        "question": "What are the ground transportation options in Washington D.C.?",
        "answer": "Washington Dulles (IAD) connects to the city center via the Silver Line Metro, which reaches downtown in about an hour and is the most affordable option at around three dollars. The Silver Line Express bus links the airport to the Wiehle-Reston East Metro station in roughly twenty minutes, where you continue by rail. Taxis and ride-share services like Uber and Lyft are widely available and take forty-five to sixty minutes depending on traffic, costing significantly more than transit. Shared shuttle services offer a middle ground in price but require stops at multiple destinations. Car rentals are available at the airport and suit travelers heading beyond the metro area. The Silver Line Metro is increasingly popular since its extension to Dulles opened in 2022, though ride-share remains heavily used for convenience, especially with luggage."
