Problem: Given the question: Extract the answer to the question from the following context. Question: What is the term for the study of the names? 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'.

Problem: Given the question: Extract the answer to the question from the following context. Question: What determines the definition of a US treaty? Context: In the United States, the term "treaty" has a different, more restricted legal sense than exists in international law. United States law distinguishes what it calls treaties from executive agreement, congressional-executive agreements, and sole executive agreements. All four classes are equally treaties under international law; they are distinct only from the perspective of internal American law. The distinctions are primarily concerning their method of approval. Whereas treaties require advice and consent by two-thirds of the Senators present, sole executive agreements may be executed by the President acting alone. Some treaties grant the President the authority to fill in the gaps with executive agreements, rather than additional treaties or protocols. And finally, congressional-executive agreements require majority approval by both the House and the Senate, either before or after the treaty is signed by the President.
