Input: Read this: Baptists have faced many controversies in their 400-year history, controversies of the level of crises. Baptist historian Walter Shurden says the word "crisis" comes from the Greek word meaning "to decide." Shurden writes that contrary to the presumed negative view of crises, some controversies that reach a crisis level may actually be "positive and highly productive." He claims that even schism, though never ideal, has often produced positive results. In his opinion crises among Baptists each have become decision-moments that shaped their future. Some controversies that have shaped Baptists include the "missions crisis", the "slavery crisis", the "landmark crisis", and the "modernist crisis".
Question: Who wrote that some controversies reach a crisis level may actually be "positive and highly productive?"

Output: Walter Shurden


QUES: In Northern Germany, Netherlands, northern Poland, Denmark, and the Baltic countries local building stone was unavailable but there was a strong tradition of building in brick. The resultant style, Brick Gothic, is called "Backsteingotik" in Germany and Scandinavia and is associated with the Hanseatic League. In Italy, stone was used for fortifications, but brick was preferred for other buildings. Because of the extensive and varied deposits of marble, many buildings were faced in marble, or were left with undecorated façade so that this might be achieved at a later date.

Why were many buildings covered with marbles?
What is the answer?
ANS: unanswerable


QUES: Winston Churchill, on forming his government in 1940, created the office of Minister of Defence to exercise ministerial control over the Chiefs of Staff Committee and to co-ordinate defence matters. The post was held by the Prime Minister of the day until Clement Attlee's government introduced the Ministry of Defence Act of 1946. The new ministry was headed by a Minister of Defence who possessed a seat in the Cabinet. The three existing service Ministers—the Secretary of State for War, the First Lord of the Admiralty, and the Secretary of State for Air—remained in direct operational control of their respective services, but ceased to attend Cabinet.
When was the Ministry of Defence Act introduced?

ANS: 1946


College sports are also popular in North Carolina, with 18 schools competing at the Division I level. The Atlantic Coast Conference (ACC) is headquartered in Greensboro, and both the ACC Football Championship Game (Charlotte) and the ACC Men's Basketball Tournament (Greensboro) were most recently held in North Carolina. College basketball in particular is very popular, buoyed by the Tobacco Road rivalries between Duke, North Carolina, North Carolina State, and Wake Forest. The ACC Championship Game and The Belk Bowl are held annually in Charlotte's Bank of America Stadium, featuring teams from the ACC and the Southeastern Conference. Additionally, the state has hosted the NCAA Men's Basketball Final Four on two occasions, in Greensboro in 1974 and in Charlotte in 1994.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): How many times has North Carolina hosted the NCAA final four?
Ah, so.. two


Question: A significant portion of historical writing ranks as literature, particularly the genre known as creative nonfiction, as can a great deal of journalism, such as literary journalism. However, these areas have become extremely large, and often have a primarily utilitarian purpose: to record data or convey immediate information. As a result, the writing in these fields often lacks a literary quality, although it often(and in its better moments)has that quality. Major "literary" historians include Herodotus, Thucydides and Procopius, all of whom count as canonical literary figures.
Try to answer this question if possible: Who are some classic historians regarded as literary historians?
Answer: Herodotus, Thucydides and Procopius


QUES: Many of the limitations of the classic commutator DC motor are due to the need for brushes to press against the commutator. This creates friction. Sparks are created by the brushes making and breaking circuits through the rotor coils as the brushes cross the insulating gaps between commutator sections. Depending on the commutator design, this may include the brushes shorting together adjacent sections – and hence coil ends – momentarily while crossing the gaps. Furthermore, the inductance of the rotor coils causes the voltage across each to rise when its circuit is opened, increasing the sparking of the brushes. This sparking limits the maximum speed of the machine, as too-rapid sparking will overheat, erode, or even melt the commutator. The current density per unit area of the brushes, in combination with their resistivity, limits the output of the motor. The making and breaking of electric contact also generates electrical noise; sparking generates RFI. Brushes eventually wear out and require replacement, and the commutator itself is subject to wear and maintenance (on larger motors) or replacement (on small motors). The commutator assembly on a large motor is a costly element, requiring precision assembly of many parts. On small motors, the commutator is usually permanently integrated into the rotor, so replacing it usually requires replacing the whole rotor.
What do brushes need to be in contact with?

ANS:
commutator
