Input: Read this: Glass was used extensively during the Middle Ages. Anglo-Saxon glass has been found across England during archaeological excavations of both settlement and cemetery sites. Glass in the Anglo-Saxon period was used in the manufacture of a range of objects including vessels, beads, windows and was also used in jewelry. From the 10th-century onwards, glass was employed in stained glass windows of churches and cathedrals, with famous examples at Chartres Cathedral and the Basilica of Saint Denis. By the 14th-century, architects were designing buildings with walls of stained glass such as Sainte-Chapelle, Paris, (12031248) and the East end of Gloucester Cathedral. Stained glass had a major revival with Gothic Revival architecture in the 19th-century. With the Renaissance, and a change in architectural style, the use of large stained glass windows became less prevalent. The use of domestic stained glass increased until most substantial houses had glass windows. These were initially small panes leaded together, but with the changes in technology, glass could be manufactured relatively cheaply in increasingly larger sheets. This led to larger window panes, and, in the 20th-century, to much larger windows in ordinary domestic and commercial buildings.
Question: What 13th-century building is an example of stained glass walls?

Output: Sainte-Chapelle

Input: Read this: Once inside the Rotunda for the Charters of Freedom, there are no lines to see the individual documents and visitors are allowed to walk from document to document as they wish. For over 30 years the National Archives have forbidden flash photography but the advent of cameras with automatic flashes have made the rules increasingly difficult to enforce. As a result, all filming, photographing, and videotaping by the public in the exhibition areas has been prohibited since February 25, 2010.
Question: Was it difficult to enforce the ban on the public entering the Rotunda before February 25, 2010?

Output: unanswerable

Input: Read this: In April 1954 Adenauer made his first visit to the USA meeting Nixon, Eisenhower and Dulles. Ratification of EDC was delaying but the US representatives made it clear to Adenauer that EDC would have to become a part of NATO.
Question: Who made it clear to Adenauer that NATO would have to become part of the EDC?

Output: unanswerable

Input: Read this: In Whitehead's view, then, concepts such as "quality", "matter", and "form" are problematic. These "classical" concepts fail to adequately account for change, and overlook the active and experiential nature of the most basic elements of the world. They are useful abstractions, but are not the world's basic building blocks. What is ordinarily conceived of as a single person, for instance, is philosophically described as a continuum of overlapping events. After all, people change all the time, if only because they have aged by another second and had some further experience. These occasions of experience are logically distinct, but are progressively connected in what Whitehead calls a "society" of events. By assuming that enduring objects are the most real and fundamental things in the universe, materialists have mistaken the abstract for the concrete (what Whitehead calls the "fallacy of misplaced concreteness").
Question: Why did he believe those concepts were accurate?

Output:
unanswerable
