Input: Read this: From the early 16th century, both Western Armenia and Eastern Armenia fell under Iranian Safavid rule. Owing to the century long Turco-Iranian geo-political rivalry that would last in Western Asia, significant parts of the region were frequently fought over between the two rivalling empires. From the mid 16th century with the Peace of Amasya, and decisively from the first half of the 17th century with the Treaty of Zuhab until the first half of the 19th century, Eastern Armenia was ruled by the successive Iranian Safavid, Afsharid and Qajar empires, while Western Armenia remained under Ottoman rule. In the late 1820s, the parts of historic Armenia under Iranian control centering on Yerevan and Lake Sevan (all of Eastern Armenia) were incorporated into the Russian Empire following Iran's forced ceding of the territories after its loss in the Russo-Persian War (1826-1828) and the outcoming Treaty of Turkmenchay. Western Armenia however, remained in Ottoman hands.
Question: What year did the Safavid-Qajar war end?

QUES: Liberia's highest judicial authority is the Supreme Court, made up of five members and headed by the Chief Justice of Liberia. Members are nominated to the court by the president and are confirmed by the Senate, serving until the age of 70. The judiciary is further divided into circuit and speciality courts, magistrate courts and justices of the peace. The judicial system is a blend of common law, based on Anglo-American law, and customary law. An informal system of traditional courts still exists within the rural areas of the country, with trial by ordeal remaining common despite being officially outlawed.

QUES: The Church of the Holy Apostles in Thessaloniki was built in 1310–14. Although some vandal systematically removed the gold tesserae of the background it can be seen that the Pantokrator and the prophets in the dome follow the traditional Byzantine pattern. Many details are similar to the Pammakaristos mosaics so it is supposed that the same team of mosaicists worked in both buildings. Another building with a related mosaic decoration is the Theotokos Paregoritissa Church in Arta. The church was established by the Despot of Epirus in 1294–96. In the dome is the traditional stern Pantokrator, with prophets and cherubim below.
When was the Church of the Holy Apostles built? 

ANS: 1310–14


The first amniotes apparently arose in the Late Carboniferous. They descended from earlier reptiliomorph amphibious tetrapods, which lived on land that was already inhabited by insects and other invertebrates as well as by ferns, mosses and other plants. Within a few million years, two important amniote lineages became distinct: the synapsids, which would later include the common ancestor of the mammals; and the sauropsids, which would eventually come to include turtles, lizards, snakes, crocodilians, dinosaurs and birds. Synapsids have a single hole (temporal fenestra) low on each side of the skull.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): From which period did the first known amniotes arise from?
Ah, so.. Carboniferous


Question: In 1994, responding to the need for a more useful system for describing chronic pain, the International Association for the Study of Pain (IASP) classified pain according to specific characteristics: (1) region of the body involved (e.g. abdomen, lower limbs), (2) system whose dysfunction may be causing the pain (e.g., nervous, gastrointestinal), (3) duration and pattern of occurrence, (4) intensity and time since onset, and (5) etiology. However, this system has been criticized by Clifford J. Woolf and others as inadequate for guiding research and treatment. Woolf suggests three classes of pain : (1) nociceptive pain, (2) inflammatory pain which is associated with tissue damage and the infiltration of immune cells, and (3) pathological pain which is a disease state caused by damage to the nervous system or by its abnormal function (e.g. fibromyalgia, irritable bowel syndrome, tension type headache, etc.).
Try to answer this question if possible: How many classes of pain does J. Woolf Clifford suggest?
Answer: unanswerable


Input: Read this: Religious Jews have Minhagim, customs, in addition to Halakha, or religious law, and different interpretations of law. Different groups of religious Jews in different geographic areas historically adopted different customs and interpretations. On certain issues, Orthodox Jews are required to follow the customs of their ancestors, and do not believe they have the option of picking and choosing. For this reason, observant Jews at times find it important for religious reasons to ascertain who their household's religious ancestors are in order to know what customs their household should follow. These times include, for example, when two Jews of different ethnic background marry, when a non-Jew converts to Judaism and determines what customs to follow for the first time, or when a lapsed or less observant Jew returns to traditional Judaism and must determine what was done in his or her family's past. In this sense, "Ashkenazic" refers both to a family ancestry and to a body of customs binding on Jews of that ancestry. Reform Judaism, which does not necessarily follow those minhagim, did nonetheless originate among Ashkenazi Jews.
Question: For religious Jews, what does Minhagim mean?

Output:
customs
