Woodin cardinal

Target entity: Woodin cardinal
Context triple: [Hugh Woodin, notableConcept, Woodin cardinal]

• A. Feferman–Schütte ordinal
  The Feferman–Schütte ordinal is a large countable ordinal that marks the proof-theoretic strength of predicative arithmetic and analysis, serving as a key boundary in ordinal analysis and foundations of mathematics.
• B. Bachmann–Howard ordinal
  The Bachmann–Howard ordinal is a large countable ordinal that serves as a key benchmark in proof theory, marking the strength of powerful formal systems extending predicative arithmetic.
• C. Vaught conjecture
  The Vaught conjecture is an open problem in mathematical logic and model theory that predicts a precise restriction on the possible numbers of countable models of a complete first-order theory.
• D. Kripke–Platek set theory
  Kripke–Platek set theory is a weaker, predicative subsystem of Zermelo–Fraenkel set theory focused on sets that are explicitly constructible and often used in the study of admissible sets and recursion theory.
• E. continuum hypothesis
  The continuum hypothesis is a central conjecture in set theory proposing a specific relationship between the sizes of the set of real numbers and the set of natural numbers, famously shown to be independent of the standard axioms of mathematics.
• F. None of above. chosen
• G. Unsure - the case is ambiguous/there is not enough information to decide.

Target entity: Woodin cardinal
Target entity description: A Woodin cardinal is a large cardinal in set theory with strong consistency and determinacy properties, central to modern research on the foundations of mathematics and descriptive set theory.
