AI2 ARC: science questions separated by baseline difficulty

Contribution grade

Reasoning benchmarks · Evaluation resource design

Reference score125,000Provisional editorial estimate of this exact contribution; its grade is assessed separately.

What changed

Released grade-school science multiple-choice questions, a supporting sentence corpus and reference systems, separating a Challenge set by joint failure of retrieval and word-association solvers.

Scientific scope

Released grade-school science multiple-choice questions, a supporting sentence corpus and reference systems, separating a Challenge set by joint failure of retrieval and word-association solvers. AI2 Reasoning Challenge is distinct from Chollet's Abstraction and Reasoning Corpus. Challenge membership is operationally baseline-relative, not a proof that no shortcut exists. This record concerns general AI evaluation, not scientific or biomedical discoveries in the questions.

Evidence
