Answer to Question 1

D
It is work efficiency (calories consumed) rather than ventilatory efficiency that determines a person's breathing pattern. Muscle efficiency and heart function do not affect breathing pattern.

Answer to Question 2

C
The autoimmune disorder found with Guillain-Barr syndrome results in the removal of the myelin sheath from around the peripheral nerve.
