Problem: Time:

Time travel is the concept of moving backwards or forwards to different points in time, in a manner analogous to moving through space, and different from the normal "flow" of time to an earthbound observer. In this view, all points in time (including future times) "persist" in some way. Time travel has been a plot device in fiction since the 19th century. Traveling backwards in time has never been verified, presents many theoretic problems, and may be an impossibility. Any technological device, whether fictional or hypothetical, that is used to achieve time travel is known as a time machine.

Traveling which direction in time has never been verified and presents many problems?
---
A: backwards


Problem: Historically, in North America, one of the most economically destructive pests in cotton production has been the boll weevil. Due to the US Department of Agriculture's highly successful Boll Weevil Eradication Program (BWEP), this pest has been eliminated from cotton in most of the United States. This program, along with the introduction of genetically engineered Bt cotton (which contains a bacterial gene that codes for a plant-produced protein that is toxic to a number of pests such as cotton bollworm and pink bollworm), has allowed a reduction in the use of synthetic insecticides.
On what does the use of Bt cotton reduce reliance?
---
Answer: synthetic insecticides.


Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
In 1904, a British expedition to Tibet, spurred in part by a fear that Russia was extending its power into Tibet as part of The Great Game, invaded the country, hoping that negotiations with the 13th Dalai Lama would be more effective than with Chinese representatives. When the British-led invasion reached Tibet on December 12, 1903, an armed confrontation with the ethnic Tibetans resulted in the Massacre of Chumik Shenko, which resulted in 600 fatalities amongst the Tibetan forces, compared to only 12 on the British side. Afterwards, in 1904 Francis Younghusband imposed a treaty known as the Treaty of Lhasa, which was subsequently repudiated and was succeeded by a 1906 treaty signed between Britain and China.
Who invaded Tibet in 1940?
A: unanswerable


Context and question: More complex inflection is still found in certain lexicalized expressions like de heer des huizes (literally, the man of the house), etc. These are usually remnants of cases (in this instance, the genitive case which is still used in German, cf. Der Herr des Hauses) and other inflections no longer in general use today. In such lexicalized expressions remnants of strong and weak nouns can be found too, e.g. in het jaar des Heren (Anno Domini), where "-en" is actually the genitive ending of the weak noun. Also in this case, German retains this feature. Though the genitive is widely avoided in speech.
How would you say "the man of the house" in Dutch?
Answer: de heer des huizes


Question: The Qing dynasty (1644–1911) was founded after the fall of the Ming, the last Han Chinese dynasty, by the Manchus. The Manchus were formerly known as the Jurchens. When Beijing was captured by Li Zicheng's peasant rebels in 1644, the Chongzhen Emperor, the last Ming emperor, committed suicide. The Manchus then allied with former Ming general Wu Sangui and seized control of Beijing, which became the new capital of the Qing dynasty. The Mancus adopted the Confucian norms of traditional Chinese government in their rule of China proper. Schoppa, the editor of The Columbia Guide to Modern Chinese History argues, "A date around 1780 as the beginning of modern China is thus closer to what we know today as historical 'reality'. It also allows us to have a better baseline to understand the precipitous decline of the Chinese polity in the nineteenth and twentieth centuries."
Is there an answer to this question: What was founded after the fall of the Ming?

Answer: The Qing dynasty


Problem: Protestantism:

The necessity and inerrancy were well-established ideas, garnering little criticism, though they later came under debate from outside during the Enlightenment. The most contentious idea at the time though was the notion that anyone could simply pick up the Bible and learn enough to gain salvation. Though the reformers were concerned with ecclesiology (the doctrine of how the church as a body works), they had a different understanding of the process in which truths in scripture were applied to life of believers, compared to the Catholics' idea that certain people within the church, or ideas that were old enough, had a special status in giving understanding of the text.

What is the term for how the church as a whole works?
---
A:
ecclesiology
