Answer to Question 1

ANS: D
Particles in the 5- to 10-m range tend to become deposited in the oropharynx and hypopharynx, especially with the turbulence created by the transition of air as it passes around the tongue and into the larynx.

Answer to Question 2

ANS: A
The greater the mass and velocity of a moving object, the greater is its inertia and the greater is the tendency of that object to continue moving along its set path (Figure 39-1).
