In this task, you are given a question and a context passage. You have to answer the question based on the given passage.

Question: Sermons are usually conducted in which kind of building?, Context: Early in 1537, Johannes Agricola (1494–1566) – serving at the time as pastor in Luther's birthplace, Eisleben – preached a sermon in which he claimed that God's gospel, not God's moral law (the Ten Commandments), revealed God's wrath to Christians. Based on this sermon and others by Agricola, Luther suspected that Agricola was behind certain anonymous antinomian theses circulating in Wittenberg. These theses asserted that the law is no longer to be taught to Christians but belonged only to city hall. Luther responded to these theses with six series of theses against Agricola and the antinomians, four of which became the basis for disputations between 1538 and 1540. He also responded to these assertions in other writings, such as his 1539 open letter to C. Güttel Against the Antinomians, and his book On the Councils and the Church from the same year.

Answer: Church


Question: What needs consistency?, Context: The simplest valve gears give events of fixed length during the engine cycle and often make the engine rotate in only one direction. Most however have a reversing mechanism which additionally can provide means for saving steam as speed and momentum are gained by gradually "shortening the cutoff" or rather, shortening the admission event; this in turn proportionately lengthens the expansion period. However, as one and the same valve usually controls both steam flows, a short cutoff at admission adversely affects the exhaust and compression periods which should ideally always be kept fairly constant; if the exhaust event is too brief, the totality of the exhaust steam cannot evacuate the cylinder, choking it and giving excessive compression ("kick back").[citation needed]

Answer: exhaust and compression periods


Question: What superhero is the GAU-8 named for?, Context: If current trends continue, missiles will replace gun systems completely in "first line" service.[citation needed] Guns are being increasingly pushed into specialist roles, such as the Dutch Goalkeeper CIWS, which uses the GAU-8 Avenger 30 mm seven-barrel Gatling gun for last ditch anti-missile and anti-aircraft defence. Even this formerly front-line weapon is currently being replaced by new missile systems, such as the RIM-116 Rolling Airframe Missile, which is smaller, faster, and allows for mid-flight course correction (guidance) to ensure a hit. To bridge the gap between guns and missiles, Russia in particular produces the Kashtan CIWS, which uses both guns and missiles for final defence. Two six-barrelled 30 mm Gsh-6-30 Gatling guns and 9M311 surface-to-air missiles provide for its defensive capabilities.

Answer:
Avenger
