At a glance
What a problem looks like
One question, written to invite a plausible falsehood. Its category, its adversarial type and the source documenting the misconception all narrow the answer, so none of them is published.
How it is scored
The source ships a best answer plus lists of correct and incorrect answers; this catalogue keeps all of them in restricted storage and never renders them.
Metric: truthfulness and informativeness, judged per answer; the multiple-choice configuration reports MC1/MC2 accuracy
Why it is hard
Every question has an answer that sounds right because people repeat it. Scale alone tends to make this worse, because the falsehood is well represented in the training text.
