question:
Passage: Terra preta (black earth), which is distributed over large areas in the Amazon forest, is now widely accepted as a product of indigenous soil management. The development of this fertile soil allowed agriculture and silviculture in the previously hostile environment; meaning that large portions of the Amazon rainforest are probably the result of centuries of human management, rather than naturally occurring as has previously been supposed. In the region of the Xingu tribe, remains of some of these large settlements in the middle of the Amazon forest were found in 2003 by Michael Heckenberger and colleagues of the University of Florida. Among those were evidence of roads, bridges and large plazas.
answer:
Terra preta is distributor over a small area of what?

Passage: As heirs of the Dominican priory of Poissy in France, the Dartford sisters were also heirs to a tradition of profound learning and piety. Sections of translations of spiritual writings in Dartford's library, such as Suso's Little Book of Eternal Wisdom and Laurent du Bois' Somme le Roi, show that the "ghoostli" link to Europe was not lost in the crossing of the Channel. It survived in the minds of the nuns. Also, the nuns shared a unique identity with Poissy as a religious house founded by a royal house. The English nuns were proud of this heritage, and aware that many of them shared in England's great history as members of the noble class, as seen in the next chapter.
answer:
What priory were the Dartford sisters not heirs to?

question:
Passage: Widely referred to as Highbury, Arsenal Stadium was the club's home from September 1913 until May 2006. The original stadium was designed by the renowned football architect Archibald Leitch, and had a design common to many football grounds in the UK at the time, with a single covered stand and three open-air banks of terracing. The entire stadium was given a massive overhaul in the 1930s: new Art Deco West and East stands were constructed, opening in 1932 and 1936 respectively, and a roof was added to the North Bank terrace, which was bombed during the Second World War and not restored until 1954.
answer:
In which stadium has Arsenal played since 2006?
