text_A: Ultimately it has been determined that his death was likely the result of the combination of his multiple weakening disorders, a leg fracture, perhaps as the result of a fall, and a severe malarial infection. The placement of the mummy's embalming incision is unique. This, combined with the two levels of resin inside his skull, have led to suggestions that an initial mummification was carried out by an inexperienced embalmer.
text_B: Could an archaeologist reasonably conclude that a master-and-apprentice system had been set up for embalming during this time period if she started to find more mummies (generally of lower social class) that had similar levels of resin?
YES.
