The first one is hyperbole.
Explanation:
Diabetes mellitus results from a deficiency in the amount of insulin released from the pancreas in response to glucose (type I) or from a decrease in the ability of muscle and fat cells to respond to insulin (type II). In both types, the regulation of blood glucose is impaired, leading to persistent hyperglycemia and numerous other possible complications in untreated patients such as tissue damage, raises the risk of heart-attack, kidney disease and vision deterioration. Type I diabetes is caused by an autoimmune process that destroys the insulin-producing B cells in the pancreas. Also called insulin-dependent diabetes, this form of the disease is generally responsive to insulin therapy. Most Americans with diabetes mellitus have type II, but the underlying cause of this form of the disease is not well understood.
There was two of the same question, but here is the answer again with a little more depth.
D - spine alignment and foot size.
It was only the late Australopiths that had an S-shaped spine. This allowed for them to be bipedal, that is, the ability to walk on two legs as we do. This is because the S-shaped spine allowed them to balance when they were standing. The late Australopiths also have shorter and less flexible toes. These smaller, but sturdier feet made pushing off the ground much easier - aiding in their bipedalism.
The ear cavity (which is affected in infectious otitis) is connected by a duct (the Eustachian tube) to the nasopharynx located behind the nasal fossae.
Otitis is related to a bacterial or viral infection, which most often contaminating the middle ear as a result of rhino-sinusitis or rhino-pharyngitis by borrowing the Eustachian tube or vice versa (otitis media evolving towards a pharyngitis).
