Final answer:
The reader can infer that the author of 'The Autobiography of an Ex-Colored Man' might have personal experiences or knowledge similar to those described in the novel, as it is a roman à clef.
Step-by-step explanation:
Because The Autobiography of an Ex-Colored Man is an example of a roman à clef, the reader can logically infer that the author may have had actual experiences with issues of race or known someone similar to the narrator who had. A roman à clef is a novel in which real people or events appear with invented names. Therefore, the experiences depicted in the book could be closely related to real events and possibly to the author's personal experiences or observations. However, it does not necessarily indicate that the book is an exact autobiography of the author, nor does it imply that the narrator is unreliable or that the story is a copied historical document.
