user: input question: Given the following passage  "As the number and size of agricultural societies increased, they expanded into lands traditionally used by hunter-gatherers. This process of agriculture-driven expansion led to the development of the first forms of government in agricultural centers, such as the Fertile Crescent, Ancient India, Ancient China, Olmec, Sub-Saharan Africa and Norte Chico.",  answer the following question.

Given the following passage  "Alternatively, or in addition to this practice, the members of an upper house may be indirectly elected by the government or legislature of the component states, as occurred in the United States prior to 1913, or be actual members or delegates of the state governments, as, for example, is the case in the German Bundesrat and in the Council of the European Union. The lower house of a federal legislature is usually directly elected, with apportionment in proportion to population, although states may sometimes still be guaranteed a certain minimum number of seats.",  answer the following question. Note that the answer is present within the text.  Question: What is another way upper house members may be elected?
----
Answer: be actual members or delegates of the state governments
Q: Given the following passage  "There is a variety of annual events, beginning with the relatively new New Year's Day Parade, fireworks display at the London Eye, the world's second largest street party, the Notting Hill Carnival is held during the late August Bank Holiday each year. Traditional parades include November's Lord Mayor's Show, a centuries-old event celebrating the annual appointment of a new Lord Mayor of the City of London with a procession along the streets of the City, and June's Trooping the Colour, a formal military pageant performed by regiments of the Commonwealth and British armies to celebrate the Queen's Official Birthday.",  answer the following question. Note that the answer is present within the text.  Question: What holiday is during late August?
A: Bank Holiday
Question: Given the following passage  "Under mounting political pressure, John finally negotiated terms for a reconciliation, and the papal terms for submission were accepted in the presence of the papal legate Pandulf Verraccio in May 1213 at the Templar Church at Dover. As part of the deal, John offered to surrender the Kingdom of England to the papacy for a feudal service of 1,000 marks (equivalent to £666 at the time) annually: 700 marks (£466) for England and 300 marks (£200) for Ireland, as well as recompensing the church for revenue lost during the crisis. The agreement was formalised in the Bulla Aurea, or Golden Bull. This resolution produced mixed responses. Although some chroniclers felt that John had been humiliated by the sequence of events, there was little public reaction. Innocent benefited from the resolution of his long-standing English problem, but John probably gained more, as Innocent became a firm supporter of John for the rest of his reign, backing him in both domestic and continental policy issues. Innocent immediately turned against Philip, calling upon him to reject plans to invade England and to sue for peace. John paid some of the compensation money he had promised the church, but he ceased making payments in late 1214, leaving two-thirds of the sum unpaid; Innocent appears to have conveniently forgotten this debt for the good of the wider relationship.",  answer the following question. Note that the answer is present within the text.  Question: What was the value in pounds John offered per year?
Answer: 666
[Q]: Given the following passage  "The official policy of the U.S. Government is that Thailand was not an ally of the Axis, and that the United States was not at war with Thailand. The policy of the U.S. Government ever since 1945 has been to treat Thailand not as a former enemy, but rather as a country which had been forced into certain actions by Japanese blackmail, before being occupied by Japanese troops. Thailand has been treated by the United States in the same way as such other Axis-occupied countries as Belgium, Czechoslovakia, Denmark, Greece, Norway, Poland, and the Netherlands.",  answer the following question. Note that the answer is present within the text.  Question: Like the Netherlands, Thailand was treated?
****
[A]: in the same way as such other Axis-occupied countries
Problem: Given the question: Given the following passage  "There has, however, been interest among railroad operators in returning to DC use at higher voltages than previously used. At the same voltage, DC often has less loss than AC, and for this reason high-voltage direct current is already used on some bulk power transmission lines. DC avoids the electromagnetic radiation inherent with AC, and on a railway this also reduces interference with signalling and communications and mitigates hypothetical EMF risks. DC also avoids the power factor problems of AC. Of particular interest to railroading is that DC can supply constant power with a single ungrounded wire. Constant power with AC requires three-phase transmission with at least two ungrounded wires. Another important consideration is that mains-frequency 3-phase AC must be carefully planned to avoid unbalanced phase loads. Parts of the system are supplied from different phases on the assumption that the total loads of the 3 phases will even out. At the phase break points between regions supplied from different phases, long insulated supply breaks are required to avoid them being shorted by rolling stock using more than one pantograph at a time. A few railroads have tried 3-phase but its substantial complexity has made single-phase standard practice despite the interruption in power flow that occurs twice every cycle. An experimental 6 kV DC railway was built in the Soviet Union.",  answer the following question. Note that the answer is present within the text.
