The war did not terminate until the fifth year of Aahmes' reign. Its result was the complete defeat of the invading hordes which
had held Lower and Middle Egypt for so long, and their expulsion from Egypt with such ignominy and loss that they made no effort to retaliate or to recover themselves.... It is thought that these captives were so numerous as to become an important element in the population of the eastern Delta, and even to modify the character of the Egyptian race in that quarter. --George Rawlinson, How the Hyksos were Expelled from Egypt, 1881 Because this description of Egyptian history was written by a non-participant, it would be considered an example of A) a biased source. B) a primary source. Eliminate C) a tertiary source. D) a secondary source.
A secondary source is any source of getting information or without the author participating in the scenes described in the text. The author may or may not be taking or writing based on his research in writing the book which can be a result of interpreting, evaluating, and analyzation of the scene described. Secondary sources can be academic/ scholarly books, articles, and commentaries, etc.
George Rawlinson's "How the Hyksos were expelled from Egypt" is a secondary source for it describes a scene that is from the past but which he is not a participant of. He is just interpreting, analyzing, and evaluating the event and then writing about it.
The meat grinder in the Korean war was actually a strategy that they used. There were stills combats that were being deployed to the war to fight. And most of the attacks are initiated by one or single combat unit. The attack strength is on the lower left while the defense is on the lower right.
