Phrase: SLAC linac | Statement: [SLC, predecessor, SLAC linac]

Target entity: SLAC linac
Context triple: [SLC, predecessor, SLAC linac]

• A. Fermilab Linac
  Fermilab Linac is a linear accelerator at Fermilab that provides high-energy proton beams for subsequent acceleration stages in the laboratory’s particle physics experiments.
• B. Stanford Linear Collider (SLC)
  The Stanford Linear Collider (SLC) was a pioneering electron–positron linear collider at SLAC that enabled precision studies of the Z boson and electroweak interactions.
• C. SLAC Large Detector
  SLAC Large Detector was a particle physics detector at the Stanford Linear Accelerator Center used primarily for precision studies of Z boson decays in electron-positron collisions.
• D. UNILAC linear accelerator
  The UNILAC linear accelerator is a heavy-ion accelerator at the GSI Helmholtz Centre used to produce and study high-energy ion beams for nuclear and atomic physics research.
• E. Fermilab Main Injector
  The Fermilab Main Injector is a high-energy synchrotron accelerator at Fermilab that boosts proton and antiproton beams for particle physics experiments and other downstream accelerators.
• F. None of above. chosen
• G. Unsure - the case is ambiguous/there is not enough information to decide.

Target entity: SLAC linac
Target entity description: The SLAC linac is a long linear particle accelerator at the SLAC National Accelerator Laboratory, historically used for high-energy physics experiments and as the main accelerator before the construction of the Stanford Linear Collider.
