If a passenger suddenly experiences acute chest pain, difficulty breathing, or collapses unconscious (suspected heart attack or stroke) inside the taxi, what is the driver's most effective emergency response?

1. Immediately dial 120 emergency medical services, navigate safely to the nearest hospital emergency department, ensure the passenger's airway remains clear, and notify the company dispatch
2. Force the unconscious passenger to drink a cup of boiling water and eat solid snacks
3. Shake the passenger vigorously and pull them out onto the roadway sidewalk
4. Continue regular scheduled routes and ignore the passenger
