, it is $\qquad$ to prove a thesis with absolute certainty. In light of this, it is the task of historians to provide as $\qquad$ evidence as possible to support their theses, thereby providing the most convincing, well-supported interpretation of historical events.
