Q: Passage: The Crag Group is a geological group outcropping in East Anglia, UK and adjacent areas of the North Sea. Its age ranges from approximately 4.4 to 0.478 million years BP, spanning the late Pliocene and early to middle Pleistocene epochs. It comprises a range of marine and estuarine sands, gravels, silts and clays deposited in a relatively shallow-water, tidally-dominated marine embayment on the western margins of the North Sea basin. The sands are characteristically dark green from glauconite but weather bright orange, with haematite 'iron pans' forming. The lithology of the lower part of the Group is almost entirely flint. The highest formation in the Group, the Wroxham Crag, contains over 10% of far-travelled lithologies, notably quartzite and vein quartz from the Midlands, igneous rocks from Wales, and chert from the Upper Greensand of southeastern England. This exotic rock component was introduced by rivers such as the Bytham River and Proto-Thames. 
 Link Information: The North Sea is a marginal sea of the Atlantic Ocean located between Great Britain (particularly England and Scotland), Denmark, Norway, Germany, the Netherlands, Belgium and France. An epeiric (or "shelf") sea on the European continental shelf, it connects to the ocean through the English Channel in the south and the Norwegian Sea in the north. It is more than 970 km long and 580 km wide, with an area of 570000 km2 Question: What is the area in meters of the sea that is adjacent to the Crag Group?

A: Answer: 570000

Q: Passage: The 19th annual Arab League summit reaffirmed the Arab Peace Initiative first adopted in 2002 (also known as the Beirut Declaration). Arab leaders at the summit urged Israel to accept this initiative. Saudi Foreign Minister Prince Saud al-Faisal said that the plan would have a strong chance of winning international support and of reviving Israeli–Arab peace talks if adopted unanimously by all Arab leaders. The plan, moreover, set up a mechanism to promote the peace plan that would pave the way for Arab countries with no ties to Israel, including Saudi Arabia, to open channels of communications with the Jewish state—a longtime goal for various presidential administrations in the United States. The peace initiative, as Middle Eastern scholars explain, was considered a "great leap from historical resolutions of 1964 and 1967, which had vowed to destroy Israel." Under the plan, Arab nations would recognize Israel if Israel withdrew from land it occupied in the 1967 Arab-Israeli war. Moreover, the plan allows for the creation of a Palestinian state—with its capital in East Jerusalem—and the return of Palestinian refugees based on United Nations General Assembly Resolution 194. The final draft of the plan, moreover, avoided mentioning the phrase "right of return", which has been a point of contention in all previous peace talks; instead it called for a "just solution to the Palestinian refugee problem."

Q: Passage: Liverpool Football Club is an English association football club based in Liverpool, Merseyside, which competes in the top tier of English football, for the 2019–20 season. The club was formed in 1892 following a disagreement between the board of Everton and club president John Houlding, who owned the club's ground, Anfield. The dispute over rent resulted in Everton leaving Anfield for Goodison Park, which left Houlding with an empty stadium. Not content for his ground to lay idle, he created his own club: Liverpool. Liverpool joined the Lancashire League on their foundation before the 1892–93 season. They ended their inaugural season as league champions, and were elected to The Football League soon afterwards. The club remained in The Football League until 1992, when its First Division was superseded as English football's top level by the newly formed Premier League.
 Link Information: Everton played at the Anfield ground from 1884 until 1892. Question: Which ground did the Liverpool Football Club play at longer, Anfield or Goodison Park?

A:
Answer: Anfield
