Q: Extract the answer to the question from the following context. Question: What artifact used for astronomy is muhc older than stonehenge? Context: During the Neolithic Era, before the onset of desertification, around 9500 BCE the central Sudan had been a rich environment supporting a large population ranging across what is now barren desert, like the Wadi el-Qa'ab. By the 5th millennium BCE, the people who inhabited what is now called Nubia, were full participants in the "agricultural revolution", living a settled lifestyle with domesticated plants and animals. Saharan rock art of cattle and herdsmen suggests the presence of a cattle cult like those found in Sudan and other pastoral societies in Africa today. Megaliths found at Nabta Playa are overt examples of probably the world's first known archaeoastronomy devices, predating Stonehenge by some 2,000 years. This complexity, as observed at Nabta Playa, and as expressed by different levels of authority within the society there, likely formed the basis for the structure of both the Neolithic society at Nabta and the Old Kingdom of Egypt.
A: Megaliths found at Nabta Playa

Q: Extract the answer to the question from the following context. Question: Where is the Oudregracht located? Context: Another landmark is the old centre and the canal structure in the inner city. The Oudegracht is a curved canal, partly following the ancient main branch of the Rhine. It is lined with the unique wharf-basement structures that create a two-level street along the canals. The inner city has largely retained its Medieval structure, and the moat ringing the old town is largely intact. Because of the role of Utrecht as a fortified city, construction outside the medieval centre and its city walls was restricted until the 19th century. Surrounding the medieval core there is a ring of late 19th- and early 20th-century neighbourhoods, with newer neighbourhoods positioned farther out. The eastern part of Utrecht remains fairly open. The Dutch Water Line, moved east of the city in the early 19th century required open lines of fire, thus prohibiting all permanent constructions until the middle of the 20th century on the east side of the city.
A: the inner city

Q: Extract the answer to the question from the following context. Question: What is the disagreement? Context: Scholars continue to debate whether the U.S. Constitution adopted a particular interpretation of the "rule of law," and if so, which one. For example, John Harrison asserts that the word "law" in the Constitution is simply defined as that which is legally binding, rather than being "defined by formal or substantive criteria," and therefore judges do not have discretion to decide that laws fail to satisfy such unwritten and vague criteria. Law Professor Frederick Mark Gedicks disagrees, writing that Cicero, Augustine, Thomas Aquinas, and the framers of the U.S. Constitution believed that an unjust law was not really a law at all.

Q: Extract the answer to the question from the following context. Question: Which of the following is not a technique to reduce defilements: internal investigation, suffering or analyzing? Context: In Theravāda Buddhism, the cause of human existence and suffering is identified as craving, which carries with it the various defilements. These various defilements are traditionally summed up as greed, hatred and delusion. These are believed deeply rooted afflictions of the mind that create suffering and stress. To be free from suffering and stress, these defilements must be permanently uprooted through internal investigation, analyzing, experiencing, and understanding of the true nature of those defilements by using jhāna, a technique of the Noble Eightfold Path. It then leads the meditator to realize the Four Noble Truths, Enlightenment and Nibbāna. Nibbāna is the ultimate goal of Theravadins.
A:
suffering
