Problem: Gothic architecture:

The Catholic Church prevailed across Europe at this time, influencing not only faith but also wealth and power. Bishops were appointed by the feudal lords (kings, dukes and other landowners) and they often ruled as virtual princes over large estates. The early Medieval periods had seen a rapid growth in monasticism, with several different orders being prevalent and spreading their influence widely. Foremost were the Benedictines whose great abbey churches vastly outnumbered any others in France and England. A part of their influence was that towns developed around them and they became centers of culture, learning and commerce. The Cluniac and Cistercian Orders were prevalent in France, the great monastery at Cluny having established a formula for a well planned monastic site which was then to influence all subsequent monastic building for many centuries.

What church was widespread across Asia at this time?

Problem: During the period between 1582, when the first countries adopted the Gregorian calendar, and 1923, when the last European country adopted it, it was often necessary to indicate the date of some event in both the Julian calendar and in the Gregorian calendar, for example, "10/21 February 1750/51", where the dual year accounts for some countries already beginning their numbered year on 1 January while others were still using some other date. Even before 1582, the year sometimes had to be double dated because of the different beginnings of the year in various countries. Woolley, writing in his biography of John Dee (15271608/9), notes that immediately after 1582 English letter writers "customarily" used "two dates" on their letters, one OS and one NS.
How which calendar did some countries notate the date?

Answer: in both

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Another objection is that it is not always possible to demonstrate falsehood definitively, especially if one is using statistical criteria to evaluate a null hypothesis. More generally it is not always clear, if evidence contradicts a hypothesis, that this is a sign of flaws in the hypothesis rather than of flaws in the evidence. However, this is a misunderstanding of what Popper's philosophy of science sets out to do. Rather than offering a set of instructions that merely need to be followed diligently to achieve science, Popper makes it clear in The Logic of Scientific Discovery that his belief is that the resolution of conflicts between hypotheses and observations can only be a matter of the collective judgment of scientists, in each individual case.
According to Popper, what resolves conflicting hypotheses and observations in the long run?
A: the collective judgment of scientists

Context and question: Expansive interior light has been a feature of Gothic cathedrals since the first structure was opened. The metaphysics of light in the Middle Ages led to clerical belief in its divinity and the importance of its display in holy settings. Much of this belief was based on the writings of Pseudo-Dionysius, a sixth-century mystic whose book, The Celestial Hierarchy, was popular among monks in France. Pseudo-Dionysius held that all light, even light reflected from metals or streamed through windows, was divine. To promote such faith, the abbot in charge of the Saint-Denis church on the north edge of Paris, the Abbot Suger, encouraged architects remodeling the building to make the interior as bright as possible.
What book became unpopular with monks in France and had an effect on how light was used in cathedrals?
Answer: unanswerable

Question: Von Neumann's results have been viewed as a special case of linear programming, where von Neumann's model uses only nonnegative matrices. The study of von Neumann's model of an expanding economy continues to interest mathematical economists with interests in computational economics. This paper has been called the greatest paper in mathematical economics by several authors, who recognized its introduction of fixed-point theorems, linear inequalities, complementary slackness, and saddlepoint duality. In the proceedings of a conference on von Neumann's growth model, Paul Samuelson said that many mathematicians had developed methods useful to economists, but that von Neumann was unique in having made significant contributions to economic theory itself.
Is there an answer to this question: What ideas were utilized in von Neumann's ecocomic model?

Answer: fixed-point theorems, linear inequalities, complementary slackness, and saddlepoint duality

Louis XIV distrusted the Parisians and moved his court to Versailles in 1682, but his reign also saw an unprecedented flourishing of the arts and sciences in Paris. The Comedie-Francaise, the Academy of Painting, and the French Academy of Sciences were founded and made their headquarters in the city. To show that the city was safe against attack, he had the city walls demolished, replacing them with Grands Boulevards. To leave monuments to his reign, he built the College des Quatre-Nations, Place Vendome, Place des Victoires, and began Les Invalides.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What was the reason behind demolishing the city walls?
Ah, so..
To show that the city was safe against attack
