Phrase: Douglas D-558-1 Skystreak | Statement: [Douglas D-558-2 Skyrocket, predecessor, Douglas D-558-1 Skystreak]

Target entity: Douglas D-558-1 Skystreak
Context triple: [Douglas D-558-2 Skyrocket, predecessor, Douglas D-558-1 Skystreak]

• A. Douglas D-558-1 Skystreak chosen
  The Douglas D-558-1 Skystreak was an experimental U.S. Navy research jet of the late 1940s used to investigate high-subsonic and transonic flight, contributing key data to early supersonic aircraft development.
• B. Douglas D-558-2 Skyrocket
  The Douglas D-558-2 Skyrocket was a U.S. Navy and NACA experimental research aircraft that became one of the first aircraft to exceed Mach 2 in level flight during the early 1950s.
• C. Douglas X-3 Stiletto
  The Douglas X-3 Stiletto was a slender, jet-powered experimental research aircraft of the early 1950s designed to investigate sustained supersonic flight and advanced aerodynamic concepts for future high-speed aircraft.
• 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-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.
• F. None of above.
• G. Unsure - the case is ambiguous/there is not enough information to decide.
