What it measures

LogiQA 2.0 reworks [LogiQA](logiqa.md). Items still come from China's civil-service examination materials, now with more questions, professional re-translation, and removal of culturally specific wording such as Chinese idioms. The main protocol is four-option reading comprehension: a passage, a question, and four answers. A second protocol converts each MRC item into premise-hypothesis pairs labelled entailed or not entailed. lm-evaluation-harness's `logiqa2` task scores the English MRC split only.

Task format

MRC: four-option multiple choice; gold `answer` is an integer 0-3. NLI: two-way label entailed / not entailed over major_premise, minor_premise, and conclusion. English and Chinese MRC files are released separately. lm-eval `logiqa2` is zero-shot multiple choice with acc and acc_norm. A second harness task, `logieval`, is a 1-shot generate-until prompt from csitfun/LogiEval, not the paper's MRC loader.
