Example Input: The Chancellor is the third-oldest major state office in English and British history; it originally carried responsibility for the Exchequer, the medieval English institution for the collection and auditing of royal revenues which dates from the Anglo-Saxon period and survived the Norman conquest of England. The earliest surviving records which are the results of the exchequer's audit, date from 1129 -- 30 under King Henry I and show continuity from previous years. The Chancellor controlled monetary policy as well as fiscal policy until 1997, when the Bank of England was granted independent control of its interest rates. The Chancellor also has oversight of public spending across Government departments.

Example Input: Oedipus Rex, also known by its Greek title, Oedipus Tyrannus (Ancient Greek: Οἰδίπους Τύραννος IPA: (oidípuːs týranːos)), or Oedipus the King, is an Athenian tragedy by Sophocles that was first performed around 429 BC. Originally, to the ancient Greeks, the title was simply Oedipus (Οἰδίπους), as it is referred to by Aristotle in the Poetics. It is thought to have been renamed Oedipus Tyrannus to distinguish it from another of Sophocles' plays, Oedipus at Colonus. In antiquity, the term 'tyrant' referred to a ruler, but it did not necessarily have a negative connotation.
Example Output: difference between oedipus the king and oedipus rex
