Problem: John, King of England:

By the Victorian period in the 19th century historians were more inclined to draw on the judgements of the chroniclers and to focus on John's moral personality. Kate Norgate, for example, argued that John's downfall had been due not to his failure in war or strategy, but due to his "almost superhuman wickedness", whilst James Ramsay blamed John's family background and his cruel personality for his downfall. Historians in the "Whiggish" tradition, focusing on documents such as the Domesday Book and Magna Carta, trace a progressive and universalist course of political and economic development in England over the medieval period. These historians were often inclined to see John's reign, and his signing of Magna Carta in particular, as a positive step in the constitutional development of England, despite the flaws of the king himself. Winston Churchill, for example, argued that "[w]hen the long tally is added, it will be seen that the British nation and the English-speaking world owe far more to the vices of John than to the labours of virtuous sovereigns".

What documents trace a progressive and universalist course of political and economic development in England?
---
A: Domesday Book and Magna Carta


Problem: There are 366 railway stations in the London Travelcard Zones on an extensive above-ground suburban railway network. South London, particularly, has a high concentration of railways as it has fewer Underground lines. Most rail lines terminate around the centre of London, running into eighteen terminal stations, with the exception of the Thameslink trains connecting Bedford in the north and Brighton in the south via Luton and Gatwick airports. London has Britain's busiest station by number of passengers – Waterloo, with over 184 million people using the interchange station complex (which includes Waterloo East station) each year. Clapham Junction is the busiest station in Europe by the number of trains passing.
How many railway stations are utilized by London's railway network?

Answer: 366


Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Tracks of the Northern Pacific Railroad (NPR) reached Montana from the west in 1881 and from the east in 1882. However, the railroad played a major role in sparking tensions with Native American tribes in the 1870s. Jay Cooke, the NPR president launched major surveys into the Yellowstone valley in 1871, 1872 and 1873 which were challenged forcefully by the Sioux under chief Sitting Bull. These clashes, in part, contributed to the Panic of 1873 which delayed construction of the railroad into Montana. Surveys in 1874, 1875 and 1876 helped spark the Great Sioux War of 1876. The transcontinental NPR was completed on September 8, 1883, at Gold Creek.
When did the Northern Pacific Railroad reach Montana from the east?
A: 1882


Context and question: Asthma is the result of chronic inflammation of the conducting zone of the airways (most especially the bronchi and bronchioles), which subsequently results in increased contractability of the surrounding smooth muscles. This among other factors leads to bouts of narrowing of the airway and the classic symptoms of wheezing. The narrowing is typically reversible with or without treatment. Occasionally the airways themselves change. Typical changes in the airways include an increase in eosinophils and thickening of the lamina reticularis. Chronically the airways' smooth muscle may increase in size along with an increase in the numbers of mucous glands. Other cell types involved include: T lymphocytes, macrophages, and neutrophils. There may also be involvement of other components of the immune system including: cytokines, chemokines, histamine, and leukotrienes among others.
What part of the airway is especially effected by neutrophils?
Answer: unanswerable


Question: According to archaeologists and anthropologists, the earliest clothing likely consisted of fur, leather, leaves, or grass that were draped, wrapped, or tied around the body. Knowledge of such clothing remains inferential, since clothing materials deteriorate quickly compared to stone, bone, shell and metal artifacts. Archeologists have identified very early sewing needles of bone and ivory from about 30,000 BC, found near Kostenki, Russia in 1988. Dyed flax fibers that could have been used in clothing have been found in a prehistoric cave in the Republic of Georgia that date back to 36,000 BP.
Is there an answer to this question: Where have flax fibers which may have been used in clothing found?

Answer: a prehistoric cave


QUES: The history of the area that now constitutes Himachal Pradesh dates back to the time when the Indus valley civilisation flourished between 2250 and 1750 BCE. Tribes such as the Koilis, Halis, Dagis, Dhaugris, Dasa, Khasas, Kinnars, and Kirats inhabited the region from the prehistoric era. During the Vedic period, several small republics known as "Janapada" existed which were later conquered by the Gupta Empire. After a brief period of supremacy by King Harshavardhana, the region was once again divided into several local powers headed by chieftains, including some Rajput principalities. These kingdoms enjoyed a large degree of independence and were invaded by Delhi Sultanate a number of times. Mahmud Ghaznavi conquered Kangra at the beginning of the 10th century. Timur and Sikander Lodi also marched through the lower hills of the state and captured a number of forts and fought many battles. Several hill states acknowledged Mughal suzerainty and paid regular tribute to the Mughals.

When did Mahmud Ghanznavi conquer Kangara?

10th century
