Teacher:In this task, you are given a question and a context passage. You have to answer the question based on the given passage.
Teacher: Now, understand the problem? Solve this instance: Which of the following is not an ancient language: Proto-Celtic, Galicia or Proto-Indo-European?, Context: Although the etymology of the name has been studied since the 7th century by authors like Isidore of Seville —who wrote that "Galicians are called so, because of their fair skin, as the Gauls", relating the name to the Greek word for milk—, currently scholars derive the name of the ancient Callaeci either from Proto-Indo-European *kal-n-eH2 'hill', through a local relational suffix -aik-, so meaning 'the hill (people)'; or either from Proto-Celtic *kallī- 'forest', so meaning 'the forest (people)'. In any case, Galicia, being per se a derivation of the ethnic name Kallaikói, would mean 'the land of the Galicians'.
Student:
Galicia
