Target entity: Bell X-1A
Context triple: [Bell X-1B, successorTo, Bell X-1A]
  • A. Bell X-1B
    The Bell X-1B was an advanced variant of the original Bell X-1 rocket-powered research aircraft, used primarily to investigate high-speed aerodynamic heating and stability at transonic and supersonic speeds.
  • B. Bell X-1E
    The Bell X-1E was a late, highly modified variant of the pioneering X-1 rocket research aircraft, used by the U.S. to investigate high-speed transonic and supersonic flight aerodynamics in the 1950s.
  • C. Bell X-1C
    The Bell X-1C was a planned but never completed advanced variant of the Bell X-1 rocket-powered research aircraft, intended for high-speed military weapons testing.
  • D. Bell X-1D
    The Bell X-1D was an experimental rocket-powered research aircraft in the X-1 series, built to extend high-speed flight testing beyond the capabilities of the original Bell X-1.
  • E. Bell X-2
    The Bell X-2 was a rocket-powered experimental research aircraft developed in the 1950s to investigate flight characteristics at extremely high speeds and altitudes, contributing crucial data to early supersonic and space-era aeronautics.
  • F. None of above. chosen
  • G. Unsure - the case is ambiguous/there is not enough information to decide.
