Final answer:
Hildegard of Bingen is the oldest-known female composer with surviving works and wrote treatises on theology, science, and medicine, but did not write the earliest surviving morality play or produce her works at the University of Paris.
Step-by-step explanation:
Hildegard of Bingen was a remarkable figure in the history of music and intellectual thought. The statements about her include several truths: Hildegard wrote the earliest surviving morality play; this is not accurate as Hroswitha is known for devotional writings and morality plays earlier than Hildegard's time. Hildegard produced her musical works at the University of Paris; this is also incorrect, as there is no record of her working at the University of Paris.
However, two correct facts are that Hildegard is the oldest-known female composer whose work still survives to this day and that Hildegard wrote treatises on theology, science, and medicine, reflecting the breadth of her scholarly contributions.
