choices.text: beijing:new york:capital river:Mississippi river:Hudson river undergraduate:graduate:student civil law:constitution:mother law
explanation: both "gold" and "platinum" are "metals", but in addition to "gold" and "platinum" there is iron and so on. "beijing" is the "capital", but "new york" is not the "capital". "MIssissippl river" and "Hudson river" are both "river", but the word order is inconsistent with the query. "undergraduate" and "graduate" are both "students", but in addition to "undergraduate" and "graduate" there are elementary school students, etc. law includes "civil law" and "constitution", but "civil law" is not a kind of "mother law", "constitution" is also called "mother law".
