Problem: Daylight saving time:

Beginning and ending dates are roughly the reverse in the southern hemisphere. For example, mainland Chile observed DST from the second Saturday in October to the second Saturday in March, with transitions at 24:00 local time. The time difference between the United Kingdom and mainland Chile could therefore be five hours during the Northern summer, three hours during the Southern summer and four hours a few weeks per year because of mismatch of changing dates.

In the southern hemisphere, what aspect of DST is about the reverse of that of the northern hemisphere?

A: Beginning and ending dates


Problem: During the Nimrod Expedition led by Ernest Shackleton in 1907, parties led by Edgeworth David became the first to climb Mount Erebus and to reach the South Magnetic Pole. Douglas Mawson, who assumed the leadership of the Magnetic Pole party on their perilous return, went on to lead several expeditions until retiring in 1931. In addition, Shackleton himself and three other members of his expedition made several firsts in December 1908 – February 1909: they were the first humans to traverse the Ross Ice Shelf, the first to traverse the Transantarctic Mountains (via the Beardmore Glacier), and the first to set foot on the South Polar Plateau. An expedition led by Norwegian polar explorer Roald Amundsen from the ship Fram became the first to reach the geographic South Pole on 14 December 1911, using a route from the Bay of Whales and up the Axel Heiberg Glacier. One month later, the doomed Scott Expedition reached the pole.
When did Mawson retire after leading several expeditions?

Answer: 1931


Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
In January 2008 the Wapping presses printed The Sun for the last time and London printing was transferred to Waltham Cross in the Borough of Broxbourne in Hertfordshire, where News International had built what is claimed to be the largest printing centre in Europe with 12 presses. The site also produces The Times and Sunday Times, Daily Telegraph and Sunday Telegraph, Wall Street Journal Europe (also now a Murdoch newspaper), London's Evening Standard and local papers. Northern printing had earlier been switched to a new plant at Knowsley on Merseyside and the Scottish Sun to another new plant at Motherwell near Glasgow. The three print centres represent a £600 million investment by NI and allowed all the titles to be produced with every page in full colour from 2008. The Waltham Cross plant is capable of producing one million copies an hour of a 120-page tabloid newspaper.
How many presses were there at the new printing facility?
A: 12

Question: The site selected for the university was a hill known as Mount Oread, which was owned by former Kansas Governor Charles L. Robinson. Robinson and his wife Sara bestowed the 40-acre (16 ha) site to the State of Kansas in exchange for land elsewhere. The philanthropist Amos Adams Lawrence donated $10,000 of the necessary endowment fund, and the citizens of Lawrence raised the remaining cash by issuing notes backed by Governor Carney. On November 2, 1863, Governor Carney announced that Lawrence had met the conditions to get the state university, and the following year the university was officially organized. The school's Board of Regents held its first meeting in March 1865, which is the event that KU dates its founding from. Work on the first college building began later that year. The university opened for classes on September 12, 1866, and the first class graduated in 1873.
Is there an answer to this question: What was the year in which KU's first roster of students graduated?

Answer: 1873


Transport is one of the four main areas of policy administered by the Mayor of London, however the mayor's financial control does not extend to the longer distance rail network that enters London. In 2007 he assumed responsibility for some local lines, which now form the London Overground network, adding to the existing responsibility for the London Underground, trams and buses. The public transport network is administered by Transport for London (TfL) and is one of the most extensive in the world.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Along with the London Underground, buses and trans, what form of public rail transport was added in 2007 to the Mayor's responsibilities?
Ah, so..
the London Overground network
