Problem: Widowed in 1861, the grief-stricken Queen withdrew from public life and left Buckingham Palace to live at Windsor Castle, Balmoral Castle and Osborne House. For many years the palace was seldom used, even neglected. In 1864, a note was found pinned to the fence of Buckingham Palace, saying: "These commanding premises to be let or sold, in consequence of the late occupant's declining business." Eventually, public opinion forced the Queen to return to London, though even then she preferred to live elsewhere whenever possible. Court functions were still held at Windsor Castle, presided over by the sombre Queen habitually dressed in mourning black, while Buckingham Palace remained shuttered for most of the year.
When year did Prince Albert die?
The answer is the following: 1861

Complex serological techniques have been developed into what are known as Immunoassays. Immunoassays can use the basic antibody antigen binding as the basis to produce an electro - magnetic or particle radiation signal, which can be detected by some form of instrumentation. Signal of unknowns can be compared to that of standards allowing quantitation of the target antigen. To aid in the diagnosis of infectious diseases, immunoassays can detect or measure antigens from either infectious agents or proteins generated by an infected organism in response to a foreign agent. For example, immunoassay A may detect the presence of a surface protein from a virus particle. Immunoassay B on the other hand may detect or measure antibodies produced by an organism's immune system that are made to neutralize and allow the destruction of the virus.
What type of signal do immunoassays produce?
electro - magnetic or particle radiation

Input: Article: Bermuda has developed a proud Rugby Union community. The Bermuda Rugby Union team won the 2011 Caribbean championships, defeating Guyana in the final. They previously beat The Bahamas and Mexico to take the crown. Rugby 7's is also played, with four rounds scheduled to take place in the 20112012 season. The Bermuda 7's team competed in the 2011 Las Vegas 7's, defeating the Mexican team. There are four clubs on the island: (1) Police (2) Mariners (3) Teachers (4) Renegades. There is a men's and women's competitioncurrent league champions are Police (Men) (winning the title for the first time since the 1990s) and Renegades (women's). Games are currently played at Warwick Academy. Bermuda u/19 team won the 2010 Caribbean Championships.

Now answer this question: Who won the 2011 Caribbean championships?

Output: The Bermuda Rugby Union team

Article: Birds occupy a wide range of ecological positions. While some birds are generalists, others are highly specialised in their habitat or food requirements. Even within a single habitat, such as a forest, the niches occupied by different species of birds vary, with some species feeding in the forest canopy, others beneath the canopy, and still others on the forest floor. Forest birds may be insectivores, frugivores, and nectarivores. Aquatic birds generally feed by fishing, plant eating, and piracy or kleptoparasitism. Birds of prey specialise in hunting mammals or other birds, while vultures are specialised scavengers. Avivores are animals that are specialized at preying on birds.

Question: What type of birds may be either insectivores, frugivores and nectarivores?
Ans: Forest birds

Input: Mammal
The word "mammal" is modern, from the scientific name Mammalia coined by Carl Linnaeus in 1758, derived from the Latin mamma ("teat, pap"). All female mammals nurse their young with milk, which is secreted from special glands, the mammary glands. According to Mammal Species of the World, 5,416 species were known in 2006. These were grouped in 1,229 genera, 153 families and 29 orders. In 2008 the IUCN completed a five-year, 1,700-scientist Global Mammal Assessment for its IUCN Red List, which counted 5,488 accepted species.

How many families did mammals consist of as of 2006?
Output:
153 families
