Which event can cause people to stop breathing?

• A. Motion sickness
• B. Choking
• C. High altitude sickness
• D. Allergic reaction

Answer: (B)

Breathing can stop when the airway is blocked. Choking occurs when a foreign object or food lodges in the airway, preventing air from passing to the lungs. If air can’t reach the lungs, oxygen can’t reach the brain and other tissues, leading to loss of breath and collapse if not relieved quickly. Motion sickness causes nausea and dizziness from inner-ear signals, not airway blockage, so it doesn’t stop breathing. High altitude sickness comes from reduced oxygen pressure and tends to cause headaches and shortness of breath over time rather than an abrupt cessation of breathing. An allergic reaction can narrow or swell the airway, but the situation described as stopping breathing most directly points to choking, which requires prompt intervention.
