Problem: Paris:

Between 1853 and 1870, the Emperor Napoleon III and the city's first director of parks and gardens, Jean-Charles Alphand, created the Bois de Boulogne, the Bois de Vincennes, Parc Montsouris and the Parc des Buttes-Chaumont, located at the four points of the compass around the city, as well as many smaller parks, squares and gardens in the Paris' quarters. Since 1977, the city has created 166 new parks, most notably the Parc de la Villette (1987), Parc Andre Citroen (1992), and Parc de Bercy (1997). One of the newest parks, the Promenade des Berges de la Seine (2013), built on a former highway on the Left Bank of the Seine between the Pont de l'Alma and the Musee d'Orsay, has floating gardens and gives a view of the city's landmarks.

What park has floating gardens?

Problem: The kingdom is mentioned in the Periplus of the Erythraean Sea as an important market place for ivory, which was exported throughout the ancient world. Aksum was at the time ruled by Zoskales, who also governed the port of Adulis. The Aksumite rulers facilitated trade by minting their own Aksumite currency. The state also established its hegemony over the declining Kingdom of Kush and regularly entered the politics of the kingdoms on the Arabian peninsula, eventually extending its rule over the region with the conquest of the Himyarite Kingdom.
In what country was the Periplus of the Erythraean Sea written?

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
The island experienced large-scale immigration over the 20th century, especially after the Second World War. Bermuda has a diverse population including both those with relatively deep roots in Bermuda extending back for centuries, and newer communities whose ancestry results from recent immigration, especially from Britain, North America, the West Indies, and the Portuguese Atlantic islands (especially the Azores), although these groups are steadily merging. About 46% of the population identified themselves with Bermudian ancestry in 2010, which was a decrease from the 51% who did so in the 2000 census. Those identifying with British ancestry dropped by 1% to 11% (although those born in Britain remain the largest non-native group at 3,942 persons). The number of people born in Canada declined by 13%. Those who reported West Indian ancestry were 13%. The number of people born in the West Indies actually increased by 538. A significant segment of the population is of Portuguese ancestry (10%), the result of immigration over the past 160 years, of whom 79% have residency status.
What did 51% of the population identify as in 2010?
A: unanswerable

Context and question: In Islam, dogs are viewed as unclean because they are viewed as scavengers. In 2015 city councillor Hasan Kucuk of The Hague called for dog ownership to be made illegal in that city. Islamic activists in Lerida, Spain, lobbied for dogs to be kept out of Muslim neighborhoods, saying their presence violated Muslims' religious freedom. In Britain, police sniffer dogs are carefully used, and are not permitted to contact passengers, only their luggage. They are required to wear leather dog booties when searching mosques or Muslim homes.
What city made owing dogs illegal in 2015?
Answer: The Hague

Question: Calvin Veltman undertook, for the National Center for Education Statistics and for the Hispanic Policy Development Project, the most complete study of English language adoption by Hispanophone immigrants. Mr Veltman's language shift studies document high bilingualism rates and subsequent adoption of English as the preferred language of Hispanics, particularly by the young and the native-born. The complete set of these studies' demographic projections postulates the near-complete assimilation of a given Hispanophone immigrant cohort within two generations. Although his study based itself upon a large 1976 sample from the Bureau of the Census (which has not been repeated), data from the 1990 Census tend to confirm the great Anglicization of the US Hispanic American origin population.
Is there an answer to this question: What was Calvin Veltman' findings?

Answer: high bilingualism rates and subsequent adoption of English as the preferred language of Hispanics, particularly by the young and the native-born.

Question: In Central Africa, Ndembu warriors rub themselves with red paint during celebrations. Since their culture sees the color as a symbol of life and health, sick people are also painted with it. Like most Central African cultures, the Ndembu see red as ambivalent, better than black but not as good as white. In other parts of Africa, however, red is a color of mourning, representing death. Because red bears are associated with death in many parts of Africa, the Red Cross has changed its colors to green and white in parts of the continent.
Is there an answer to this question: What color did the Red Cross change to in Central Africa?

Answer:
unanswerable
