Problem: Protestantism:

In 1999, the representatives of Lutheran World Federation and Catholic Church signed the Joint Declaration on the Doctrine of Justification, apparently resolving the conflict over the nature of justification which was at the root of the Protestant Reformation, although Confessional Lutherans reject this statement. This is understandable, since there is no compelling authority within them. On 18 July 2006, delegates to the World Methodist Conference voted unanimously to adopt the Joint Declaration.

What document was signed in 1999?
---
A: the Joint Declaration on the Doctrine of Justification


Problem: Although there is some evidence of earlier inhabitation in the region of Utrecht, dating back to the Stone Age (app. 2200 BCE) and settling in the Bronze Age (app. 1800–800 BCE), the founding date of the city is usually related to the construction of a Roman fortification (castellum), probably built in around 50 CE. A series of such fortresses was built after the Roman emperor Claudius decided the empire should not expand north. To consolidate the border the limes Germanicus defense line was constructed  along the main branch of the river Rhine, which at that time flowed through a more northern bed compared to today (what is now the Kromme Rijn). These fortresses were designed to house a cohort of about 500 Roman soldiers. Near the fort settlements would grow housing artisans, traders and soldiers' wives and children.
 What did the Roman emperor Claudius decide

Answer: Claudius decided the empire should not expand north.


Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
The Grands Magasins Dufayel was a huge department store with inexpensive prices built in 1890 in the northern part of Paris, where it reached a very large new customer base in the working class. In a neighborhood with few public spaces, it provided a consumer version of the public square. It educated workers to approach shopping as an exciting social activity not just a routine exercise in obtaining necessities, just as the bourgeoisie did at the famous department stores in the central city. Like the bourgeois stores, it helped transform consumption from a business transaction into a direct relationship between consumer and sought-after goods. Its advertisements promised the opportunity to participate in the newest, most fashionable consumerism at reasonable cost. The latest technology was featured, such as cinemas and exhibits of inventions like X-ray machines (that could be used to fit shoes) and the gramophone.
How were these stores the same as most during that time?
A: unanswerable


Context and question: The most popular Korean dog dish is gaejang-guk (also called bosintang), a spicy stew meant to balance the body's heat during the summer months; followers of the custom claim this is done to ensure good health by balancing one's gi, or vital energy of the body. A 19th century version of gaejang-guk explains that the dish is prepared by boiling dog meat with scallions and chili powder. Variations of the dish contain chicken and bamboo shoots. While the dishes are still popular in Korea with a segment of the population, dog is not as widely consumed as beef, chicken, and pork.
What is dog meat boiled with to create Gaejang-guk?
Answer: scallions and chili powder.


Question: The fiber is most often spun into yarn or thread and used to make a soft, breathable textile. The use of cotton for fabric is known to date to prehistoric times; fragments of cotton fabric dated from 5000 BC have been excavated in Mexico and the Indus Valley Civilization in Ancient India (modern-day Pakistan and some parts of India). Although cultivated since antiquity, it was the invention of the cotton gin that lowered the cost of production that led to its widespread use, and it is the most widely used natural fiber cloth in clothing today.
Is there an answer to this question: Where in India has the cotton gin been found from prehistoric times?

Answer: unanswerable


Panama's first department stores such as Bazaar Francés, La Dalia and La Villa de Paris started as textile retailers at the turn of the nineteenth century. Later on in the twentieth century these eventually gave way to stores such as Felix B. Maduro, Sarah Panamá, Figali, Danté, Sears, Gran Morrison and smaller ones such as Bon Bini, Cocos, El Lider, Piccolo and Clubman among others. Of these only Felix B. Maduro (usually referred to as Felix by locals) and Danté remain strong. All the others have either folded or declined although Cocos has managed to secure a good position in the market.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): When did Panama's Department stores first start? 
Ah, so..
at the turn of the nineteenth century
