the blood has high co levels.
the body tissues have low oxygen levels.
the body tissues lack oxygen.

Explanation:

First Question (Diagnostic Test for Sleep Problems)

• Bronchoscopy: Examines the bronchi (airways), not related to sleep problems.
• Sputum cytology: Analyzes sputum for cells (e.g., cancer), not for sleep.
• Laryngoscopy: Examines the larynx (voice box), not related to sleep.
• Polysomnography: A test used to diagnose sleep disorders by monitoring various physiological parameters during sleep. So this is the correct test for sleep problems.

• Anoxia refers to a total lack of oxygen supply to body tissues.
• "The blood has low oxygen levels" describes hypoxemia (low blood oxygen), not anoxia.
• "The blood has high CO levels" is related to carbon monoxide poisoning, not anoxia.
• "The body tissues have low oxygen levels" is hypoxia (low tissue oxygen), while anoxia is a complete lack. The option "The body tissues lack oxygen" accurately defines anoxia.

Answer:

D. Polysomnography
