Answer to Question 1

Answer: D

Answer to Question 2

Answer: Tissue damage from trauma and infections, especially in the feet, are a frequent threat to people with diabetes. At the same time, nerve damage reduces sensation in the extremities, allowing people with diabetes to be unaware of traumatic or infectious tissue damage until it has progressed. Moreover, high blood glucose damages blood vessels serving the limbs and impairs delivery of nutrients to assist in wound healing; thus, amputations are often necessary.
