Problem: Elizabeth II:

Following their wedding, the couple leased Windlesham Moor, near Windsor Castle, until 4 July 1949, when they took up residence at Clarence House in London. At various times between 1949 and 1951, the Duke of Edinburgh was stationed in the British Crown Colony of Malta as a serving Royal Navy officer. He and Elizabeth lived intermittently, for several months at a time, in the hamlet of Gwardamanga, at Villa Guardamangia, the rented home of Philip's uncle, Lord Mountbatten. The children remained in Britain.

After 1949 where did Elizabeth live in London?

A: Clarence House

Problem: Strasbourg features a number of prominent parks, of which several are of cultural and historical interest: the Parc de l'Orangerie, laid out as a French garden by Andre le Notre and remodeled as an English garden on behalf of Josephine de Beauharnais, now displaying noteworthy French gardens, a neo-classical castle and a small zoo; the Parc de la Citadelle, built around impressive remains of the 17th-century fortress erected close to the Rhine by Vauban; the Parc de Pourtales, laid out in English style around a baroque castle (heavily restored in the 19th century) that now houses a small three-star hotel, and featuring an open-air museum of international contemporary sculpture. The Jardin botanique de l'Universite de Strasbourg (botanical garden) was created under the German administration next to the Observatory of Strasbourg, built in 1881, and still owns some greenhouses of those times. The Parc des Contades, although the oldest park of the city, was completely remodeled after World War II. The futuristic Parc des Poteries is an example of European park-conception in the late 1990s. The Jardin des deux Rives, spread over Strasbourg and Kehl on both sides of the Rhine opened in 2004 and is the most extended (60-hectare) park of the agglomeration. The most recent park is Parc du Heyritz (8,7 ha), opened in 2014 along a canal facing the hopital civil.
What style of park is the Parc du Heyritz?

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Mobbing can be an interspecies activity: it is common for birds to respond to mobbing calls of a different species. Many birds will show up at the sight of mobbing and watch and call, but not participate. It should also be noted that some species can be on both ends of a mobbing attack. Crows are frequently mobbed by smaller songbirds as they prey on eggs and young from these birds' nests, but these same crows will cooperate with smaller birds to drive away hawks or larger mammalian predators. On occasion, birds will mob animals that pose no threat.
What is one thing hawks do when they see mobbing?
A: unanswerable

Context and question: After the capitulation of Axis forces in North Africa, Eisenhower oversaw the highly successful invasion of Sicily. Once Mussolini, the Italian leader, had fallen in Italy, the Allies switched their attention to the mainland with Operation Avalanche. But while Eisenhower argued with President Roosevelt and British Prime Minister Churchill, who both insisted on unconditional terms of surrender in exchange for helping the Italians, the Germans pursued an aggressive buildup of forces in the country making the job more difficult, by adding 19 divisions and initially outnumbering the Allied forces 2 to 1; nevertheless, the invasion of Italy was highly successful.
What did the Allies invade after they conquered North Africa?
Answer: Sicily

Question: Relatively insensitive film, with a correspondingly lower speed index, requires more exposure to light to produce the same image density as a more sensitive film, and is thus commonly termed a slow film. Highly sensitive films are correspondingly termed fast films. In both digital and film photography, the reduction of exposure corresponding to use of higher sensitivities generally leads to reduced image quality (via coarser film grain or higher image noise of other types). In short, the higher the sensitivity, the grainier the image will be. Ultimately sensitivity is limited by the quantum efficiency of the film or sensor.
Is there an answer to this question: How is digital photography different from film?

Answer: unanswerable

Question: Yale and New Haven are working to build a medical and biotechnology research hub in the city and Greater New Haven region, and are succeeding to some extent.[citation needed] The city, state and Yale together run Science Park, a large site three blocks northwest of Yale's Science Hill campus. This multi-block site, approximately bordered by Mansfield Street, Division Street, and Shelton Avenue, is the former home of Winchester's and Olin Corporation's 45 large-scale factory buildings. Currently, sections of the site are large-scale parking lots or abandoned structures, but there is also a large remodeled and functioning area of buildings (leased primarily by a private developer) with numerous Yale employees, financial service and biotech companies.
Is there an answer to this question: What large site is run by Yale, in conjunction with New Haven and the state, situated three blocks away from Yale's Science hill campus?

Answer:
Science Park
