Triple

Target class: two-stage-to-orbit launch vehicle
Context triple: [Starship (SpaceX), instanceOf, two-stage-to-orbit launch vehicle]

• A. orbital launch vehicle
  An orbital launch vehicle is a rocket-powered system designed to transport payloads from Earth's surface into orbit by achieving sufficient velocity and altitude to remain in continuous free-fall around the planet.
• B. two-stage rocket chosen
  A two-stage rocket is a launch vehicle composed of two stacked propulsion segments that ignite sequentially, with the first stage typically discarded after burnout to allow the second stage to continue accelerating the payload more efficiently into space.
• C. orbital launch vehicle first stage
  The orbital launch vehicle first stage is the initial propulsion segment of a rocket that provides the primary thrust to lift the vehicle off the ground and accelerate it through the lower atmosphere before separating for subsequent stages to continue to orbit.
• D. expendable launch vehicle stage
  An expendable launch vehicle stage is a non-reusable rocket segment that houses propulsion, propellant, and associated systems, designed to operate for a specific phase of flight and then be discarded once its fuel is depleted.
• E. proposed launch vehicle
  A proposed launch vehicle is a conceptual or preliminary design for a rocket system intended to transport payloads from Earth’s surface into space, but not yet built or operational.
• F. None of above.
