Final answer:
The thesis statement is that the narrator's attempt to create impartiality depends on point of view and rhetorical devices.
Step-by-step explanation:
The thesis statement regarding the narrator's attempt to create impartiality through point of view and rhetorical devices is that the success of the author in achieving impartiality depends on the narrative's point of view and the use of rhetorical strategies. The narrator's choice of point of view, be it an omniscient or character narrator, and the use of rhetorical devices such as language choices and tone, can either create an objective and impartial account or introduce bias and subjectivity. The thesis statement expresses the opinion on the author's success in achieving impartiality based on these factors.
