Problem: Crimean War:

The immediate chain of events leading to France and the United Kingdom declaring war on Russia on 27 and 28 March 1854 came from the ambition of the French emperor Napoleon III to restore the grandeur of France. He wanted Catholic support that would come his way if he attacked Eastern Orthodoxy, as sponsored by Russia.:103 The Marquis Charles de La Valette was a zealous Catholic and a leading member of the "clerical party," which demanded French protection of the Roman Catholic rights to the holy places in Palestine. In May 1851, Napoleon appointed La Valette as his ambassador to the Porte (the Ottoman Empire).:7–9 The appointment was made with the intent of forcing the Ottomans to recognise France as the "sovereign authority" over the Christian population.:19 Russia disputed this attempted change in authority. Pointing to two more treaties, one in 1757 and the 1774 Treaty of Küçük Kaynarca, the Ottomans reversed their earlier decision, renouncing the French treaty and insisting that Russia was the protector of the Orthodox Christians in the Ottoman Empire.

Who demanded protection for Roman Catholic rights in sacred places in Palestine?
---
A: Charles de La Valette


Problem: Apart from residences for upper and middle class households, sanitation is insufficient in most residential areas. Private flush toilets are too expensive for virtually all residents in townships due to their water consumption and installation cost. As a result, access to improved sanitation has not increased much since independence: In Namibia's rural areas 13% of the population had more than basic sanitation, up from 8% in 1990. Many of Namibia's inhabitants have to resort to "flying toilets", plastic bags to defecate which after use are flung into the bush. The use of open areas close to residential land to urinate and defecate is very common and has been identified as a major health hazard.
In what African country are private flush toilets reasonably priced?

Dutch is the obligatory medium of instruction in schools in Suriname, even for non-native speakers. A further twenty-four percent of the population speaks Dutch as a second language. Suriname gained its independence from the Netherlands in 1975 and has been an associate member of the Dutch Language Union since 2004. The lingua franca of Suriname, however, is Sranan Tongo, spoken natively by about a fifth of the population.
About what percentage of residents of Suriname speak Dutch?

Context and question: After the incorporation of these states to the United States in the first half of the 19th century, the Spanish language was later reinforced in the country by the acquisition of Puerto Rico in 1898. Later waves of emigration from Mexico, Cuba, El Salvador and elsewhere in Hispanic America to the United States beginning in the second half of the 19th century to the present-day have strengthened the role of the Spanish language in the country. Today, Hispanics are one of the fastest growing demographics in the United States, thus increasing the use and importance of American Spanish in the United States.
Which countries came in major emigrations to the US?
Answer: unanswerable


Question: Brasília is known as a departing point for the practice of unpowered air sports, sports that may be practiced with hang gliding or paragliding wings. Practitioners of such sports reveal that, because of the city's dry weather, the city offers strong thermal winds and great "cloud-streets", which is also the name for a manoeuvre quite appreciated by practitioners.

Question: Close to Richmond Park is Kew Gardens which has the world's largest collection of living plants. In 2003, the gardens were put on the UNESCO list of World Heritage Sites. There are also numerous parks administered by London's borough Councils, including Victoria Park in the East End and Battersea Park in the centre. Some more informal, semi-natural open spaces also exist, including the 320-hectare (790-acre) Hampstead Heath of North London, and Epping Forest, which covers 2,476 hectares (6,118.32 acres) in the east. Both are controlled by the City of London Corporation. Hampstead Heath incorporates Kenwood House, the former stately home and a popular location in the summer months where classical musical concerts are held by the lake, attracting thousands of people every weekend to enjoy the music, scenery and fireworks. Epping Forest is a popular venue for various outdoor activities, including mountain biking, walking, horse riding, golf, angling, and orienteering.
