Now we can apply our observations to considering how this mountain range was built. Review the statements below, and select the best answer regarding the geologic history of mountain building forces in the Canadian Rockies.

A:Compressional deformation dominates the Canadian Rockies at the regional scale.

B:We have examined a brittle deformation feature at Mt. Kidd in the Canadian Rockies.

C:Rock folding, like at Mt. Kidd, is not a result of compressional mountain building.

D:Tensional stress formed the paired anticline-syncline at Mt. Kidd.

The correct answer is

A:Compressional deformation dominates the Canadian Rockies at the regional scale.

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.
