Answer to Question 1

D
Feedback:
An IRLD converts sound into infrared light and sends it through a wall- or ceiling-mounted receiver to the person wearing the listening device. The light is converted back into an auditory stimulus. IRLDs do not direct sound into one ear, influence the function of the auditory nerve, or increase the volume of foreground noise.

Answer to Question 2

A
Feedback:
The pharynx forms a part of the upper airway. The upper airway consists of the nose and pharynx, which is subdivided into the nasopharynx, oropharynx, and laryngopharynx. The lower airway consists of the trachea, bronchi, bronchioles, and alveoli.
