Final Answer:
Sergio flew from O'Hare International Airport to New York. Final answer is Option 1: O'Hare International Airport.
Step-by-step explanation:
Sergio's departure from O'Hare International Airport is the most likely scenario due to O'Hare being a major international hub in Chicago, serving as a primary departure point for many flights. Additionally, O'Hare is known for its extensive domestic and international connections, making it a probable choice for a flight to New York.
LaGuardia Airport and John F. Kennedy International Airport are both located in New York, so they are not departure points from Chicago. Midway International Airport primarily handles domestic flights, and while it's a significant airport in Chicago, O'Hare is generally the preferred choice for long-distance or international travel.
In conclusion, considering the prominence of O'Hare International Airport in Chicago and its role as a major travel hub, it is the most plausible departure point for Sergio's flight to New York. Final answer is Option 1: O'Hare International Airport.
