[Q]: Passage: Like aluminium, copper is 100% recyclable without any loss of quality, regardless of whether it is in a raw state or contained in a manufactured product. In volume, copper is the third most recycled metal after iron and aluminium. It is estimated that 80% of the copper ever mined is still in use today. According to the International Resource Panel's Metal Stocks in Society report, the global per capita stock of copper in use in society is 3555 kg. Much of this is in more-developed countries (140300 kg per capita) rather than less-developed countries (3040 kg per capita).
[A]: What percent of copper is indestructible?

[Q]: 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.
[A]: What priory were the Dartford sisters not heirs to?

[Q]: Passage: Windows 8 introduces significant changes to the operating system's user interface, many of which are aimed at improving its experience on tablet computers and other touchscreen devices. The new user interface is based on Microsoft's Metro design language, and uses a Start screen similar to that of Windows Phone 7 as the primary means of launching applications. The Start screen displays a customizable array of tiles linking to various apps and desktop programs, some of which can display constantly updated information and content through "live tiles". As a form of multi-tasking, apps can be snapped to the side of a screen. Alongside the traditional Control Panel, a new simplified and touch-optimized settings app known as "PC Settings" is used for basic configuration and user settings. It does not include many of the advanced options still accessible from the normal Control Panel.
[A]:
What is found on the Stop Screen?
