 ## Dataset Quality
 For all selected languages, data annotation is performed exclusively by native speakers for whom the language is their first language, in order to ensure high linguistic fidelity, culturally appropriate interpretation and reliable construction of questions and distractors. Consequently, a two-stage quality control process was conducted involving random sampling and cross-checking, producing a final dataset with an inter-annotator agreement of 95.5%, together with verified and consistent gold labels.
