Problem: Paris:

The southern Essonne department specialises in science and technology, and the south-eastern Val-de-Marne, with its wholesale Rungis food market, specialises in food processing and beverages. The Paris region's manufacturing decline is quickly being replaced by eco-industries: these employ about 100,000 workers. In 2011, while only 56,927 construction workers worked in Paris itself, its metropolitan area employed 246,639, in an activity centred largely around the Seine-Saint-Denis (41,378) and Hauts-de-Seine (37,303) departments and the new business-park centres appearing there.

How many construction workers worked in Paris in 2011?

A: 56,927

Problem: Bowers confronted a similar problem in his edition of Maggie. Crane originally printed the novel privately in 1893. To secure commercial publication in 1896, Crane agreed to remove profanity, but he also made stylistic revisions. Bowers's approach was to preserve the stylistic and literary changes of 1896, but to revert to the 1893 readings where he believed that Crane was fulfilling the publisher's intention rather than his own. There were, however, intermediate cases that could reasonably have been attributed to either intention, and some of Bowers's choices came under fire both as to his judgment, and as to the wisdom of conflating readings from the two different versions of Maggie.
What alterations did Crane make to secure commercial publication?

Answer: remove profanity, but he also made stylistic revisions

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Digestive systems take many forms. There is a fundamental distinction between internal and external digestion. External digestion developed earlier in evolutionary history, and most fungi still rely on it. In this process, enzymes are secreted into the environment surrounding the organism, where they break down an organic material, and some of the products diffuse back to the organism. Animals have a tube (gastrointestinal tract) in which internal digestion occurs, which is more efficient because more of the broken down products can be captured, and the internal chemical environment can be more efficiently controlled.
What is the name of the tube that helps add in animal digestion?
A: gastrointestinal tract

Context and question: The 2nd, 3rd and 4th Canadian Divisions each has a Regular Force brigade group, and each division except the 1st has two to three Reserve Force brigades groups. In total, there are ten Reserve Force brigade groups. The 5th Canadian Division and the 2nd Canadian Division each have two Reserve Force brigade groups, while the 4th Canadian Division and the 3rd Canadian Division each have three Reserve Force brigade groups. Major training and support establishments exist at CFB Gagetown, CFB Montreal and CFB Wainwright.
Where is most of the minor training performed?
Answer: unanswerable

Question: Agriculture is dominated by the cultivation and sale of food crops such as cassava, peanuts, maize, sorghum, millet, sesame, and plantain. The annual real GDP growth rate is just above 3%. The importance of food crops over exported cash crops is indicated by the fact that the total production of cassava, the staple food of most Central Africans, ranges between 200,000 and 300,000 tonnes a year, while the production of cotton, the principal exported cash crop, ranges from 25,000 to 45,000 tonnes a year. Food crops are not exported in large quantities, but still constitute the principal cash crops of the country, because Central Africans derive far more income from the periodic sale of surplus food crops than from exported cash crops such as cotton or coffee.[citation needed] Much of the country is self-sufficient in food crops; however, livestock development is hindered by the presence of the tsetse fly.[citation needed]
Is there an answer to this question: How many tonnes of Cassave is produced per year?

Answer: 200,000 and 300,000

Problem: Space Race:

In May 1972, President Richard M. Nixon and Soviet Premier Leonid Brezhnev negotiated an easing of relations known as detente, creating a temporary "thaw" in the Cold War. In the spirit of good sportsmanship, the time seemed right for cooperation rather than competition, and the notion of a continuing "race" began to subside.

When did President Nixon and Brezhnev of the USSR end the Cold War?

A:
May 1972
