You are an anthropologist analyzing bone remains from the grave of an ancient female human. within one of the bones, you find an unusually high concentration of collagen. what does this suggest about the ancient female? a she broke a bone and then died before it was fully healed. b she broke a bone and then died a few hours later. c she broke a bone at a very young age, but it fully healed. d she broke a bone at a very young age, but it did not fully heal.

C. she broke a bone at a very young age, but it did fully heal. 

You can come to this conclusion because collagen helps strengthen bones, to put it simply. Degeneration of collagen typically leads to Osteoporosis and Rheumatoid Arthritis. So less collagen would suggest that a bone had been broken, but was unable to correct itself, leaving the bone more likely to be broken in the future. However, high concentrations of collagen improve ductility, which helps strengthen bones and give them more support and makes them less likely to break. So when you discover remains that had a high level of collagen, you should be able to infer that the individual HAD broken a bone, but it had fully healed, and the extra collagen that was used to mend the break, stuck around afterwards.
