Answer:
C. Tone and viewpoint
Step-by-step explanation:
This question was asked from the book "The Riddle of the Rosetta Stone" by James Cross Giblin. The book is an archaeological and historical material centered upon the helping the reader to better understand the history of Ancient Egyptian hieroglyphs; Giblin brings his reader closer to the historical context of the time by the usage of photographs, illustrations and engravings. Giblin would further employ the usage of tone and viewpoint to carry the reader along and bring them to a perspective where they can properly appreciate the literary work.
Hence, option C (Tone and viewpoint) is the correct answer
