In this task, you are given a question and a context passage. You have to answer the question based on the given passage.

[EX Q]: Where are government offices, Context: London is the seat of the Government of the United Kingdom. Many government departments are based close to the Palace of Westminster, particularly along Whitehall, including the Prime Minister's residence at 10 Downing Street. The British Parliament is often referred to as the "Mother of Parliaments" (although this sobriquet was first applied to England itself by John Bright) because it has been the model for most other parliamentary systems. There are 73 Members of Parliament (MPs) from London, who correspond to local parliamentary constituencies in the national Parliament. As of May 2015, 45 are from the Labour Party, 27 are Conservatives, and one is a Liberal Democrat.
[EX A]: Whitehall

[EX Q]: Who found that physical action cannot take on an arbitrary value?, Context: Classical statistical mechanics requires the existence of h (but does not define its value). Eventually, following upon Planck's discovery, it was recognized that physical action cannot take on an arbitrary value. Instead, it must be some multiple of a very small quantity, the "quantum of action", now called the Planck constant. Classical physics cannot explain this fact. In many cases, such as for monochromatic light or for atoms, this quantum of action also implies that only certain energy levels are allowed, and values in between are forbidden.
[EX A]: Planck

[EX Q]: egyptians are also what, Context: According to mtDNA studies by Holden (2005) and Richards et al. (2006), a significant proportion of the maternal lineages of Somalis consists of the M1 haplogroup. This mitochondrial clade is common among Ethiopians and North Africans, particularly Egyptians and Algerians. M1 is believed to have originated in Asia, where its parent M clade represents the majority of mtDNA lineages. This haplogroup is also thought to possibly correlate with the Afro-Asiatic language family:
