Input: Consider Input: Passage: Though women were protected by late Sumerian law and were able to achieve a higher status in Sumer than in other contemporary civilizations, the culture was male-dominated. The Code of Ur-Nammu, the oldest such codification yet discovered, dating to the Ur-III "Sumerian Renaissance", reveals a glimpse at societal structure in late Sumerian law. Beneath the lu-gal ("great man" or king), all members of society belonged to one of two basic strata: The "lu" or free person, and the slave (male, arad; female geme). The son of a lu was called a dumu-nita until he married. A woman (munus) went from being a daughter (dumu-mi), to a wife (dam), then if she outlived her husband, a widow (numasu) and she could then remarry. Question: How were women protected in Sumerian society?

Output: law

Input: Consider Input: Passage: Another civil war ensued after the death of Karim Khan in 1779, out of which Aqa Mohammad Khan emerged, founding the Qajar Dynasty in 1794. In 1795, following the disobedience of the Georgian subjects and their alliance with the Russians, the Qajars captured Tblisi by the Battle of Krtsanisi, and drove the Russians out of the entire Caucasus, reestablishing a short-lived Iranian suzerainty over the region. The Russo-Persian wars of 18041813 and 18261828 resulted in large irrevocable territorial losses for Iran in the Caucasus, comprising all of Transcaucasia and Dagestan, which made part of the very concept of Iran for centuries, and thus substantial gains for the neighboring Russian Empire. Question: Whose death in 1779 led to a civil war in Iran?

Output: Karim Khan

Input: Consider Input: Passage: Paper at this point is uncoated. Coated paper has a thin layer of material such as calcium carbonate or china clay applied to one or both sides in order to create a surface more suitable for high-resolution halftone screens. (Uncoated papers are rarely suitable for screens above 150 lpi.) Coated or uncoated papers may have their surfaces polished by calendering. Coated papers are divided into matte, semi-matte or silk, and gloss. Gloss papers give the highest optical density in the printed image. Question: What process is done to polish the surface of the paper?
Output: calendering
