{'answer_start': array([158]), 'answer_text': array(['late 8th century'], dtype=object)}
Lynne Truss attributes an early form of the modern question mark in western language to Alcuin of
 York.[2] Truss describes the punctus interrogativus of the late 8th century as, "a lightning flash, striking from right to left".[3] (The punctuation system of Aelius Donatus, current through the Early Middle Ages, used only simple dots at various heights.)
