Problem: Gothic architecture:

The Houses of Parliament in London by Sir Charles Barry with interiors by a major exponent of the early Gothic Revival, Augustus Welby Pugin, is an example of the Gothic revival style from its earlier period in the second quarter of the 19th century. Examples from the High Victorian Gothic period include George Gilbert Scott's design for the Albert Memorial in London, and William Butterfield's chapel at Keble College, Oxford. From the second half of the 19th century onwards it became more common in Britain for neo-Gothic to be used in the design of non-ecclesiastical and non-governmental buildings types. Gothic details even began to appear in working-class housing schemes subsidised by philanthropy, though given the expense, less frequently than in the design of upper and middle-class housing.

Who designed the chapel at Keble College, Oxford?

A: William Butterfield

Problem: Carnival is celebrated in New York City in Brooklyn. As in the UK, the timing of Carnival split from the Christian calendar and is celebrated on Labor Day Monday, in September. It is called the Labor Day Carnival, West Indian Day Parade or West Indian Day Carnival, and was founded by immigrants from Trinidad. That country has one of the largest Caribbean Carnivals. In the mid twentieth century, West Indians moved the event from the beginning of Lent to the Labor Day weekend. Carnival is one of the largest parades and street festivals in New York, with over one million attending. The parade, which consists of steel bands, floats, elaborate Carnival costumes and sound trucks, proceeds along Brooklyn's Eastern Parkway in the Crown Heights neighborhood.

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
DDT, sprayed on the walls of houses, is an organochlorine that has been used to fight malaria since the 1950s. Recent policy statements by the World Health Organization have given stronger support to this approach. However, DDT and other organochlorine pesticides have been banned in most countries worldwide because of their persistence in the environment and human toxicity. DDT use is not always effective, as resistance to DDT was identified in Africa as early as 1955, and by 1972 nineteen species of mosquito worldwide were resistant to DDT.
What kind of pesticide is DDT?
A: an organochlorine

Context and question: There is a clear trend toward the exclusive use of hangul in day-to-day South Korean society. Hanja are still used to some extent, particularly in newspapers, weddings, place names and calligraphy (although it is nowhere near the extent of kanji use in day-to-day Japanese society). Hanja is also extensively used in situations where ambiguity must be avoided,[citation needed] such as academic papers, high-level corporate reports, government documents, and newspapers; this is due to the large number of homonyms that have resulted from extensive borrowing of Chinese words.
What is considered a location with a high level of ambiguity?
Answer: weddings

Question: After two forays into more serious dramatic films, Spielberg then directed the third Indiana Jones film, 1989's Indiana Jones and the Last Crusade. Once again teaming up with Lucas and Ford, Spielberg also cast actor Sean Connery in a supporting role as Indy's father. The film earned generally positive reviews and was another box office success, becoming the highest grossing film worldwide that year; its total box office receipts even topped those of Tim Burton's much-anticipated film Batman, which had been the bigger hit domestically. Also in 1989, he re-united with actor Richard Dreyfuss for the romantic comedy-drama Always, about a daredevil pilot who extinguishes forest fires. Spielberg's first romantic film, Always was only a moderate success and had mixed reviews.
Is there an answer to this question: When did the second Indiana Jones movie come out?

Answer: unanswerable

Question: Oral rehydration solution (ORS) (a slightly sweetened and salty water) can be used to prevent dehydration. Standard home solutions such as salted rice water, salted yogurt drinks, vegetable and chicken soups with salt can be given. Home solutions such as water in which cereal has been cooked, unsalted soup, green coconut water, weak tea (unsweetened), and unsweetened fresh fruit juices can have from half a teaspoon to full teaspoon of salt (from one-and-a-half to three grams) added per liter. Clean plain water can also be one of several fluids given. There are commercial solutions such as Pedialyte, and relief agencies such as UNICEF widely distribute packets of salts and sugar. A WHO publication for physicians recommends a homemade ORS consisting of one liter water with one teaspoon salt (3 grams) and two tablespoons sugar (18 grams) added (approximately the "taste of tears"). Rehydration Project recommends adding the same amount of sugar but only one-half a teaspoon of salt, stating that this more dilute approach is less risky with very little loss of effectiveness. Both agree that drinks with too much sugar or salt can make dehydration worse.
